Hello! Boy do I feel silly! I'm captain of a robotics team here at Washington University and I ran into a problem tonight while soldering up my board. We've been building the board from the kit and all has been well until now. My assistant and I (...) (28 years ago, 6-Dec-96, to lugnet.robotics.handyboard)

Hi Dave, can you try the DLM.EXE (not hbdl) program off the software resources web page? you will have to use the "-256" flag because it defaults to -512 for the e1 version of the 6811 which is probably not what you have. also, if you have windows (...)

Not a real systematic one -- that seemed to be enough to let motors blast away, but stop real damage from happening if the nicad pack got shorted out. remember, shorting nicads is a real hazard - 50 to 100 amps -- could almost start a car. -fred (...)

I looked up the part in DigiKey Catalog. Is there a reason for choosing a fuse rated at 2.5A with a trip of 5.0A? (28 years ago, 6-Dec-96, to lugnet.robotics.handyboard)

Hi all, I have a question concerning baud rates and the SCI port. I looked in one of the pink books and found the maximum baud rate it shows is 131.072k baud. I need it to be 250k baud. I also noticed that the baud rate is dependant on the crystal (...) (28 years ago, 5-Dec-96, to lugnet.robotics.handyboard)

(...) Just to be clear: the code I have promised is 1200 asynchronous serial output from the HB (from a pin other than its built-in RS-232 out :-), *not* SPI code.
