                             Sample Description
================================================================================
功能描述：
此样例演示了OPA转换为COMP的功能,PA7为正端,PC5为负端,当PA7的电压值大于PC5的电压值，
进入中断,LED灯亮。

Function descriptions:
This example demonstrates the function of converting OPA to COMP, with PA7 as 
the positive terminal and PC5 as the negative terminal. When the voltage value 
of PA7 is greater than that of PC5,Enter interrupt, LED light on.
