Dear Steve, Nobody wants to hear this said, and I hate to be the one to do it, but you can start by reading the data available on the Handy Board web site (quick duck to avoid thrown volt meter). Fred has done what you want to do (memory-mapped (...) (25 years ago, 18-Jun-99, to lugnet.robotics.handyboard)

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)

Daniel: Yes I am running two handy boards with 62256LP-10 's that I have stripped from a scrap controller board of some sort. They work just fine.

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 (...)
