  Re: Download from Notebook on Windows 2000
 
I don't know why HBDL doesn't work sometimes. Can you try dl.exe. It's part of the stock Interactive C distribution. There are command line switches to tell it to use COM2. You'll have to throw away the PIF file that comes along. Sometimes it works (...) (24 years ago, 11-Aug-00, to lugnet.robotics.handyboard)
 
  Download from Notebook on Windows 2000
 
Last year I had a desktop Compac running Windows 95. I used HBDL and never encountered any problems. We now have IBM thinkpads running Windows 2000 and I can't get the downloader to work. I went through the hardware sanity check on the HB pages and (...) (24 years ago, 11-Aug-00, to lugnet.robotics.handyboard)

  Comms Board to PC connection.
 
Could somebody confirm whether the comms board can be connected directly to the serial port of the PC (using 25-9 pin adapter is neccesary). I have a HC11 board from Mekatronix which has a comms board the can be plugged directly into the port, is (...) (24 years ago, 11-Aug-00, to lugnet.robotics.handyboard)

  Octal Latch Burn!
 
Hi, I think, that I burn the 74HC373 (octal latch), but before removing the chip I want to test it to be sure that the problem is there. But I don´t know how to test if the latch works fine. Any Ideas? Thanks Daniel Ramirez (24 years ago, 8-Aug-00, to lugnet.robotics.handyboard)

  IR Serial comms
 
I have recently come across an interesting IC being sold by RS Electronics in the UK. It is an IR transceiver IC which effectively gets connected to a normal serial UART and then just acts as though there was a physical cable in place. The IC does (...)

I can offer some input on this, as I have used both the Rug Warrior approach and the Handy Board approach that you describe.

  GP2D02 - problems?
 
Hi all, I used Gary Livicks routine in connection with the GP2D02 Sensor. When there is no obstacle in front of the sensor the LDC shows: "range is 77". Is that normal. Shouldn't the LCD display zero? If it is normal can you say me why? Thank you (...) (24 years ago, 19-Jul-00, to lugnet.robotics.handyboard)
 
  Re: Handboard exp.
 
Hi, I believe an earlier post indicated that, since the analog inputs on the expansion board are multiplexed to the analog input 0 on the HB, if you cut the trace on analog port 0, the expansion board analog ports will all be "pull-up (...) (24 years ago, 20-Jul-00, to lugnet.robotics.handyboard)
 
  GP2D12 on expansion board
 
Hi all, I am using three GP2D12 on the expansion board. When I connect them (after removing the analogue port 1 resistor and put the GP2D12 on port 24-26) I experience some weird problem.

  short-circuit?
 
Hi, This past few days, I notice my board uses up the battery very quickly (may be because I use servos). Then I notice that the voltage regulator at U13 heats up very quickly. I was wondering if I short-circuit somewhere. I didn't build the board, (...) (24 years ago, 19-Jul-00, to lugnet.robotics.handyboard)
