STM8S TIM4库函数应用

void TIM4_TimerInit(u8 Timer4Time)

{

  assert_param(IS_TIM4TIMERTIME_OK(Timer4Time));

  TIM4_DeInit();//复位TIM4全部參数

  TIM4_TimeBaseInit(TIM4_PRESCALER_16,Timer4Time);//16M/16= 1M CYCLE=1/1=1U 100us中断一次

  //选择16分频 16M/16=1M  周期为1us

  TIM4_Cmd(ENABLE);//使能计时器

  TIM4_ITConfig(TIM4_IT_UPDATE,ENABLE);//使能TIM4中断

}

初始化时，调用：

TIM4_TimerInit(125)//定时125us中断一次
