TIM2、TIM3两个定时器一起配置中断,无法实现。
但配置TIM2的NVIC则不会出错,但加上TIM3的NVIC则会出错。
TIM2配置
[mw_shl_code=c,true]void TIM2_Config(void)
{
TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;
printf("
TIM2_CONFIG_IN!
");
RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM2,ENABLE);
TIM_DeInit(TIM2);
TIM_TimeBaseStructure.TIM_Period = 7199;
TIM_TimeBaseStructure.TIM_Prescaler = 39;
TIM_TimeBaseStructure.TIM_ClockDivision = TIM_CKD_DIV1;
TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
TIM_TimeBaseInit(TIM2,&TIM_TimeBaseStructure);
TIM_ClearFlag(TIM2, TIM_FLAG_Update);
TIM_ITConfig(TIM2,TIM_IT_Update|TIM_IT_Trigger,ENABLE);//
TIM_Cmd(TIM2, ENABLE);
printf("
TIM2_CONFIG_OK!
");
}
void TIM2_NVIC(void)
{
NVIC_InitTypeDef NVIC_InitStructure;
printf("
TIM2_NVIC_IN!
");
NVIC_InitStructure.NVIC_IRQChannel=TIM2_IRQn;
NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority=1;
NVIC_InitStructure.NVIC_IRQChannelSubPriority=1;
NVIC_InitStructure.NVIC_IRQChannelCmd=ENABLE;
NVIC_Init(&NVIC_InitStructure);

TIM3配置
[mw_shl_code=c,true]void TIM3_NVIC(void)
{

NVIC_SetVectorTable(NVIC_VectTab_FLASH,0x0);

NVIC_Init(&NVIC_InitStructure);
}
void TIM3_GPIO_Config(void)
{
GPIO_InitTypeDef GPIO_InitStructure;
//?????¨?±?÷3???±??
RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM3,ENABLE);
//????PINA,PINB???±??
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA,ENABLE);
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOB,ENABLE);
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_6|GPIO_Pin_7;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_Init(GPIOA,&GPIO_InitStructure);
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0;
GPIO_Init(GPIOB,&GPIO_InitStructure);
printf("
TIM3 GPIO OK
");
}
void TIM3_Mode_Config(void)
{
TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;
TIM_OCInitTypeDef TIM_OCInitStructure;
printf("
TIM3_MODE_IN!
");
TIM_TimeBaseStructure.TIM_Period = 35999;
TIM_TimeBaseStructure.TIM_Prescaler = 39;
TIM_TimeBaseStructure.TIM_ClockDivision = TIM_CKD_DIV1;
TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
TIM_TimeBaseInit(TIM3,&TIM_TimeBaseStructure);
//????TIM3??????
TIM_ClearFlag(TIM3, TIM_FLAG_Update);
TIM_ITConfig(TIM3,TIM_IT_Update|TIM_IT_Trigger,ENABLE);
TIM_Cmd(TIM3, ENABLE);
TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM1;
TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
TIM_OCInitStructure.TIM_Pulse = servox_pulse;
TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;

TIM_OC3Init(TIM3, &TIM_OCInitStructure);
TIM_OC3PreloadConfig(TIM3, TIM_OCPreload_Enable);
// TIM_ARRPreloadConfig(TIM3, ENABLE);
/* TIM3 enable counter */
printf("
TIM3 MODE OK
");
}[/mw_shl_code]
麻烦各位帮我看一下,谢谢!

去掉Printf,没有解决问题哦。
--------------------------------求分享错误程序,我当时重新写了一个绕过去了。。还不知道哪里错了
