T'rex motor controller HELP!

Please help!!!!

My team and I are using the T'rex chassis and motor controller from Dagu. We would like to have the Arduino Due control the motor controller through I2C. However, we have been having problems. If we load the code provided from Dagu for I2C it works for an Arduino Mega but no joy on the Arduino Due. We know there are differences but have been unable to figure out what they are (libaries, pins, etc). I was able to modify the code and it now compiles and loads on the Due, but I am now receiving the following error:

Master Command Data Packet Sent

0 wrong start byte

I've checked the code and it's set to 0x0F. Any help would be greatly appreciated....thanks everyone.

There is also a thread started by OddBot, the designer of the TRex controller that might answer you question.

The TRex is an Arduino with a built in motor controller, or perhaps the other way around.
