STM32移植嵌入式开源按键框架

   本日移植了一款嵌入式按键框架工程MultiButton，MultiButton是一个小巧简朴易用的变乱驱动型按键驱动模块。
  Github地点：GitHub - 0x1abin/MultiButton: Button driver for embedded system
  

  现于2024.04.15举行移植，详细就两个文件：multi_button的c文件和h文件。
  
MultiButton简介

   MultiButton 是一个小巧简朴易用的变乱驱动型按键驱动模块，可无穷量扩展按键，按键变乱的回调异步处置惩罚方式可以简化你的步调布局，去除冗余的按键处置惩罚硬编码，让你的按键业务逻辑更清楚。
