OddBots rover 5 encoder code

So OddBot has posted some very interesting code on his service droid page: http://letsmakerobots.com/node/39492 (see downloads revision 2 code. This should give better speed control of the motors. I have a Rover 5 with 4 motors/encoders and mecanum wheels. The wheels don't work very well, so I want the best possible speed control of the motors. I would like to convert OddBots code so it works on my ATmega1280.

Getting ready for the service droid :)

So I've ordered the Dagu service droid :) http://letsmakerobots.com/node/38776

I'm getting the service droid with a Rover 5 (4 motors/encoders), 4 channel motor controller and Dagu Red Back Spider.

I already have a Rover 5 with 4 motors on which I use the 4 channel motor controller and Red Back Spider. I'm powering everything from a 2S Lipo (3000mAh). You can see it here: http://letsmakerobots.com/node/31410 or on my blog: http://www.bajdi.com/category/rover-5/

On my current Rover 5 the 2S Lipo feeds 3 devices:
