Hardware Connection
The OpenH743I-C is an STM32 development board with STM32H743IIT6 as the main controller chip, which comes with a rich expansion interface to support access to various peripheral modules.
Play with your STM32 transformers, gather your Cortex-M0 / M3 / M4 / M7 team, build your embedded front, and create your electronic kingdom! Start here!
The limitation of most development boards on the market is that they are not open and modular enough, thus limiting their portability, extensibility, and application.
In fact, hardware development systems can learn from the design philosophy of software engineering - openness, modularity, and interface. So that it has "portability", "easy to expand" and other advantages so that it can be designed once and used everywhere, just like software.

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
