3、使用说明
    系统配置；
        1、时钟源：HSI+PLL
        2、系统时钟频率：
            M7核: 600MHz
        3、中断：
			GTIMA2 CC2比较中断打开
        4、端口配置：
			PA7选择为GTIMA2 CH2输入
			PA3选择为IO 输出
        5、TIM：
			GTIMA2_CH1下降沿捕获CH2信号，CH2上升沿捕获CH2信号
    使用方法：
        1、编译后打开调试模式，连接PA3与PA7，将Frequency、DutyCycle添加到watch窗口
        2、程序运行后，PA3发送的脉冲数据可以被捕获到占空比和频率到变量

4、注意事项
    无

            M7 Core:     600MHz
        3. Interruption:
			GTIMA2 CC2 compare interrupt is turned on
        4. Port configuration:
			PA7 is selected as GTIMA2_CH2 input
			PA3 is selected as IO output
        5. TIM:
			GTIMA2_CH1 falling edge captures CH2 signal, CH2 rising edge captures CH2 signal
     Instructions:
         1. After compiling, open the debug mode, connect PA3 and PA7, 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. Attention
    None
