但第一个函数使用正常能够实现可变的占空比的PWM输出，但第二个函数就不能工作的，这个是什么原因呢？

Once the output pins are set up for PWM, they will cheerfully continue to output the signal for as long as you like. The duty cycle of the signal can be changed at any time. The STM32 timers There is a great variety of timers on the STM32 processors. ST application noteAN4013has a...
