TIM2，采用timing模式，不能进入中断 [复制链接]

TIM2的输入比较，为什么模式选择 timing就进不了中断

如题，我的程序如下： 当 TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_Timing;时，不能进入中断，但是如果改成其他模式就可以   void TIM2_Configuration(void) {   TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;       TIM_OCInitTypeDef TIM_OCInitStructure;  RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM2 ,ENABLE);        TIM_TimeBaseStructure.TIM_Period = 65535;     TIM_TimeBaseStructure.TIM_Prescaler = 0;        TIM_TimeBaseStructure.TIM_ClockDivision = 0x0;  TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;  TIM_TimeBaseInit(TIM2, & TIM_TimeBaseStructure);  TIM_PrescalerConfig(TIM2, 4, TIM_PSCReloadMode_Immediate);         TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_Timing;  TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;     TIM_OCInitStructure.TIM_Pulse = 32768;                    TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;  TIM_OC2Init(TIM2, & TIM_OCInitStructure);  TIM_OC2PreloadConfig(TIM2, TIM_OCPreload_Disable);      TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;  TIM_OCInitStructure.TIM_Pulse = 16384;  //TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;  TIM_OC3Init(TIM2, & TIM_OCInitStructure);  TIM_OC3PreloadConfig(TIM2, TIM_OCPreload_Disable);   //不使能预装载寄存器  TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;  TIM_OCInitStructure.TIM_Pulse = 8192;  //TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;  TIM_OC4Init(TIM2, & TIM_OCInitStructure);  TIM_OC4PreloadConfig(TIM2, TIM_OCPreload_Disable);   //不使能预装载寄存器     TIM_ITConfig(TIM2,TIM_IT_CC2|TIM_IT_CC3|TIM_IT_CC4,ENABLE);     /* TIM2 enable counter */     TIM_Cmd(TIM2, ENABLE);//开启时钟

我在用TIM2做输出比较时，也就是按照keil 安装目录下的ST的timebase例子实验，发现不能进入中断，可是如果把模式改为PWM1或Toggle就可以进入

没有人遇到过吗

发现问题了，其实没有什么问题，主要是用keil仿真看不到波形，用示波器看了看，还是有波形的。

是用示波器在定时器2配置的输出引脚上看的吗？不是说TIM_OCMode_Timing：在比较成功时不对输出引脚的状态产生影响，适合于做定时使用吗？麻烦给一下回复啊 谢谢了 遇到这方面的问题了 急急急？？？qq:845496118

keil不能仿真管脚上的信号

最好是连接JLINK 或其他的工具，如果只是用Keil ARM软件仿真，有些功能可能不是很容易看到结果。
