如果知道频率是100hz，自动重装载值和预分频系数是怎么算出来的呢？


void TIM6_Configuration(unsigned int TIM_Period,unsigned int TIM_Prescaler)
{
  TIM_TimeBaseInitTypeDef TIM_TimeBaseStruct;
       
        RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM6,ENABLE);
        RCC_APB2PeriphClockCmd(RCC_APB2Periph_AFIO,ENABLE);
       
        TIM_TimeBaseStruct.TIM_Period=1799;//初值
        TIM_TimeBaseStruct.TIM_Prescaler=9;//预分频
        TIM_TimeBaseStruct.TIM_ClockDivision=0;
        TIM_TimeBaseStruct.TIM_CounterMode=TIM_CounterMode_Up;//向上

        TIM_TimeBaseInit(TIM6,&TIM_TimeBaseStruct);
//        TIM_ClearFlag(TIM6,TIM_IT_Update);
        TIM_ITConfig(TIM6,TIM_IT_Update,ENABLE);
       
//        TIM_Cmd(TIM6,ENABLE);
}

void NVIC_Tim6_Configuration(void)
{
  NVIC_InitTypeDef NVIC_InitStructure;

        NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);

        NVIC_InitStructure.NVIC_IRQChannel = TIM6_IRQn;
        NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 2;
        NVIC_InitStructure.NVIC_IRQChannelSubPriority = 2;
        NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
        NVIC_Init(&NVIC_InitStructure);
}
