原子的定时器实验如何间TIM3改成TIM1

[mw_shl_code=c,true]void TIM1_Int_Init(u16 arr,u16 psc) { TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure; NVIC_InitTypeDef NVIC_InitStructure; void TIM1_Int_Init(u16 arr,u16 psc) {   TIM_TimeBaseInitTypeDef  TIM_TimeBaseStructure; NVIC_InitTypeDef NVIC_InitStructure; RCC_APB2PeriphClockCmd(RCC_APB2Periph_TIM1, ENABLE);//这里的由APB1改成APB2 TIM_TimeBaseStructure.TIM_Period = arr; TIM_TimeBaseStructure.TIM_Prescaler =psc; TIM_TimeBaseStructure.TIM_ClockDivision = TIM_CKD_DIV1;  TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;  TIM_TimeBaseInit(TIM1, &TIM_TimeBaseStructure);   TIM_ITConfig(TIM1,TIM_IT_Update,ENABLE );  NVIC_InitStructure.NVIC_IRQChannel = TIM1_UP_IRQn;//这里由TIM3_IRQn该成TIM1_UP_IRQn NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;  NVIC_InitStructure.NVIC_IRQChannelSubPriority = 3;   NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;  NVIC_Init(&NVIC_InitStructure);   TIM_Cmd(TIM1, ENABLE);  } void TIM1_UP_IRQHandler(void)     //这是由 TIM3_IRQHandler 改成TIM1_UP_IRQHandler { if (TIM_GetITStatus(TIM1, TIM_IT_Update) != RESET)  { LED0=~LED0; TIM_ClearITPendingBit(TIM1, TIM_IT_Update  );  // LED1=!LED1; } }[/mw_shl_code]

我将原子的实验 定时器中断实验  的TIM3改成TIM1，出现现象：LED0一直亮，没有灭。定时是500ms
我只改了上面标出来的那部分代码，不知道还有哪里要给或者添加的？

正点原子

论坛有TIM1的配置，搜索下，参考别人的代码。

八度空间

TIM1是高级定时器，你好像漏了什么东西没用上

改好了   重复计数寄存器要配置成0x00,要不然定时时间比预想的要长。
