Timer 1 is connected to theAPB2, which is running at 180 MHz. Timer 2 is connected to theAPB1, which is running at 90 MHz. Below is the image showing the configuration of the TIMER 2 for Input Capture Mode. Enable the Input captureDirect Modeon channel 1. ...
这样,我们就完成一次高电平捕获了,只要 TIM5CH1_CAPTURE_STA 的第 7 位一直为 1, 那么就不会进行第二次捕获,我们在main函数处理完捕获数据后,将TIM5CH1_CAPTURE_STA 置零,就可以开启第二次捕获。 timer.h 头文件内容比较简单,主要是函数申明,这里我们不做过多讲解。 接下来,我们看看 main 函数内容: extern...
