STM32H7 环境安装与DEMO测试

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

环境安装完成

简单的修改工程，LED1 亮状态，LED2 1s钟闪烁一次

         duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and

         handled in milliseconds basis.

       - Set NVIC Group Priority to 4

       - Low Level Initialization
