Has anybody use the 62256LP-10, instead the 62256LP-120. Because I use and it doen´t work, I´m starting to think, that it may be a HandyBoard problem, not a memory one. Daniel ---...--- " `BETTER´ IS THE ENEMY OF `GOOD ENOUGH´" ---...--- (25 years ago, 17-Jun-99, to lugnet.robotics.handyboard)

Did you initialize them? You have to issue the initialization command to turn them on. init_expbd_servos(ON) (where ON=1) init_expbd_servos(OFF) (where OFF=0) turns them off Then give the servo a positioning command. servo(x) = y (where x is servo (...)
