I got I2C working well a couple of weeks back and got both the modules I am using working well with the beaglebone. I later modified the code to allow API calls to read the values from the two modules. Now I have a proper working directory for the complete project and I’ve decided to test out other things separately and then import them into this single working directory.
This post is to describe how to get the I2C working on the Beaglebone. I got some help from https://github.com/quick2wire/beaglebone. The only problem was that I planned on using C/C++, not python, for better support with OpenCV. I’ll explain the protocol along with the code together. This post assumes you know a bit of electronics. Make sure you don’t connect any 5V supply to any of the beaglebone pins and don’t draw too much power. This means you should only…
