STM32定时器的基本应用，PWM的的输入捕获，硬件调试通过，基本没有误差。 -The basic application of the STM32 timer, PWM input capture hardware debugging through, basically there is no error.

用于一些单片机产生的pwm输入捕捉，进行一些计算脉冲数。这是公司外面请人编写的，代码可以正常运行-Used for some microcontroller to generate the pwm input capture, to calculate the number of pulses. This is written outside the company, the code can be normal operation
