I've been using micro-controllers with my fischertechnik models but wanted to go inside the Embedded Computing world and learn I²C protocol.

So I started with an Arduino with four main goals:

1. Go inside of a micro-controller because the fischertechnik Robo TX Controller is a very nice but rather closed black box,
2. Get a better understanding of the embedded programming requirements,
3. Get familiar with I²C protocol and experiment with I²C sensors and actuators,
4. Try and communicate with fischertechnik Robo TX Controller through opto-couplers, digital potentiometer and finally I²C to design my own smart devices.

After a while, I went 32-bit with the powerful chipKIT Uno32 board. Later on came the Wiring S and the 16-bit lower-power LaunchPad boards, the 32-bit LeafLabs Maple and finally the 32-bit ARM-based LaunchPads. 

Looking for a more advanced IDE, I've developed embedXcode, a template for Xcode that supports the most popular Processing-based Wiring-derived Arduino-like boards.

Among the major projects, I'm focusing on screens, starting with a GPU-based screen and then standard SPI and parallel screens as well as other promising ultra-low power technologies like memory display and e-paper. I'm ​also exploring the Internet of Things.
