(...) Thanks for your response. When we load the pcode_hb.s19file with the right CONFIG it seems to load properly. We then turn the HB off and back on and try to load the Interactive C. This does not work at the computer says "attempting to linkt to (...) (26 years ago, 30-Jan-99, to lugnet.robotics.handyboard)

Hi, I've just received a Sharp Digital Infra-Red Ranging System (GP2D02) and I'd like to connect it to the handyboard. The device clocks the data in on a digitial input but requires the clocking pulses to be no longer than 200 microseconds. This (...) (26 years ago, 30-Jan-99, to lugnet.robotics.handyboard)

(...) Well, just off the top of my head, when you say "get 16 vac out" how are you determining this, a volt meter set for "Volts AC" or some such? Not, say, an oscilloscope? You will note that almost all meters render "AC Voltage" as the RMS (Root (...) (26 years ago, 30-Jan-99, to lugnet.robotics.handyboard)

Fred- Thank you-it helps when you put the libraries that won't load into the right folder. I shall take up with Newton Labs why the HB won't talk to the HB and says out of date 2.81 code is out of date. Thank you again for all your help. Cappy (...)

I'm the one with the dead HB. When I look at R14 (next to the SPI header) it is black and is very hot. Do I have a dead resistor? Thank You Peter Eacmen BLS petereacmen@usa.net (26 years ago, 30-Jan-99, to lugnet.robotics.handyboard)

I have a transformer, when powered by 110 vac I get 16 vac out. I put it through a bridge rectifier and the problem is when I put a cap say 20v 1000uf across the + - of the rectifier, the voltage jumps to about 20 vdc. If I omit the cap and attach (...)
