最近收到一块STM32H7A3 NUCLEO
安装MDK 的支持库，下载stm32cubeh7工程实例
1. MDK 支持包下载
keil 支持包
https://keilpack.azureedge.net/pack/Keil.STM32H7xx_DFP.2.6.0.pack
这个下载好费劲，网络特慢，下了第6次才下载完成，下次有空放在百度云上
stm32cubeh7 库以及demo
https://www.st.com/zh/embedded-software/stm32cubeh7.html
环境安装完成
简单的修改工程，LED1 亮状态，LED2 1s钟闪烁一次

- handled in milliseconds basis.
