Chapter 5. Python Pin Control

One of the strengths of embedded Linux platforms like the BeagleBone is being able to choose the programming language that suits you best. In many other cases, choosing a hardware platform means you’re also committing a particular language and development environment. That’s far from the truth with the BeagleBone. The downside to the flexibility that the BeagleBone affords is that there are many different ways to do the same thing. This chapter will walk you through one way to use code to interact with the pins on the board.

When you write code for a microcontroller like the Arduino, most of the time, you write the on your computer, compile it, and then upload the compiled binary to the microcontroller. However, on ...
