HAL STM32通过multi_button库处理按键事件

📍作者：0x1abin的multi_button库:https://github.com/0x1abin/MultiButton

📘MultiButton简介

MultiButton 是一个小巧简单易用的事件驱动型按键驱动模块，可无限量扩展按键，按键事件的回调异步处理方式可以简化你的程序结构，去除冗余的按键处理硬编码，让你的按键业务逻辑更清晰。

🔖 该库驱动代码纯C语言实现，可以移植到任意需要使用的地方。

🔑使用方法

先申请一个按键结构

struct Button button1;

初始化按键对象，绑定按键的GPIO电平读取接口read_button_pin() ，后一个参数设置有效触发电平。

button_init(&button1, read_button_pin, 0, 0);//绑定按键，读取按键引脚状态，有效触发电平、按键ID

注册按键事件

button_attach(&button1, SINGLE_CLICK, Callback_SINGLE_CLICK_Handler);
button_attach(&button1, DOUBLE_CLICK, Callback_DOUBLE_Click_Handler);

…
4. 启动按键

button_start(&button1);

设置一个5ms间隔的定时器循环调用后台处理函数

while(1) {...if(timer_ticks == 5) {timer_ticks = 0;button_ticks();}
}

🛠按键引脚配置

🌿通过STM32CubeMX，将按键引脚配置成上拉，那么有效触发电平就需要设置为0.

📗通过按键事件查询，获取按键状态

🌿在滴答定时器中断函数（SysTick_Handler）中添加button_tick();
