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。文章来源:https://www.toymoban.com/news/detail-828526.html
- 🔖 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. 启动按键文章来源地址https://www.toymoban.com/news/detail-828526.html
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();
