void tiM3_Configuration(void)
{
TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;

TIM_ClearITPendingBit(TIM3,TIM_IT_Update);

TIM_TimeBaseStructure.TIM_Period =1000;  
TIM_TimeBaseStructure.TIM_Prescaler =0;    //72mhz
TIM_TimeBaseStructure.TIM_ClockDivision =0;
TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
TIM_TimeBaseInit(TIM3,&TIM_TimeBaseStructure);

TIM_ITConfig(TIM3,TIM_IT_Update,ENABLE);
TIM_Cmd(TIM3,ENABLE);

}
请问如果我这样配置定时器的话，是不是每1/72000秒触发一次中断？
谢谢！
