Function Documentation

i2c_give()

void i2c_give

(

uint8_t

i2c_interface

)

Release the previously gained I2C bus.

Parameters

i2c_interface

Physical I2C bus ID

i2c_init()

void i2c_init

(

void

)

Initialize peripheral I2C buses.

This function initializes all buses listed on the i2c_mux table, configuring the controller hardware and creating a binary semaphore for each.
