Chapter 1. Embedded Linux for Makers

If you’re familiar with Linux, you probably think of it firstly as a computer operating system, like OS X or Windows. It’s usually running on user desktops and powering servers. But recently, Linux can also be found within many consumer electronics devices. Whether they’re inside a cell phone, cable box, or exercise bike, embedded Linux systems blur the definition between computer and device.

This blurriness has made its way into the maker realm and that’s great because it’s putting more powerful tools in the hands of regular people, not just those who design electronics for a living.

Many makers who work with electronics love microcontroller platforms like the Arduino, but as the complexity increases in their ...
