I was wondering what methods of breaking have been used with handyboard motors. Is it OK just to slam them in reverse for a few milliseconds ? Or will the large current impulse be harmful to the motor and driver chips ? It looks like the breaking (...) (28 years ago, 7-Mar-97, to lugnet.robotics.handyboard)

Can anyone tell me what servo.lis has in it. I have the servo.c file but not the lis file. I saw in an earlier email that there was an lis file too. When I load servo.c there are undefined functions.
