使用C ++处理GPIO按钮事件 [英] Handle GPIO Button event with C++

问题描述

我需要一些帮助.我正在ARM中制作一个c ++嵌入式应用程序.我需要获得一个按钮事件，我正在互联网上寻找，发现最好的方法是打断时间.我知道我可以通过终端设置一个针脚，例如回声升高>/sys/.../gpio/gpio81/edge".但是我需要知道如何在发生问题时从C ++应用程序中获取中断，我只需要一些示例，因为我不知道是否必须使用一些特殊的库.

Hi guys I need some help. I am making a c++ embedded application in an ARM. I need to get a push button event, I was looking for in internet and I find that the best way to do it is with interruptions. I know that I can set one pin through terminal like this "echo raise > /sys/.../gpio/gpio81/edge". But I need to know how can I get the interrupt from my C++ application when it happend, I just need some example, because I do not know if I have to use some special library.

谢谢你们，我希望有人能帮助我.
