怎么将引脚配置为动态输入或输出

嗨，我正面临一个问题，同时动态配置IO引脚作为输入或输出。我正在使用PLIB库。这是我的代码序列。首先，我使用：PLIB_SetDirectionOutput函数设置pin的方向作为输出。然后使用PLIB_PinClear函数清除pin。我认为pin clear函数设置pin作为输入。然后再次使用PLIB_SetDirectionOutput函数设置特定的pin作为输出。然后我使用有趣地将相同的pin设置为高。ctionPLIB_PinSet函数。但当我连接这些管脚到输出管脚时，我无法读取其他输入管脚的状态。这里我做错了什么？请帮帮我。谢谢。

    Hi.
I am facing an issue while dynamically configuring the IO pin as input or output. I am using PLIB library. Here is the sequence of my code.

First I set direction of pin as output using:
PLIB_SetDirectionOutput function.
Then clear the pins using
PLIB_PinClear function.

I think pin clear function sets the pin as input.

Then again u set particular pin as output using
PLIB_SetDirectionOutput function.

Then I set the same pin as high by using function
PLIB_PinSet function.


But I am not able to read the state in other input pins when I am connecting these pin to output pin.
What am I doing wrong here. Please help me.

Thanks
