I was looking on the Handy Board web page instructions on howw to wire sensors and motors to the HB. I thought that the two smaller ends went to ground and the longer transmitter side with a 330ohm resistor went to the 5v port and the longer recever (...)

|
|
Hello, I made a terrible mistake. By mistake I connected the pos. side of the powerheader (10 V) to the middle row of the digital ports (Vccc ; 5 V , (if I'm not mistaking)). With this action I probably blew up (a) component(s) on my handyboard. I (...) (28 years ago, 6-Dec-96, to lugnet.robotics.handyboard)

Have just got to the testing stage this lunch time and have a few problems. 1) When testing the motor ports the LEDs light up in the sequence M0 green - M0 red - M1 red - M1 green - M2 green - M2 red - M3 red - M3 green. This differs from the (...) (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.
