STM32-DS2482-HAL

A DS2482-100 HAL for the STM32F3/F4/H7 series

Usage

Define the target chip, and set the compiler to C23+:

gcc [...] --std=gnu2x -DSTM32[F3/F4/H7]

or

# (in STM32-for-VSCode.config.yaml)
# Compiler definitions. The -D prefix for the compiler will be automatically added.
cDefinitions:
  - STM32[F3/F4/H7]
  - USE_HAL_DRIVER

# ...

# Compiler flags
cFlags: 
  - --std=gnu2x

Then, configure the HAL:

// (in DS2482_HAL.h)
#define MULTIPLE_DEVICES false   //set to true if multiple DS2482 devices are connected

#if !MULTIPLE_DEVICES
    #define DS2482_I2C_ADDR 0x00 //set to I2C address of the DS2482 device (if in single device mode)
#endif
#define DS2482_TIMEOUT_1W 100    //timeout in ms for 1-wire operations
#define DS2482_TIMEOUT_I2C 100   //timeout in ms for I2C operations

For multiple DS2482 devices on one chip:

• Set MULTIPLE_DEVICES to true
• Call ds2482_create() with the I2C handle and address
• Call ds2482_init() with the handle
• The HAL is ready

For just one DS2482:

• Set DS2482_I2C_ADDR to the I2C address
• Call ds2482_init() with the I2C handle
• The HAL is ready

Be sure to check the return values for error handling.
