This experiment uses TIM5_CH1 to do input capture, we will capture the PA0 high level pulse width, and the pulse width time through the serial port print out, we can press the WK_UP button, analog input high level. At the same time, this experiment will keep on an experimental PWM output, DS0 or by dark bright -- > cycle changes, you can connect PA0 and PB5 by DuPont line, high level time to observe the output of PWM.
