NULLCape. How to Roll your own BeagleBone Capes (Part IV)

If you have been following this tutorial, you should have a fully functional NULLCape. Probably, you would also be thinking: "Yes, that's right, but this NULLCape is useless". And you are completely right... However, this can be easily improved with just some wires... Keep reading to know how.

NULLCape. How to Roll your own BeagleBone Capes (Part I)

We want to learn how to build BegleBone capes and in this series of post we will be writing about our findings and how we built the NULLCape. You are right, that is the very minimum cape which actually does nothing.

BUT..., WHAT IS A CAPE AFTER ALL?

Good question. Yes, sure you already now, but just in case you are really, really new to the BeagleBone or you've got yours as a present you had never ever hear of it.

A cape is just an expansion board for the BeagleBone. The BeagleBone provides two headers on its sides with lots of signals and interfaces, however you normally need something else to be able to attach your peripherals to this connectors. In the simpler case some wires and a platform to mechanically keep your peripheral and in the most complex case some support circuitry in order to do whatever you want to do.
