教你使用RT-Thread开启STM32H7系列的RTC与Alarm组件

STM32

背景

【ART-PI】默认没有开启Alarm组件，尝试适配并开启
有部分工程师想使用RT-Thread 基于STM32H7系列的RTC 与 Alarm（闹钟功能）

验证平台

Keil MDK5（使用RT-Thread Studio 可以作为参考）
【ART-PI】STM32H750XBH6，使用Pandoro STM32L4系列MCU，同样验证通过

移植方法

只前做过一次基于Apollo3平台的Alarm组件的移植，适配部分与STM32有些不同，直接Copy过去编译，发现编译不过，很正常！！
这次基于STM32H7、STM32L4平台，如果也编译不过去，只需要微调！
