1 第一步：使能定时器时钟，对于TIM1调用形式为RCC_APB2PeriphClockCmd(RCC_APB2Periph_TIM1, ENABLE);2 第二步：配置中断向量，TIM1比较中断的中断向量为：TIM1_CC_IRQn 3 第三步：配置并初始化基本定时器，注意计数器的计数周期不要小于比较的值。4 第四步：配置相应的比较中断的参数，如果只是想利用比较...

选择NVIC_IRQChannel中的TIM1_CC_IRQn，即TIM1捕获比较中断。
TIMG模块由16位和32位自动重新加载计数器组成,由可编程预计算器驱动,具有两个捕获/比较(CC)块,用于多个捕获/比较、PWM输出和间隔定时。TIMG还具有广泛的事件生成功能,包括计数器溢出、重加载和针对各种用例的捕获/比较操作。 1.2 定时器基本参数 1.2.1 预分频 预分频器可以将定时器的时钟(TIMCLK)频率按1到256之...
