|
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 (...)

Hi everyone, I posted a message a day or two ago about a downloading problem I am having with my HB. I have gotten my hands on a copy of hbdl.exe and it too fails to download pcode_hb.s19. I believe that I am following all instructions properly. (...) (28 years ago, 6-Dec-96, to lugnet.robotics.handyboard)

|
|
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)

Hello, I'm trying to find information on how to implement infrared communication between my PC and my RugWarrior (a 68HC11 board). I want is to use the serial interface of the board (another port would be fine btw), which is normally connected via a (...) (28 years ago, 5-Dec-96, to lugnet.robotics.handyboard)

| | baud rates
|
|
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. Mike is correct in stating the place for info is the 6811 "pink book." See the HB (...) (28 years ago, 5-Dec-96, to lugnet.robotics.handyboard)

(...) Isn't that what the SPI is for? Set one up as master, and all others as slaves. Look in the 'pink' book. I don't know of any existing drivers, but Dr. Fred Martin at MIT has stated he will write some Real Soon Now, maybe January. Keep checking (...)
