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();
