Unfortunately, it means that the Leonardo cannot be used with the AFMotor library. The Leonardo uses an ATmega32U4 chip, which has a different arrangement of timers and pins than the ATmega328 used in the UNO. The AFMotor library has not been written to work with the 32U4.

Is anyone working on porting a library for the Leonardo?

[adafruit_support_rick]

We are in the process of porting our libraries to Leonardo and Due. Offhand, I can't say whether or not the motor shield is even compatible with Leonardo, due to the different pin mappings for the timers. I'll have to investigate that.

[adafruit_support_rick]

I just checked the timer pinouts, and it looks like it ought to be possible to port the library to Leonardo. No time frame for that, however.

Michael Margolis has produced a version of the AFMotor library to accompany his book on using the Arduino for robotics.

The publisher of the book has made the library available as part of this download:
