Detailed Description

This file provides a set of firmware functions to manage LEDs, push-buttons and COM ports available on STM32H743I-EVAL evaluation board(MB1219) from STMicroelectronics.

Author:

MCD Application Team

Version:

V1.0.0

Date:

21-April-2017

            This driver requires the stm32h743i_eval_io.c/.h files to manage the
            IO module resources mapped on the MFX IO expander.
            These resources are mainly LEDs, Joystick push buttons, SD detect pin,
            USB OTG power switch/over current drive pins, Audio
            INT pin
