STMicroelectronics AN2500 Application Note

About this manual

This document describes a set of API functions included in the ST10 electric motor control library. These functions simplify the usage of the MP49 motor control power board by providing ST10 compatible SPI drivers for configuration and diagnostic purposes.

The communication between the CPU board and the MP49 motor power board is based on an SPI interface. The note details the SPI interface signals, the specific commands used for configuration and diagnosis, and the fault detection interface that reports system errors.
