BeagleBone Black programmable realtime unit (PRU) Hello World – Part 2

Introduction

In this part of the series I’m going to show you how to write a very basic C Host-Application that will run a program on the PRU of the BBB. This part of the series assumes that you have basic C skills. I’ll also include some useful links to the official ti API. Everything can be done with the tools that come with the BBB. Code Composer Studio (CCS) oder Eclipse are not needed needed but you can use them, if you want to.

But I soon realized that this is absolutely not a fun topic to start with, especially, if you are new to programming or embedded architectures. PRU programming can be pretty frustrating in the beginning and there is almost no community support or tutorials. But I’ll try to cover the topic as good as I can. Let’s get started!
