利用stm32f103的TIM2实现精确延时
void TIM_ResetCounter(TIM_TypeDef * TIMx){TIMx->CNT = 0;}void TIM2_Delay_ms(unsigned int cms){unsigned short temp = 0;TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;TIM_TimeBaseStructInit(&TIM_TimeBase
void TIM_ResetCounter(TIM_TypeDef * TIMx){TIMx->CNT = 0;}void TIM2_Delay_ms(unsigned int cms){unsigned short temp = 0;TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;TIM_TimeBaseStructInit(&TIM_TimeBase
