3. Instructions for use
    System Configuration;
        1. Clock source:
                    HSI=8M,SYS CLK=64M,TIM1 CLK=64M,TIM3 CLK=64M,TIM4 CLK=64M
        2. Port configuration:
                    PA4 is selected as TIM1 CH1 output
                    PA6 is selected as TIM1 CH2 output
                    PA8 is selected as TIM3 CH1 output
                    PB6 is selected as TIM4 CH1 output
         3. TIM:
                     TIM1 CH2 gated TIM1 CH1, gated TIM3 CH1.TIM3 gated TIM4 CH1
     Instructions:
         1. After compiling, turn on the debug mode, use an oscilloscope or logic analyzer to observe the waveforms of TIM1 CH1, TIM3 CH1, TIM4 CH1
         2. TIM1 CH2 high level timer starts counting, low level stops
4. Matters needing attention
