Hi Emmanuel, thanks for the fine code. It looks very nice.
The Problem is, that I always get the following Error-Message when Linking:
Method controlMotor(II)V not found in lejos/nxt/TachoMotorPort
I don't understand that error, because TachoMotorPort inherits
controlMotor(int,int):void from BasicMotorPort.
Any ideas why I get that error?
Thanks!
Michael
