I ran into the same problem. I was unable to set it with any of the utilities for the handyboard. I ended up using my mini-board and its download software to correctly set the register. I don't know why it worked. Andy hobbytec@cas.auracom.com (...) (26 years ago, 2-Apr-98, to lugnet.robotics.handyboard)

(...) This won't work, as the servo's require a one-shot, not a variable duty cycle type of pwm (like what comes from the motor drivers on the HB). ie. the width of any given pulse is not consistent, just the overall duty cycle.

Thanks Clancy, but I tryed this already and without success. The hbdl loader says "Invalid CONFIG reg (0xFF) Try again" and when I check the eeprom area with PCBUG11, it is already there. I think, the E2 has a special protection for the CONFIG reg. (...) (26 years ago, 2-Apr-98, to lugnet.robotics.handyboard)

No I can't believe that the config register is unchangeable, because I own a single 68hc811e2 that has a correct config, but 12 others that dont, also these are used in the miniboard pre handyboard? with a config set at 0d, if i remember my old (...)

Hi All, I have come across a RugWarrior board that I think has a bad uC chip. I don't want to pull the chip form my HB to test it just in case I'm wrong.
