1. Function description

	/* Briefly describe the project function */
         This routine configures and demonstrates how to use SysTick


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

	/* Describe related module configuration methods; for example: clock, I/O, etc. */
         SystemClock: 64MHz
         USART: TX - PA9, RX - PA10, baud rate 115200
         SysTick: 10ms interrupt

	/* Describe the test steps and phenomena of the Demo */
         1. After compiling, download the program to reset and run;
         2. Start counting after the SysTick interrupt is triggered, and print information when the count is even;
