Mike, My HB does similar things and to fix it I just turn the board of and then on again without leaving ic(shareware v) and it generally sychronises. Joe Martin Email:joema@mpx.com.au ---...--- (...) (27 years ago, 15-Jul-97, to lugnet.robotics.handyboard)

| | 68hc12?
|
|
I'm currently assemblying a handyboard and came across some literature for Motorola's 68HC12 microcontroller. The one thing that attracted me to it is its built in memory-mapping capabilities. Do people generally find the handboard's 32K limiting? (...) (27 years ago, 14-Jul-97, to lugnet.robotics.handyboard)

I think i am still having trouble with the memory on my home brewed rug warrior board. I am using a 68hc11a1fn chip. I completely rewired it and i am positive it is wired correctly, however i still cant get the pcode to run. It will downlod (...) (27 years ago, 13-Jul-97, to lugnet.robotics.handyboard)

I've tried the enable_cheesy_encoders and it doesn't seem to work for me either. What I get is 0 for the portX_shaft_count all the time. Is this what you're getting? I've looked at the code but I couldn't see why it wouldn't work. Were you or anyone (...) (27 years ago, 11-Jul-97, to lugnet.robotics.handyboard)

I need help on understanding the motor controller circuit. Looking at the source in the lib_hb librariy it looks like different pulse trains are sent out to increase the average output voltage by poking increasing values of 256 into the rught (...)

James, Thanks for following up. The reason for this behavior should be fairly evident -- there are traces very close to the mounting screw holes. Your metal washers must have shorted them together, affecting wires to the memory. I do mention to use (...) (27 years ago, 11-Jul-97, to lugnet.robotics.handyboard)

| | RE: Corrupted or Invalid Pcode?
|
|
I've discovered the problem. When I mounted the Handyboard, I used metal standoffs. When the board is mounted, it doesn't work. When it isn't, it does. The solution then I guess is to use nylon washers to isolate the Handyboard from the standoffs. (...) (27 years ago, 11-Jul-97, to lugnet.robotics.handyboard)
