Hello, all!

I bought raspberry pi chip and installed raspbian stretch lite on it. The most commonly languages used for raspberry Pi are Python or C ++ language. I can write and run c++ program on raspberry pi and desktop PC. I want to understand how do we access GPIO of Raspberry in C++ language. I have searched a lot on internet before posting to question on forum but I don't understand how to access the Raspberry Pi's GPIO in C++ programming language.

I am very interested to know how do you access the Raspberry Pi's GPIO in C++ programming language. Please share your experience. Your advice can help me a lot.

 

Have you tried asking in the Raspberry Pi forums? You'll probably get the quickest answer there.

 

Are you sure you did a good searching? There's plenty of information in the web about it. Anyways, as @OBW0549 said, you can ask in the Raspberry Forums. Some of them will tell you to use the WiringPi Library, which is a PIN based GPIO access library written in C/C++ for Raspberry.

 

Welcome to AAC!

A quick search turned up this example of using the sysfs interface from C++

It starts by showing how to control GPIOs from the Shell.

There was a reference to using the GPIO registers instead, but I didn't see any examples of how it was done. If you find them, kindly post a reference; I'm trying to figure out how to do this on a different ARM based SBC.
