A Special Filesystem? | Coding the ProcFS File System | Raspberry Pi GPIO Driver Development

In our previous video, we discussed how to create a driver for the Raspberry Pi. Doing this gave us code execution in the Kernel so that we could legally access addresses otherwise forbidden in user space. In this video, I show you all how to create an interface between the user and the drive via the procfs filesystem. Doing this allows us to access the driver and send data to it from the command line. In my next video, we finish up the driver and control the GPIO pins via our driver from the command line: all in C/C++!
