OpenH743I-C User Guide

Instruction

This developer Kit is the new member of Open series, its core board is based on STM32H743IIT6.Interfaces are expended for easy using.

About the examples

We provide demo code for you to follow.The demo codes use HAL libraries, generated by STM32CubeMX v5.0, edited by KEIL MDK v5.12. The firmware libraries of STM32H7 used is v1.3.2

Preparation

• Programmer: ST-Link V2
• Programming Inteface: JTAG/SWD
• You should use Serial assistance software to check output if the examples use serial print. OpenH743I-C integrate CP2102 chip on board, you just need to connect USART1 interface to PC by USB cable, and remove the OTG_JMP jumper, hereafter will no longer describe this setting。
• The parameters of serial port should be: (Serial assistant software)

Baud rate	115200
Data bit	8
Stop bit	1
Parity bit	None
Flow Ctl	None

【Note】You should pres reset button to run the code after programming.
