                             Sample Description
================================================================================
功能描述：
此样例演示了CRC校验功能，通过对一个数组里的数据进行校验，得到的校验值与理论校验
值进行比较，相等则LED灯亮，否则LED灯熄灭。

Function descriptions:
This sample demonstrates the CRC verification function. It performs a CRC 
check on an array of data and compares the obtained checksum with the expected 
checksum. If they are equal, the LED lights up; otherwise, the LED turns off.

测试环境：
测试用板：PY32MD310_STK
MDK版本： 5.28
IAR版本： 9.20
GCC版本： GNU Arm Embedded Toolchain 10.3-2021.10

Test environment:
Test board: PY32MD310_STK
MDK Version: 5.28
IAR Version: 9.20
GCC Version: GNU Arm Embedded Toolchain 10.3-2021.10
================================================================================
使用步骤：
1. 编译下载程序到MCU，并运行；
2. 观察LED灯是否亮起，如果灯亮表示运行成功，否则运行失败

Example execution steps:
1.Compile and download the program to the MCU and run it.
2.Observe whether the LED lights up. If the LED is on, it indicates successful 
execution; otherwise, it indicates a failure.
