Detailed Description

Platform-independent bus interface.

Sensor drivers include NEITHER HAL nor RTOS: they only receive these function pointers. The same library therefore runs on STM32 (HAL binding, see bsp/imu_i2c.c), on another MCU, or on a PC with a simulated bus.

bus_write_fn

typedef int32_t(* bus_write_fn) (void *handle, uint8_t reg, const uint8_t *data, uint16_t len)

All functions return 0 on success, != 0 on error.
