                                样例使用说明
                             Sample Description
================================================================================
功能描述：
此样例演示了ACMP的反电动势检测功能，初始化ACMP0、1、2三个通道，P端接引脚，N端接内部电
阻，使能反电动势功能后，可测量出通道之间的阻值，LED1每隔1s翻转一次。

Function descriptions:
This example demonstrates the back electromotive force detection function of ACMP, 
initializing ACMP channels 0, 1, and 2, P-terminal pin, N-terminal internal 
electrical connection After enabling the anti electromotive force function, the 
resistance value between channels can be measured, LED1 flips every 1 second.

测试环境：
测试用板：DPM32M087RBTx_EVB V1.0
MDK版本： 5.28

Test environment:
Test board: DPM32M087RBTx_EVB V1.0
MDK Version: 5.28
================================================================================
使用步骤：
1. 编译下载程序到MCU，并运行。
2. 可观察到开发板上的LED1每隔1s翻转一次。
3. 可测量ACMP两两引脚之间的阻值。

Example execution steps:
1. Compile and download the program to MCU, and run it.
2. It can be observed that LED1 on the development board flips every 1 second.
3. It can measure the resistance between two pins of ACMP.
================================================================================
注意事项：
LED引脚如下：
LED1       -> PC10

ACMP引脚如下：
ACMP_IN0   -> PA4
ACMP_IN2   -> PA6
ACMP_IN4   -> PD12

Notes:
The LED pins are as follows:
LED1       -> PC10

The UART pins are as follows:
ACMP_IN0   -> PA4
ACMP_IN2   -> PA6
ACMP_IN4   -> PD12
