通过 (uint16_t)(CCR1 – CCR2)，我们可以得到 低电平 ，而通过两次CCR1 或者 CCR2 的差值，我们可以得到 周期 。这样计算频率和占空比就不是什么难事了。特别需要注意的是，三次上升沿捕获期间，定时器不可以产生溢出现象，这可以通过定时器分频实现。分频系数越小，分辨率越高，但越容易溢出。

这里要注意的是，如果频率比较高，建议多测量几组数据，然后取后面几组数据进行简单平均或中值计算（具体根据捕获值来确定），这样准确度更高一些，因为刚开始可能因为初始化的缘故，导致意外捕获，这是可能的（刚开始不确定可以测个 64 组再说）。

另外如果输入 PWM 频率或占空比会 不断变化 ，也需要根据情况多测几组（或定时测），并进行简单处理，这样不容易刚好捕获到变化的脉冲，保证脉冲计算的可靠性。
