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, an Italian designed 8-bit micro-controller. The four main goals were:

1. Go inside of a micro-controller because the fischertechnik Robo TX Controller is a very nice box but rather closed black box,
2. Understand the embedded programming better,
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.

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, and finally the 32-bit LeafLabs Maple. 

Looking for a more advanced IDE, I developed embedXcode, a template for Xcode that supports all the Processing-based Wiring-derived boards.

I've also explored the touch screens, starting with the μLCD-32PT(SGC) 3.2” display module, and eventually released the Serial_LCD Library Suite for all the μLCD, μOLED and μVGA screens from 4D Systems.
