1. Function description
     1. TIM3 CH2 capture pin calculates the duty cycle and frequency through the falling edge of CH1 and the rising edge of CH2
2. Use environment
	Software development environment: KEIL MDK-ARM V5.34.0.0
    Hardware development environment:
         N32G05x series:
            Developed based on the evaluation board N32G05xRBQ7_STB V1.0
         N32G05x series:
            Developed based on the evaluation board N32G05xRBL7_STB V1.0
3. Instructions for use
    System Configuration;
        1. Clock source:
                    HSI=8M,SYS CLK=64M,TIM3 CLK=64M
         2. Interruption:
                     TIM3 CC2 compare interrupt is turned on
         3. Port configuration:
                     PA8 is selected as TIM3 CH2 input
                     PA3 is selected as IO output
         4. TIM:
                     TIM3 CH1 falling edge captures CH2 signal, CH2 rising edge captures CH2 signal
     Instructions:
         1. After compiling, open the debug mode, connect PA3 and PA8, and add Frequency and DutyCycle to the watch window
         2. After the program runs, the pulse data sent by PA3 can be captured to the duty cycle and frequency to the variable
4. Matters needing attention
     The maximum interval time that can be captured by this demo is 65536*TIM3_CLK
