◆ McciBootloader_Stm32L0Interface_initI2cBus()

size_t  sizeForBus,
const McciBootloaderDeviceI2cBusStm32l0_Config_t *  pConfig,
uint32_t  timingr100k,
uint32_t  timingr400k,
uint32_t  timingr1M 
)

Initialize an I2C bus controller driver on an STM32L0.

Parameters
pRamForBusPointer to a block of RAM to be used for the driver instance data
sizeForBusSize of the block of RAM. The driver checks this against the required size (must be >= sizeof(McciBootloaderDeviceI2cBusStm32l0_t))
pConfigConfiguration of the I2C block; selects the controller, etc.
timingr100kValue to use in timing register for 100kHz I2C operations
timingr400kValue to use in timing register for 400kHz I2C operations, or MCCI_BOOTLOADER_STM32L0_I2C_TIMINGR_NOT_SUPPORTED
timingr1MValue to use in timing register for 1MHz I2C operations, or MCCI_BOOTLOADER_STM32L0_I2C_TIMINGR_NOT_SUPPORTED
Returns
pointer to initialized McciBootloaderDeviceI2cBus_t object.

For simplicity, the details of the pin mapping for the I2C I/O pins is left to the caller to control. Please set up the pins prior to using the bus.

This funcion does an implicit device begin on the initialized bus.

I2C device node methods.

I2C device nodes are the equivalent of Windows PDOs; they are drivers, but they exist to export device-specific functionality from the parent bus driver to the function driver that uses the specific I2C device. Thus, we can null out the method functions as the framework behavior is sufficient.
