一些比较好的笔记

网上有很多教程，但是原作者已经重新开发了一套，但是博客作者没有更新

本来想去找基于HAL开发MultiTimer，却让我找到一个关于HAL库Systick-系统滴答定时器详解，文章确实写的很不错

找了很久才找到一个新的教程，但是这个教程乍一看有点乱，其实细看还好，结尾还说了一些实现的原理

接下来我将我移植的步骤记录下来，作为纯开发记录


  • 移植.h 和 .c文件
    这个我相信大家都是懂的,并且在你的main.c文件中include进来

  • 在main函数开始后的初始化中，安装tick函数
MultiTimerInstall(PlatformTicksGetFunc);

  • 在main函数前面定义的地方，获取系统 tick
/* USER CODE BEGIN 0 */uint64_t PlatformTicksGetFunc(void){  return (uint64_t)HAL_GetTick();}/* USER CODE END 0 */

  • 在定义变量的地方，创建Timer对象
MultiTimer timer1;

  • 在声明函数的地方，声明Timer回调函数
void timer1_callback(MultiTimer* timer, void* userData);

  • 在函数定义的地方，实现Timer回调函数功能
void timer1_callback(MultiTimer* timer, void* userData){    HAL_GPIO_TogglePin(LED1_GPIO_Port,LED1_Pin);           　　　　　　//需要做的任务    MultiTimerStart(&timer1, test_timer1, timer1_callback, NULL);    //这里要将任务重新开始，不然函数只会执行一次，第二个参数就是定时时间，默认1000}

  • 在main函数while开始前面，启动定时器
MultiTimerStart(&timer1, 1000, timer1_callback, NULL);

  • 在主循环while中调用Timer对象处理函数
MultiTimerYield();

至此，函数已经分类实现完毕，接下来给一份完整main.c文件，作为参考
