Hi I don't have any objection to putting the modified files up for general download - I only added Julian's code to the 3.1 source... I also modified the "boot" message so that it is obvious that you are running the new PWM code. I've changed the IC (...) (27 years ago, 21-Jan-98, to lugnet.robotics.handyboard)

Scott, Thanks for incorporating Julian's changes into the 3.1 pcode. In fact, if we can have Julian's permission and yours as well, Scott, we'd be very interested to be able to redistribute the improved pcode with IC 3.1. Scott and Julian, would (...)

I haven't seen the schematic you're refering to but I believe you can use the +5V bus already on a standard HB. Just connect your PWR/GND to one of those headers "below" one of the A/D inputs. I did this before and it worked. Apparrently, the 1A +5V (...) (27 years ago, 19-Jan-98, to lugnet.robotics.handyboard)
