     Instructions:
        1. After compilation, download the program to the development board and reset it to run.
        2. Check the serial port printing. If the serial port is printed "runing" , not printed and there is an error, 
           it indicates that it is running normally.


4. Attention
    1. Connect jump caps J8/J2/J15/J9, do not connect jump caps J87/J89
    2. N32H497ZGL7-EVB V1.0 board requires soldering two 120 Ω resistors, R26 and R41
