These are the steps to enable I²C on Raspbian after downloading the new Raspbian “wheezy” image.

The Raspberry Pi is a interesting little computer to use in embedded projects, especially when you need something more powerfull than a common microcontroller.

In my previous post I have connected a TC74 via USB to the Raspberry Pi. It works, but I consider it a waste because the Raspberry Pi has GPIO’s available.

So, now that I have a Raspberry Pi and I can read the temperature with a TC74 over USB, I thought it would be nice to combine them together.

Below, a picture of the Raspberry Pi that I’ve received wednesday.
