                                样例使用说明
                             Sample Description
================================================================================
功能描述：
此样例演示了COMP比较器中断功能，PA04作为比较器负端输入，1/2VCCA 作为正端输入，通
过调整PA04上的输入电压，当检测到比较器输出状态为高时，LED灯亮，比较器输出状态为
低时，LED灯灭。

Function descriptions:
This example demonstrates the COMP comparator interrupt function, with PA04 as 
the negative input of the comparator and 1/2VCCA as the positive input. By 
adjusting the input voltage on PA04, when the comparator output state is detected
to be high, the LED light will turn on, and when the comparator output state is 
low, the LED light will turn off.

测试环境：
测试用板：PY32M010_STK
MDK版本： 5.28

Test environment:
Test board: PY32M010_STK
MDK Version: 5.28
================================================================================
使用步骤：
1. 编译下载程序到MCU，并运行；
2. 配置PA04输入大于1.65V电压，LED灯灭；
3. 配置PA04输入小于1.65V电压，LED灯亮。

Example execution steps:
1. Compile and download the program to MCU and run it;
2. Configure PA04 input voltage greater than 1.65V,LED light off;
3. Configure PA04 input voltage less than 1.65V,LED light on;
================================================================================
注意事项：
如果需要使用按键:
StartKit版本为V1.0,需将StartKit.h中的StartKitVersion 2 注释掉，并打开
StartKitVersion 1
StartKit版本为V1.0以上版本,则无需操作

Notes:
If you need to use buttons:
StartKit version is V1.0, please comment out StartKitVersion 2 in StartKit.h and 
open StartKitVersion 1
If the StartKit version is above V1.0, no operation is required
