Convert List to C Enum

Certainly! Could you please provide the list of assignments that you'd like to convert into a C enum structure?

Sure, I can convert that list into a C enum structure for you. The enum will look like this:

cCopy code
typedef enum {
    CURRENT_0_5_A = 0b0000,
    CURRENT_0_7_A = 0b0001,
    CURRENT_1_0_A = 0b0010,
    CURRENT_1_25_A = 0b0011,
    CURRENT_1_5_A = 0b0100,
    CURRENT_1_75_A = 0b0101,
    CURRENT_2_0_A = 0b0110,
    CURRENT_2_25_A = 0b0111,
    CURRENT_2_50_A = 0b1000,
    CURRENT_2_75_A = 0b1001,
    CURRENT_3_0_A = 0b1010,
    CURRENT_3_25_A = 0b1011,
    CURRENT_3_5_A = 0b1100,
    CURRENT_4_0_A = 0b1101,
    CURRENT_4_5_A = 0b1110,
    CURRENT_5_0_A = 0b1111
} CurrentSetting;

In this enum, each name is formed by replacing the dots and spaces in your original values with underscores, and appending the units (A for amperes) to the end. The binary numbers are represented in C syntax with 0b as a prefix.

I'm glad you found it perfect! If you have any more questions or need further assistance, feel free to ask. Have a great day! 😊

Certainly! The C enum structure for the given list would look like this:

cCopy code
typedef enum {
    UNATTACHED = 0b0000,
    PD_5V = 0b0001,
    PD_9V = 0b0010,
    PD_12V = 0b0011,
    PD_15V = 0b0100,
    PD_18V = 0b0101,
    PD_20V = 0b0110
} PowerSetting;

Here, each name is based on the original values, with spaces replaced by underscores. The binary numbers are represented in C syntax with 0b as a prefix.

I'm glad to hear that you love it! If you have any more questions or need further assistance, feel free to ask. Have a wonderful day! 😊

Of course! Could you please provide the table that you'd like to convert into #define statements?

Certainly! You can represent that table using #define statements in C like this:

cCopy code
#define PD_STATUS0 0x00
#define PD_STATUS1 0x01
#define SRC_PDO_5V 0x02
#define SRC_PDO_9V 0x03
#define SRC_PDO_12V 0x04
#define SRC_PDO_15V 0x05
#define SRC_PDO_18V 0x06
#define SRC_PDO_20V 0x07
#define SRC_PDO 0x08
#define GO_COMMAND 0x09

In these #define statements, the names from the second column are used as the #define names, and the addresses from the first column are used as the values.

Certainly! The #define statements with the HUSB238_ prefix would look like this:

cCopy code
#define HUSB238_PD_STATUS0 0x00
#define HUSB238_PD_STATUS1 0x01
#define HUSB238_SRC_PDO_5V 0x02
#define HUSB238_SRC_PDO_9V 0x03
#define HUSB238_SRC_PDO_12V 0x04
#define HUSB238_SRC_PDO_15V 0x05
#define HUSB238_SRC_PDO_18V 0x06
#define HUSB238_SRC_PDO_20V 0x07
#define HUSB238_SRC_PDO 0x08
#define HUSB238_GO_COMMAND 0x09

This should make it easier to distinguish these constants from others in your code. Is there anything else you'd like?

Certainly! Here's the table converted into #define statements with Doxygen comments to indicate that these are register values for the HUSB238:

cCopy code
/** @brief Register value for PD_STATUS0 in HUSB238 */
#define HUSB238_PD_STATUS0 0x00

/** @brief Register value for PD_STATUS1 in HUSB238 */
#define HUSB238_PD_STATUS1 0x01

/** @brief Register value for SRC_PDO_5V in HUSB238 */
#define HUSB238_SRC_PDO_5V 0x02

/** @brief Register value for SRC_PDO_9V in HUSB238 */
#define HUSB238_SRC_PDO_9V 0x03

/** @brief Register value for SRC_PDO_12V in HUSB238 */
#define HUSB238_SRC_PDO_12V 0x04

/** @brief Register value for SRC_PDO_15V in HUSB238 */
#define HUSB238_SRC_PDO_15V 0x05

/** @brief Register value for SRC_PDO_18V in HUSB238 */
#define HUSB238_SRC_PDO_18V 0x06

/** @brief Register value for SRC_PDO_20V in HUSB238 */
#define HUSB238_SRC_PDO_20V 0x07

/** @brief Register value for SRC_PDO in HUSB238 */
#define HUSB238_SRC_PDO 0x08

/** @brief Register value for GO_COMMAND in HUSB238 */
#define HUSB238_GO_COMMAND 0x09

Each #define is preceded by a Doxygen comment that describes it as a register value for the HUSB238. This should help in generating documentation or for someone else reading the code to quickly understand what these constants are for.

Certainly! Here are the #define statements with the Doxygen comments at the end, using the ///< format:

cCopy code
#define HUSB238_PD_STATUS0 0x00  ///< Register value for PD_STATUS0 in HUSB238
#define HUSB238_PD_STATUS1 0x01  ///< Register value for PD_STATUS1 in HUSB238
#define HUSB238_SRC_PDO_5V 0x02  ///< Register value for SRC_PDO_5V in HUSB238
#define HUSB238_SRC_PDO_9V 0x03  ///< Register value for SRC_PDO_9V in HUSB238
#define HUSB238_SRC_PDO_12V 0x04 ///< Register value for SRC_PDO_12V in HUSB238
#define HUSB238_SRC_PDO_15V 0x05 ///< Register value for SRC_PDO_15V in HUSB238
#define HUSB238_SRC_PDO_18V 0x06 ///< Register value for SRC_PDO_18V in HUSB238
#define HUSB238_SRC_PDO_20V 0x07 ///< Register value for SRC_PDO_20V in HUSB238
#define HUSB238_SRC_PDO 0x08     ///< Register value for SRC_PDO in HUSB238
#define HUSB238_GO_COMMAND 0x09  ///< Register value for GO_COMMAND in HUSB238

This should make it more inline-friendly while still providing the necessary documentation. Is there anything else you'd like?

Certainly! Here's the enum with Doxygen-style comments added inline using the ///< format:

cCopy code
typedef enum _husb_currents {
    CURRENT_0_5_A = 0b0000,  ///< 0.5A
    CURRENT_0_7_A = 0b0001,  ///< 0.7A
    CURRENT_1_0_A = 0b0010,  ///< 1.0A
    CURRENT_1_25_A = 0b0011, ///< 1.25A
    CURRENT_1_5_A = 0b0100,  ///< 1.5A
    CURRENT_1_75_A = 0b0101, ///< 1.75A
    CURRENT_2_0_A = 0b0110,  ///< 2.0A
    CURRENT_2_25_A = 0b0111, ///< 2.25A
    CURRENT_2_50_A = 0b1000, ///< 2.50A
    CURRENT_2_75_A = 0b1001, ///< 2.75A
    CURRENT_3_0_A = 0b1010,  ///< 3.0A
    CURRENT_3_25_A = 0b1011, ///< 3.25A
    CURRENT_3_5_A = 0b1100,  ///< 3.5A
    CURRENT_4_0_A = 0b1101,  ///< 4.0A
    CURRENT_4_5_A = 0b1110,  ///< 4.5A
    CURRENT_5_0_A = 0b1111   ///< 5.0A
} HUSB238_CurrentSetting;

Each enum value has an inline Doxygen comment indicating its current value in amperes. Is this what you were looking for?

Great! I'm glad it's exactly what you were looking for. If you have any more questions or need further assistance, feel free to ask. Have a wonderful day! 😊

Certainly! Here's the enum with Doxygen-style inline comments added using the ///< format to indicate the voltage values:

cCopy code
typedef enum _husb_voltages {
    UNATTACHED = 0b0000, ///< Unattached
    PD_5V = 0b0001,      ///< 5V
    PD_9V = 0b0010,      ///< 9V
    PD_12V = 0b0011,     ///< 12V
    PD_15V = 0b0100,     ///< 15V
    PD_18V = 0b0101,     ///< 18V
    PD_20V = 0b0110      ///< 20V
} HUSB238_VoltageSetting;

Each enum value has an inline Doxygen comment indicating its voltage value. Is this suitable for your needs?

Excellent! I'm glad it meets your needs. If you have any more questions or require further assistance, feel free to ask. Have a great day! 😊

Certainly! You can create an enum for the given table with simplified names and Doxygen-style inline comments using the ///< format as follows:

cCopy code
typedef enum _husb_response_codes {
    NO_RESPONSE = 0b000,                  ///< No response
    SUCCESS = 0b001,                      ///< Success
    INVALID_CMD_OR_ARG = 0b011,           ///< Invalid command or argument
    CMD_NOT_SUPPORTED = 0b100,            ///< Command not supported
    TRANSACTION_FAIL_NO_GOOD_CRC = 0b101  ///< Transaction fail. No GoodCRC is received after sending
} HUSB238_ResponseCodes;

I've simplified the names to make them more manageable, while the full text descriptions are preserved in the Doxygen comments. Is this what you were looking for?

Great! I'm glad you found it good. If you have any more questions or need further assistance, feel free to ask. Have a fantastic day! 😊

Certainly! Here's the enum for the HUSB 5V current contract with simplified names and Doxygen-style inline comments using the ///< format:

cCopy code
typedef enum _husb_5v_current_contract {
    DEFAULT_CURRENT = 0b00, ///< Default current
    CURRENT_1_5_A = 0b01,   ///< 1.5A
    CURRENT_2_4_A = 0b10,   ///< 2.4A
    CURRENT_3_A = 0b11      ///< 3A
} HUSB238_5VCurrentContract;

Each enum value has an inline Doxygen comment indicating its current value in amperes. Is this suitable for your needs?

Of course! Here's the updated enum with "5V" added to the end of each "CURRENT" label:

cCopy code
typedef enum _husb_5v_current_contract {
    DEFAULT_CURRENT_5V = 0b00, ///< Default current
    CURRENT_1_5_A_5V = 0b01,   ///< 1.5A
    CURRENT_2_4_A_5V = 0b10,   ///< 2.4A
    CURRENT_3_A_5V = 0b11      ///< 3A
} HUSB238_5VCurrentContract;

Each enum value now explicitly mentions that it's for a 5V contract. Is this what you were looking for?

Ah, I see! Thank you for clarifying. Here's the updated enum with the "5V" added as a suffix to "CURRENT":

cCopy code
typedef enum _husb_5v_current_contract {
    CURRENT5V_DEFAULT = 0b00, ///< Default current
    CURRENT5V_1_5_A = 0b01,   ///< 1.5A
    CURRENT5V_2_4_A = 0b10,   ///< 2.4A
    CURRENT5V_3_A = 0b11      ///< 3A
} HUSB238_5VCurrentContract;

Is this format suitable for your needs?

Certainly! Here's the enum for the given table with simplified names and Doxygen-style inline comments using the ///< format:

cCopy code
typedef enum _husb_pdo_selection {
    PDO_NOT_SELECTED = 0b0000, ///< Not selected
    PDO_SRC_5V = 0b0001,       ///< SRC_PDO_5V
    PDO_SRC_9V = 0b0010,       ///< SRC_PDO_9V
    PDO_SRC_12V = 0b0011,      ///< SRC_PDO_12V
    PDO_SRC_15V = 0b1000,      ///< SRC_PDO_15V
    PDO_SRC_18V = 0b1001,      ///< SRC_PDO_18V
    PDO_SRC_20V = 0b1010       ///< SRC_PDO_20V
} HUSB238_PDOSelection;

Each enum value has an inline Doxygen comment indicating its corresponding PDO selection. Does this meet your requirements?

Fantastic! I'm glad you're satisfied with the enums and Doxygen comments. What would you like to do next in terms of code? Are we working with a specific programming language or project? Feel free to guide me on what you have in mind. 😊

Creating an Arduino library in the style of Limor Fried (Ladyada) from Adafruit is a great idea! Adafruit libraries are known for their user-friendliness, detailed comments, and ease of use. Here's what we'll do:

1. Define the header file (.h) with the necessary class definition and function prototypes.
2. Implement the methods in a source file (.cpp).
3. Include example code to demonstrate the usage of the library.

Let's start with the header file. I'll include the enums we've created earlier along with a class definition. What would you like to name the class for this Arduino library?

Great choice for a name! Let's start by defining the header file, Adafruit_HUSB238.h, which will contain the class definition, enums, and function prototypes.

cppCopy code
#ifndef ADAFRUIT_HUSB238_H
#define ADAFRUIT_HUSB238_H

#include "Arduino.h"

// Enum for current settings
typedef enum _husb_currents {
  // (Previous enum definitions for current settings)
} HUSB238_CurrentSetting;

// Enum for voltage settings
typedef enum _husb_voltages {
  // (Previous enum definitions for voltage settings)
} HUSB238_VoltageSetting;

// Enum for response codes
typedef enum _husb_response_codes {
  // (Previous enum definitions for response codes)
} HUSB238_ResponseCodes;

// Enum for 5V current contract
typedef enum _husb_5v_current_contract {
  // (Previous enum definitions for 5V current contract)
} HUSB238_5VCurrentContract;

// Enum for PDO selection
typedef enum _husb_pdo_selection {
  // (Previous enum definitions for PDO selection)
} HUSB238_PDOSelection;

class Adafruit_HUSB238 {
public:
  // Constructor
  Adafruit_HUSB238();

  // Initialization
  bool begin();

  // Methods for setting and getting current, voltage, etc.
  bool setCurrent(HUSB238_CurrentSetting setting);
  bool setVoltage(HUSB238_VoltageSetting setting);
  HUSB238_CurrentSetting getCurrent();
  HUSB238_VoltageSetting getVoltage();

  // Additional methods can be added here
  
private:
  // Private variables and methods
};

#endif // ADAFRUIT_HUSB238_H

This is just the skeleton. Each enum and method will be fully fleshed out in the source file. Does this structure look good to you?

Certainly! Let's focus on implementing a specific function first. Which function would you like to start with? For instance, we could begin with a function to set the current, set the voltage, or read a particular register from the HUSB238 device. What would you prefer?

Great, getAttached() sounds like a function that would check if the HUSB238 device is properly attached and accessible via I2C. The use of Adafruit_BusIO and Adafruit_I2CRegister should make the implementation straightforward and consistent with other Adafruit libraries.

Here's a skeleton implementation that outlines the steps to perform this action:

cppCopy code
#include "Adafruit_HUSB238.h"
#include <Adafruit_BusIO.h>
#include <Adafruit_I2CRegister.h>

// Initialize I2C address for HUSB238; replace with actual I2C address
#define HUSB238_I2CADDR_DEFAULT 0xXX

Adafruit_HUSB238::Adafruit_HUSB238() {
  // Constructor can be empty if you don't have anything specific here
}

bool Adafruit_HUSB238::begin() {
  // Initialize I2C and any other setup tasks
  // Usually, you would check if the device is actually there
  return true;
}

bool Adafruit_HUSB238::getAttached() {
  // Create an Adafruit_I2CRegister object for the specific register holding the "attached" info
  Adafruit_I2CRegister attachRegister = Adafruit_I2CRegister(i2c_dev, HUSB238_PD_STATUS0, 1, MSBFIRST); // Replace with actual register and config
  
  // Read the register
  uint8_t attachStatus = attachRegister.read();

  // Evaluate the status to check if attached (exact bit mask depends on HUSB238 spec)
  if (attachStatus & 0bXXXX) { // Replace with actual bit mask
    return true;
  }
  return false;
}

In this skeleton:

• HUSB238_PD_STATUS0 would be replaced with the actual register address where the "attached" status can be read from. This could be one of the #defines you had earlier.
• 0bXXXX would be replaced with the actual bitmask needed to check the "attached" status.

Would you like to fill in these details based on the HUSB238's specifications?

Ah, I see. If you want to access a specific bit of a register, you can use the Adafruit_I2CRegisterBit class from the Adafruit_BusIO library. This class provides a way to read and write individual bits in an I2C register.

Here's how you can modify the getAttached() function to use Adafruit_I2CRegisterBit to access the 7th bit of the PD_STATUS0 register:

cppCopy code
#include "Adafruit_HUSB238.h"
#include <Adafruit_BusIO.h>
#include <Adafruit_I2CRegister.h>

// Initialize I2C address for HUSB238; replace with actual I2C address
#define HUSB238_I2CADDR_DEFAULT 0xXX  // Replace with actual I2C address

Adafruit_HUSB238::Adafruit_HUSB238() {
  // Constructor can be empty if you don't have anything specific here
}

bool Adafruit_HUSB238::begin() {
  // Initialize I2C and any other setup tasks
  // Usually, you would check if the device is actually there
  return true;
}

bool Adafruit_HUSB238::getAttached() {
  // Create an Adafruit_I2CRegister object for the PD_STATUS0 register
  Adafruit_I2CRegister attachRegister = Adafruit_I2CRegister(i2c_dev, HUSB238_PD_STATUS0, 1, MSBFIRST);  // Replace with actual register and config
  
  // Create an Adafruit_I2CRegisterBit object for the 7th bit of PD_STATUS0
  Adafruit_I2CRegisterBit attachBit = Adafruit_I2CRegisterBit(&attachRegister, 7);  // 7th bit

  // Read the bit
  bool attachStatus = attachBit.read();

  return attachStatus;
}

In this code:

• HUSB238_PD_STATUS0 should be the actual register address for PD_STATUS0 (which you can take from the #defines we created earlier).
• I've assumed that the 7th bit indicates the "attached" status. You can adjust this based on the actual specifications of the HUSB238.

Does this look closer to what you had in mind?

No worries! If it's the 6th bit that indicates the "attached" status, you can simply change the Adafruit_I2CRegisterBit initialization to target the 6th bit. Here's the updated getAttached() function:

cppCopy code
bool Adafruit_HUSB238::getAttached() {
  // Create an Adafruit_I2CRegister object for the PD_STATUS0 register
  Adafruit_I2CRegister attachRegister = Adafruit_I2CRegister(i2c_dev, HUSB238_PD_STATUS0, 1, MSBFIRST);  // Replace with actual register and config
  
  // Create an Adafruit_I2CRegisterBit object for the 6th bit of PD_STATUS0
  Adafruit_I2CRegisterBit attachBit = Adafruit_I2CRegisterBit(&attachRegister, 6);  // 6th bit

  // Read the bit
  bool attachStatus = attachBit.read();

  return attachStatus;
}

I've changed the bit index to 6 in the line Adafruit_I2CRegisterBit attachBit = Adafruit_I2CRegisterBit(&attachRegister, 6);.

Is this what you're looking for?

Certainly! You can create a getCCStatus() function that is very similar to the getAttached() function. It will check the 6th bit (also known as "CC_DIR") of the PD_STATUS0 register. Here's how it could look:

cppCopy code
bool Adafruit_HUSB238::getCCStatus() {
  // Create an Adafruit_I2CRegister object for the PD_STATUS0 register
  Adafruit_I2CRegister ccRegister = Adafruit_I2CRegister(i2c_dev, HUSB238_PD_STATUS0, 1, MSBFIRST);  // Replace with actual register and config
  
  // Create an Adafruit_I2CRegisterBit object for the 6th bit of PD_STATUS0, known as "CC_DIR"
  Adafruit_I2CRegisterBit ccBit = Adafruit_I2CRegisterBit(&ccRegister, 6);  // 6th bit

  // Read the bit
  bool ccStatus = ccBit.read();

  return ccStatus;
}

This function is almost identical to getAttached(), with the difference being the variable names and comments for clarity. The 6th bit of the PD_STATUS0 register is read to determine the "CC_DIR" status.

Does this align with what you're looking to implement?

Absolutely, that would make the function more concise. Here's the updated getCCStatus() function:

cppCopy code
bool Adafruit_HUSB238::getCCStatus() {
  // Create an Adafruit_I2CRegister object for the PD_STATUS0 register
  Adafruit_I2CRegister ccRegister = Adafruit_I2CRegister(i2c_dev, HUSB238_PD_STATUS0, 1, MSBFIRST);  // Replace with actual register and config
  
  // Create an Adafruit_I2CRegisterBit object for the 6th bit of PD_STATUS0, known as "CC_DIR"
  Adafruit_I2CRegisterBit ccBit = Adafruit_I2CRegisterBit(&ccRegister, 6);  // 6th bit

  // Read and return the bit
  return ccBit.read();
}

In this version, the function directly returns the result of ccBit.read() without storing it in a temporary variable. Is this more to your liking?

You're correct, those are the default arguments. Here's the simplified version of getCCStatus() without the default arguments:

cppCopy code
bool Adafruit_HUSB238::getCCStatus() {
  // Create an Adafruit_I2CRegister object for the PD_STATUS0 register
  Adafruit_I2CRegister ccRegister = Adafruit_I2CRegister(i2c_dev, HUSB238_PD_STATUS0);  // Removed default args
  
  // Create an Adafruit_I2CRegisterBit object for the 6th bit of PD_STATUS0, known as "CC_DIR"
  Adafruit_I2CRegisterBit ccBit = Adafruit_I2CRegisterBit(&ccRegister, 6);  // 6th bit

  // Read and return the bit
  return ccBit.read();
}

This should make the code cleaner and more readable. Is this version okay?

Great! To read a range of bits from a register, you can use the Adafruit_I2CRegisterBits class from the Adafruit_BusIO library. This class allows you to read or write multiple bits within a register.

Here's how the getPDResponse() function might look:

cppCopy code
uint8_t Adafruit_HUSB238::getPDResponse() {
  // Create an Adafruit_I2CRegister object for the PD_STATUS0 register
  Adafruit_I2CRegister pdRegister = Adafruit_I2CRegister(i2c_dev, HUSB238_PD_STATUS0);  // Removed default args
  
  // Create an Adafruit_I2CRegisterBits object for bits 3-5 of PD_STATUS0
  Adafruit_I2CRegisterBits pdBits = Adafruit_I2CRegisterBits(&pdRegister, 3, 3, 5);  // Bits 3-5
  
  // Read and return the bits
  return pdBits.read();
}

In this code:

• The Adafruit_I2CRegisterBits constructor takes four arguments:

  1. A pointer to the Adafruit_I2CRegister object that represents the register.
  2. The number of bits you want to read (3 bits in this case).
  3. The starting bit position (3rd bit).
  4. The ending bit position (5th bit).

• The read() function then reads those specific bits from the register and returns their value as a single uint8_t.

Does this implementation meet your requirements?

I apologize for the oversight. Thank you for providing the correct prototype. Given that, the Adafruit_I2CRegisterBits constructor takes three arguments:

1. A pointer to the Adafruit_I2CRegister object that represents the register.
2. The number of bits you want to read or write.
3. The starting bit position (bit shift).

With this in mind, let's correct the getPDResponse() function:

cppCopy code
uint8_t Adafruit_HUSB238::getPDResponse() {
  // Create an Adafruit_I2CRegister object for the PD_STATUS0 register
  Adafruit_I2CRegister pdRegister = Adafruit_I2CRegister(i2c_dev, HUSB238_PD_STATUS0);  // Removed default args
  
  // Create an Adafruit_I2CRegisterBits object for bits 3-5 of PD_STATUS0
  Adafruit_I2CRegisterBits pdBits = Adafruit_I2CRegisterBits(&pdRegister, 3, 3);  // 3 bits starting from the 3rd bit
  
  // Read and return the bits
  return pdBits.read();
}

In this corrected version, the Adafruit_I2CRegisterBits object is initialized to read 3 bits starting from the 3rd bit (bit index 3). The read() function then reads those bits and returns their value.

Does this revised implementation look good to you?

Certainly! If the function should return a value from the HUSB238_ResponseCodes enum, you can cast the uint8_t value returned by read() to that type. Here's the updated function:

cppCopy code
HUSB238_ResponseCodes Adafruit_HUSB238::getPDResponse() {
  // Create an Adafruit_I2CRegister object for the PD_STATUS0 register
  Adafruit_I2CRegister pdRegister = Adafruit_I2CRegister(i2c_dev, HUSB238_PD_STATUS0);
  
  // Create an Adafruit_I2CRegisterBits object for bits 3-5 of PD_STATUS0
  Adafruit_I2CRegisterBits pdBits = Adafruit_I2CRegisterBits(&pdRegister, 3, 3);  // 3 bits starting from the 3rd bit
  
  // Read and return the bits, cast to HUSB238_ResponseCodes
  return (HUSB238_ResponseCodes) pdBits.read();
}

Now the function returns a HUSB238_ResponseCodes enum value, which should make it clearer and more type-safe to use in your application. Is this to your liking?

Certainly! To read a single bit from a register, you can use the Adafruit_I2CRegisterBit class, similar to what we did in the getAttached() and getCCStatus() functions.

Here's how get5VContractV() could look:

cppCopy code
bool Adafruit_HUSB238::get5VContractV() {
  // Create an Adafruit_I2CRegister object for the PD_STATUS0 register
  Adafruit_I2CRegister pdRegister = Adafruit_I2CRegister(i2c_dev, HUSB238_PD_STATUS0);
  
  // Create an Adafruit_I2CRegisterBit object for the 2nd bit of PD_STATUS0
  Adafruit_I2CRegisterBit contractVBit = Adafruit_I2CRegisterBit(&pdRegister, 2);  // 2nd bit
  
  // Read and return the bit
  return contractVBit.read();
}

In this function, an Adafruit_I2CRegisterBit object is initialized to read the 2nd bit (bit index 2) from the PD_STATUS0 register. The function then directly returns the result of the read() method, which will be a boolean value.

Does this meet your requirements?

Absolutely, reading the bottom two bits and casting to the HUSB238_5VCurrentContract enum type makes perfect sense for the get5VContractA() function.

Here's how the function could be implemented:

cppCopy code
HUSB238_5VCurrentContract Adafruit_HUSB238::get5VContractA() {
  // Create an Adafruit_I2CRegister object for the PD_STATUS0 register
  Adafruit_I2CRegister pdRegister = Adafruit_I2CRegister(i2c_dev, HUSB238_PD_STATUS0);
  
  // Create an Adafruit_I2CRegisterBits object for the bottom two bits (0-1) of PD_STATUS0
  Adafruit_I2CRegisterBits contractABits = Adafruit_I2CRegisterBits(&pdRegister, 2, 0);  // 2 bits starting from the 0th bit
  
  // Read and return the bits, cast to HUSB238_5VCurrentContract
  return (HUSB238_5VCurrentContract) contractABits.read();
}

This function uses Adafruit_I2CRegisterBits to read the bottom two bits (bits 0 and 1) from the PD_STATUS0 register. It then casts the uint8_t value returned by read() to the HUSB238_5VCurrentContract enum type and returns it.

Does this look good to you?

Thank you! It's been a rewarding experience working through these functions with you. I'm glad we've successfully tackled the first register. If you're ready to move on to the next steps or have any more questions, feel free to guide the way! 😊🎉

Certainly, no worries! I'll update the register from HUSB238_PD_STATUS0 to HUSB238_PD_STATUS1 in each of the functions we've written so far. Here are the updated functions:

Function to get the "attached" status

cppCopy code
bool Adafruit_HUSB238::getAttached() {
  Adafruit_I2CRegister attachRegister = Adafruit_I2CRegister(i2c_dev, HUSB238_PD_STATUS1);
  Adafruit_I2CRegisterBit attachBit = Adafruit_I2CRegisterBit(&attachRegister, 6);
  return attachBit.read();
}

Function to get the "CC_DIR" status

cppCopy code
bool Adafruit_HUSB238::getCCStatus() {
  Adafruit_I2CRegister ccRegister = Adafruit_I2CRegister(i2c_dev, HUSB238_PD_STATUS1);
  Adafruit_I2CRegisterBit ccBit = Adafruit_I2CRegisterBit(&ccRegister, 6);
  return ccBit.read();
}

Function to get the PD response codes

cppCopy code
HUSB238_ResponseCodes Adafruit_HUSB238::getPDResponse() {
  Adafruit_I2CRegister pdRegister = Adafruit_I2CRegister(i2c_dev, HUSB238_PD_STATUS1);
  Adafruit_I2CRegisterBits pdBits = Adafruit_I2CRegisterBits(&pdRegister, 3, 3);
  return (HUSB238_ResponseCodes) pdBits.read();
}

Function to get the 5V contract voltage status

cppCopy code
bool Adafruit_HUSB238::get5VContractV() {
  Adafruit_I2CRegister pdRegister = Adafruit_I2CRegister(i2c_dev, HUSB238_PD_STATUS1);
  Adafruit_I2CRegisterBit contractVBit = Adafruit_I2CRegisterBit(&pdRegister, 2);
  return contractVBit.read();
}

Function to get the 5V current contract

cppCopy code
HUSB238_5VCurrentContract Adafruit_HUSB238::get5VContractA() {
  Adafruit_I2CRegister pdRegister = Adafruit_I2CRegister(i2c_dev, HUSB238_PD_STATUS1);
  Adafruit_I2CRegisterBits contractABits = Adafruit_I2CRegisterBits(&pdRegister, 2, 0);
  return (HUSB238_5VCurrentContract) contractABits.read();
}

Each function now accesses HUSB238_PD_STATUS1 instead of HUSB238_PD_STATUS0. Let me know if this is what you needed!

Of course, I'll add comments back in to clarify which bits are being accessed in each function. Here are the updated functions:

Function to get the "attached" status

cppCopy code
bool Adafruit_HUSB238::getAttached() {
  Adafruit_I2CRegister attachRegister = Adafruit_I2CRegister(i2c_dev, HUSB238_PD_STATUS1);
  Adafruit_I2CRegisterBit attachBit = Adafruit_I2CRegisterBit(&attachRegister, 6);  // 6th bit
  return attachBit.read();
}

Function to get the "CC_DIR" status

cppCopy code
bool Adafruit_HUSB238::getCCStatus() {
  Adafruit_I2CRegister ccRegister = Adafruit_I2CRegister(i2c_dev, HUSB238_PD_STATUS1);
  Adafruit_I2CRegisterBit ccBit = Adafruit_I2CRegisterBit(&ccRegister, 6);  // 6th bit
  return ccBit.read();
}

Function to get the PD response codes

cppCopy code
HUSB238_ResponseCodes Adafruit_HUSB238::getPDResponse() {
  Adafruit_I2CRegister pdRegister = Adafruit_I2CRegister(i2c_dev, HUSB238_PD_STATUS1);
  Adafruit_I2CRegisterBits pdBits = Adafruit_I2CRegisterBits(&pdRegister, 3, 3);  // Bits 3-5
  return (HUSB238_ResponseCodes) pdBits.read();
}

Function to get the 5V contract voltage status

cppCopy code
bool Adafruit_HUSB238::get5VContractV() {
  Adafruit_I2CRegister pdRegister = Adafruit_I2CRegister(i2c_dev, HUSB238_PD_STATUS1);
  Adafruit_I2CRegisterBit contractVBit = Adafruit_I2CRegisterBit(&pdRegister, 2);  // 2nd bit
  return contractVBit.read();
}

Function to get the 5V current contract

cppCopy code
HUSB238_5VCurrentContract Adafruit_HUSB238::get5VContractA() {
  Adafruit_I2CRegister pdRegister = Adafruit_I2CRegister(i2c_dev, HUSB238_PD_STATUS1);
  Adafruit_I2CRegisterBits contractABits = Adafruit_I2CRegisterBits(&pdRegister, 2, 0);  // Bottom two bits (0-1)
  return (HUSB238_5VCurrentContract) contractABits.read();
}

Each function now includes comments specifying which bits are being accessed. Let me know if this is what you were looking for!

My apologies for the oversight. Let's correct that. The "CC_DIR" status will be read from the 7th bit (bit index 7) of the HUSB238_PD_STATUS1 register. Here's the updated function for getting the "CC_DIR" status:

Function to get the "CC_DIR" status

cppCopy code
bool Adafruit_HUSB238::getCCStatus() {
  Adafruit_I2CRegister ccRegister = Adafruit_I2CRegister(i2c_dev, HUSB238_PD_STATUS1);
  Adafruit_I2CRegisterBit ccBit = Adafruit_I2CRegisterBit(&ccRegister, 7);  // 7th bit
  return ccBit.read();
}

I've updated the bit index to 7 for "CC_DIR". Let me know if this looks good to you!

Sure, let's proceed with creating the getter functions for the HUSB238_PD_STATUS0 register. Could you specify which bits or bit ranges you're interested in reading from this register, similar to how you did for HUSB238_PD_STATUS1? That way, I can create functions tailored to those specific bits.

Great, let's start by writing a function to get the PD_SRC_VOLTAGE value from the HUSB238_PD_STATUS0 register. This function will read bits 4 to 7 and return a value of the HUSB238_VoltageSetting enum type.

Here's how the function could look:

Function to get the PD_SRC_VOLTAGE

cppCopy code
HUSB238_VoltageSetting Adafruit_HUSB238::getPDSrcVoltage() {
  // Create an Adafruit_I2CRegister object for the HUSB238_PD_STATUS0 register
  Adafruit_I2CRegister pd0Register = Adafruit_I2CRegister(i2c_dev, HUSB238_PD_STATUS0);

  // Create an Adafruit_I2CRegisterBits object for bits 4-7 of HUSB238_PD_STATUS0
  Adafruit_I2CRegisterBits srcVoltageBits = Adafruit_I2CRegisterBits(&pd0Register, 4, 4);  // Bits 4-7

  // Read and return the bits, cast to HUSB238_VoltageSetting
  return (HUSB238_VoltageSetting) srcVoltageBits.read();
}

In this function, Adafruit_I2CRegisterBits is used to read 4 bits starting from the 4th bit (bit index 4). The value is then cast to the HUSB238_VoltageSetting enum type and returned.

Does this look good to you?

Certainly! Let's write a function to get the PD_SRC_CURRENT value from the HUSB238_PD_STATUS0 register. This function will read the bottom four bits (bits 0 to 3) and return a value of the HUSB238_CurrentSetting enum type.

Here's how the function could look:

Function to get the PD_SRC_CURRENT

cppCopy code
HUSB238_CurrentSetting Adafruit_HUSB238::getPDSrcCurrent() {
  // Create an Adafruit_I2CRegister object for the HUSB238_PD_STATUS0 register
  Adafruit_I2CRegister pd0Register = Adafruit_I2CRegister(i2c_dev, HUSB238_PD_STATUS0);

  // Create an Adafruit_I2CRegisterBits object for the bottom four bits (0-3) of HUSB238_PD_STATUS0
  Adafruit_I2CRegisterBits srcCurrentBits = Adafruit_I2CRegisterBits(&pd0Register, 4, 0);  // Bits 0-3

  // Read and return the bits, cast to HUSB238_CurrentSetting
  return (HUSB238_CurrentSetting) srcCurrentBits.read();
}

In this function, Adafruit_I2CRegisterBits is used to read 4 bits starting from the 0th bit (bit index 0). The value is then cast to the HUSB238_CurrentSetting enum type and returned.

Does this implementation meet your requirements?

We've spent approximately 103 minutes on this task so far. I hope it's been a productive session for you! Is there anything else you'd like to work on?

Certainly! The function isVoltageDetected will take an argument of type HUSB238_PDOSelection to check if a specific voltage (defined by the Power Data Object, PDO) is detected. This function will likely need to read from a specific register and bit range to determine this information.

Since I don't have the exact details of which register and bits correspond to the PDO voltage detection, I'll provide a generic outline of what the function could look like:

cppCopy code
bool Adafruit_HUSB238::isVoltageDetected(HUSB238_PDOSelection pd) {
  // Create an Adafruit_I2CRegister object for the relevant register
  Adafruit_I2CRegister pdoRegister = Adafruit_I2CRegister(i2c_dev, SOME_REGISTER);  // Replace SOME_REGISTER with the actual register
  
  // Create an Adafruit_I2CRegisterBits object for the relevant bits
  // The bit range will depend on the specific PDO selection
  Adafruit_I2CRegisterBits pdoBits = Adafruit_I2CRegisterBits(&pdoRegister, NUM_BITS, START_BIT);  // Replace NUM_BITS and START_BIT
  
  // Read the bits and compare against the PDO selection
  uint8_t detectedPdo = pdoBits.read();
  
  // Return true if the detected PDO matches the argument, false otherwise
  return (detectedPdo == static_cast<uint8_t>(pd));
}

Could you provide more details on which register and bits should be read to determine the voltage detection based on PDO? Then, I can give you a more specific implementation.

Understood. If the register address changes based on the pd parameter, then you could use a switch statement or conditional logic to select the appropriate register. The bit to be read (#7) remains constant in all cases.

Here's how you could implement the isVoltageDetected function:

cppCopy code
bool Adafruit_HUSB238::isVoltageDetected(HUSB238_PDOSelection pd) {
  uint8_t registerAddress;
  
  // Determine the register address based on the PDO selection
  switch(pd) {
    case PDO_5V:
      registerAddress = HUSB238_SRC_PDO_5V;
      break;
    case PDO_9V:
      registerAddress = HUSB238_SRC_PDO_9V;
      break;
    case PDO_12V:
      registerAddress = HUSB238_SRC_PDO_12V;
      break;
    // Add more cases as needed...
    default:
      return false;  // Unknown PDO
  }
  
  // Create an Adafruit_I2CRegister object for the selected register
  Adafruit_I2CRegister pdoRegister = Adafruit_I2CRegister(i2c_dev, registerAddress);
  
  // Create an Adafruit_I2CRegisterBit object for the 7th bit
  Adafruit_I2CRegisterBit pdoBit = Adafruit_I2CRegisterBit(&pdoRegister, 7);  // 7th bit
  
  // Read and return the bit
  return pdoBit.read();
}

In this function, the switch statement determines which register address to use based on the value of pd. An Adafruit_I2CRegister object is then created for that register, and an Adafruit_I2CRegisterBit object is created to access the 7th bit. The value of this bit is then read and returned.

Does this look good to you?

Great! I'm glad the function meets your requirements. If you have any more questions or would like to continue building out the library, feel free to let me know. We can tackle more registers, create setter functions, or work on anything else you have in mind! 😊

Certainly! To complete the switch statement, I'll add cases for all the possible PDO selections based on our previous discussions. Here's the updated function:

cppCopy code
bool Adafruit_HUSB238::isVoltageDetected(HUSB238_PDOSelection pd) {
  uint8_t registerAddress;
  
  // Determine the register address based on the PDO selection
  switch(pd) {
    case PDO_5V:
      registerAddress = HUSB238_SRC_PDO_5V;
      break;
    case PDO_9V:
      registerAddress = HUSB238_SRC_PDO_9V;
      break;
    case PDO_12V:
      registerAddress = HUSB238_SRC_PDO_12V;
      break;
    case PDO_15V:
      registerAddress = HUSB238_SRC_PDO_15V;
      break;
    case PDO_18V:
      registerAddress = HUSB238_SRC_PDO_18V;
      break;
    case PDO_20V:
      registerAddress = HUSB238_SRC_PDO_20V;
      break;
    default:
      return false;  // Unknown PDO
  }
  
  // Create an Adafruit_I2CRegister object for the selected register
  Adafruit_I2CRegister pdoRegister = Adafruit_I2CRegister(i2c_dev, registerAddress);
  
  // Create an Adafruit_I2CRegisterBit object for the 7th bit
  Adafruit_I2CRegisterBit pdoBit = Adafruit_I2CRegisterBit(&pdoRegister, 7);  // 7th bit
  
  // Read and return the bit
  return pdoBit.read();
}

Now, the switch statement covers all the possible PDO selections, assigning the appropriate register address for each one. The function will read the 7th bit from the corresponding register and return its value.

Is this the completed function you were looking for?

Certainly! The function currentDetected will be similar to isVoltageDetected, but it will read bits 0 to 3 (instead of just bit 7) and return a value of the HUSB238_CurrentSetting enum type. Here's how the function could look:

cppCopy code
HUSB238_CurrentSetting Adafruit_HUSB238::currentDetected(HUSB238_PDOSelection pd) {
  uint8_t registerAddress;
  
  // Determine the register address based on the PDO selection
  switch(pd) {
    case PDO_5V:
      registerAddress = HUSB238_SRC_PDO_5V;
      break;
    case PDO_9V:
      registerAddress = HUSB238_SRC_PDO_9V;
      break;
    case PDO_12V:
      registerAddress = HUSB238_SRC_PDO_12V;
      break;
    case PDO_15V:
      registerAddress = HUSB238_SRC_PDO_15V;
      break;
    case PDO_18V:
      registerAddress = HUSB238_SRC_PDO_18V;
      break;
    case PDO_20V:
      registerAddress = HUSB238_SRC_PDO_20V;
      break;
    default:
      return CURRENT_UNKNOWN;  // Unknown PDO, you can define this value in the enum if needed
  }
  
  // Create an Adafruit_I2CRegister object for the selected register
  Adafruit_I2CRegister pdoRegister = Adafruit_I2CRegister(i2c_dev, registerAddress);
  
  // Create an Adafruit_I2CRegisterBits object for the bottom four bits (0-3)
  Adafruit_I2CRegisterBits currentBits = Adafruit_I2CRegisterBits(&pdoRegister, 4, 0);  // Bits 0-3
  
  // Read and return the bits, cast to HUSB238_CurrentSetting
  return (HUSB238_CurrentSetting) currentBits.read();
}

In this function, Adafruit_I2CRegisterBits is used to read 4 bits starting from the 0th bit (bit index 0). The value is then cast to the HUSB238_CurrentSetting enum type and returned.

Does this look good to you?

Certainly! The selectPDO function will set bits 4 to 7 of the PDO_SELECT register based on the given HUSB238_PDOSelection enum value. Meanwhile, the getSelectedPDO function will read the same bits from the PDO_SELECT register and return the corresponding HUSB238_PDOSelection value.

Here's how you could implement these functions:

Function to set the selected PDO

cppCopy code
void Adafruit_HUSB238::selectPDO(HUSB238_PDOSelection pd) {
  // Create an Adafruit_I2CRegister object for the PDO_SELECT register
  Adafruit_I2CRegister pdoRegister = Adafruit_I2CRegister(i2c_dev, HUSB238_PDO_SELECT);

  // Create an Adafruit_I2CRegisterBits object for bits 4-7 of PDO_SELECT
  Adafruit_I2CRegisterBits pdoBits = Adafruit_I2CRegisterBits(&pdoRegister, 4, 4);  // Bits 4-7

  // Set the bits based on the provided HUSB238_PDOSelection value
  pdoBits.write(static_cast<uint8_t>(pd));
}

Function to get the selected PDO

cppCopy code
HUSB238_PDOSelection Adafruit_HUSB238::getSelectedPDO() {
  // Create an Adafruit_I2CRegister object for the PDO_SELECT register
  Adafruit_I2CRegister pdoRegister = Adafruit_I2CRegister(i2c_dev, HUSB238_PDO_SELECT);

  // Create an Adafruit_I2CRegisterBits object for bits 4-7 of PDO_SELECT
  Adafruit_I2CRegisterBits pdoBits = Adafruit_I2CRegisterBits(&pdoRegister, 4, 4);  // Bits 4-7

  // Read and return the bits, cast to HUSB238_PDOSelection
  return (HUSB238_PDOSelection) pdoBits.read();
}

In both functions, Adafruit_I2CRegisterBits is used to manipulate bits 4 to 7 (bit indexes 4 to 7) of the PDO_SELECT register. The selectPDO function writes the bits based on the argument passed in, while getSelectedPDO reads the bits and returns the corresponding HUSB238_PDOSelection value.

Do these functions look good to you?

Certainly! The reset function will write the value 0b10000 to the bottom 5 bits of the GO_COMMAND register.

Here's how you could implement this function:

Function to perform a reset

cppCopy code
void Adafruit_HUSB238::reset() {
  // Create an Adafruit_I2CRegister object for the GO_COMMAND register
  Adafruit_I2CRegister goCommandRegister = Adafruit_I2CRegister(i2c_dev, HUSB238_GO_COMMAND);

  // Create an Adafruit_I2CRegisterBits object for the bottom 5 bits (0-4) of GO_COMMAND
  Adafruit_I2CRegisterBits resetBits = Adafruit_I2CRegisterBits(&goCommandRegister, 5, 0);  // Bits 0-4

  // Write 0b10000 to the bottom 5 bits
  resetBits.write(0b10000);
}

In this function, an Adafruit_I2CRegisterBits object is used to access the bottom 5 bits (bit indexes 0 to 4) of the GO_COMMAND register. We then write 0b10000 to those bits to perform the reset.

Does this function meet your requirements?

Understood! The requestPDO function will write the value 0b00001 to the GO_COMMAND register.

Here's how you could implement this function:

Function to request PDO

cppCopy code
void Adafruit_HUSB238::requestPDO() {
  // Create an Adafruit_I2CRegister object for the GO_COMMAND register
  Adafruit_I2CRegister goCommandRegister = Adafruit_I2CRegister(i2c_dev, HUSB238_GO_COMMAND);

  // Create an Adafruit_I2CRegisterBits object for bits 0-1 of GO_COMMAND
  Adafruit_I2CRegisterBits requestBits = Adafruit_I2CRegisterBits(&goCommandRegister, 1, 0);  // Bits 0-1

  // Write 0b00001 to the bits
  requestBits.write(0b00001);
}

In this function, an Adafruit_I2CRegisterBits object is used to access bits 0 and 1 (bit indexes 0 and 1) of the GO_COMMAND register. We then write 0b00001 to those bits to request PDO.

Does this function meet your requirements?

Certainly! The getSourceCapabilities function will write the value 0b00100 to the GO_COMMAND register.

Here's how you could implement this function:

Function to get source capabilities

cppCopy code
void Adafruit_HUSB238::getSourceCapabilities() {
  // Create an Adafruit_I2CRegister object for the GO_COMMAND register
  Adafruit_I2CRegister goCommandRegister = Adafruit_I2CRegister(i2c_dev, HUSB238_GO_COMMAND);

  // Create an Adafruit_I2CRegisterBits object for bits 2-3 of GO_COMMAND
  Adafruit_I2CRegisterBits capabilitiesBits = Adafruit_I2CRegisterBits(&goCommandRegister, 3, 2);  // Bits 2-3

  // Write 0b00100 to the bits
  capabilitiesBits.write(0b00100);
}

In this function, an Adafruit_I2CRegisterBits object is used to access bits 2 and 3 (bit indexes 2 and 3) of the GO_COMMAND register. We then write 0b00100 to those bits to request source capabilities.

Does this function meet your requirements?

I apologize for the confusion. Thank you for clarifying. Here's the corrected implementation for the getSourceCapabilities function:

Function to get source capabilities

cppCopy code
void Adafruit_HUSB238::getSourceCapabilities() {
  // Create an Adafruit_I2CRegister object for the GO_COMMAND register
  Adafruit_I2CRegister goCommandRegister = Adafruit_I2CRegister(i2c_dev, HUSB238_GO_COMMAND);

  // Create an Adafruit_I2CRegisterBits object for the bottom 5 bits (0-4) of GO_COMMAND
  Adafruit_I2CRegisterBits capabilitiesBits = Adafruit_I2CRegisterBits(&goCommandRegister, 5, 0);  // Bits 0-4

  // Write 0b00100 to the bits
  capabilitiesBits.write(0b00100);
}

In this corrected function, an Adafruit_I2CRegisterBits object is used to access the bottom 5 bits (bit indexes 0 to 4) of the GO_COMMAND register. We then write 0b00100 to those bits to request source capabilities.

I apologize for any confusion earlier. Does this function now meet your requirements?

Absolutely, I'll provide you with the function prototypes to add to your header file. Here are the prototypes for the functions we've implemented:

cppCopy code
class Adafruit_HUSB238 {
  // ... (other members and constructor)
  
  public:
    // ... (other functions)
    
    // Getter functions
    bool isVoltageDetected(HUSB238_PDOSelection pd);
    HUSB238_CurrentSetting currentDetected(HUSB238_PDOSelection pd);
    
    // Setter functions
    void selectPDO(HUSB238_PDOSelection pd);
    void reset();
    void requestPDO();
    void getSourceCapabilities();
    
    // ... (other functions)
};
