We mainly followed this post, but used a different GPIO port, we soldered the components (once we tested the schematics on a protyping board) and modified the ...

Introduction to accessing the Raspberry Pi’s GPIO in C++ (sysfs)

Introduction In this blog entry I will demonstrate how one can access the Raspberry Pi’s GPIO in C++. There are two approaches to accomplish this. The first is to directly manipulate the Raspberry Pi’s GPIO’s registers much like one would do when programming a microcontroller without an operating system (OS) or a memory management unit (approach using mmap). The advantage of this approach is that because th ...
