GPIO with sysfs on Raspberry Pi (Part 2)

In my last post on using sysfs for GPIO on Raspberry Pi, I showed you how you can use the sysfs file system to manipulate the state of the GPIO pins. This time, we’re going to explore how to do the same thing programmatically. I’m going to walk you through developing a C library to […]

GPIO with sysfs on a Raspberry Pi

The Raspberry Pi (in case you’ve been living under a rock for the last six-months) is a cheap ($25) ARM Linux computer, primarily designed to be used to help teach kids to learn programming & computer science. It’s also makes a pretty nice alternative to something like a BeagleBone, if you’re looking to play with […]
