Well I wanted to demo my new robot it was cool, but the day did not turn out to well. I think I switched the phone cables. When I tried to connect my interface board with the HB, it would not run IC. I then tried to download a new PCODE_HR.S19, but (...) (28 years ago, 28-Jan-97, to lugnet.robotics.handyboard)

1. Is it possible to expand the 32K RAM of the Handy Board? If so, how? 2. We will be using two shaft encoders (HEDS5500 from Hewlett-Packard) for our project. How can we interface the shaft encoders to the Handy Board? What inputs do we use? Does (...) (28 years ago, 28-Jan-97, to lugnet.robotics.handyboard)

I'm using the 1.2 volt NiCad's wired in series to give me 9.6 volts. If I want to get rid of one or two of the batteries, will the handyboard still run at 7.2 or 6.0 volts ? What is the minimum voltage that the handyboard will run on, 5V ? I dont (...) (28 years ago, 27-Jan-97, to lugnet.robotics.handyboard)

Anyway, you got to choose 3 books for like $5. Then you just had to buy one (...) (28 years ago, 27-Jan-97, to lugnet.robotics.handyboard)

|

(...) You'll need 3 input and 2 output lines. One input and two outputs are available at the SPI port, (right side of board, J6?). Find two more discrete inputs on the Handyboard and you're set. All the other inputs on the V2X can be hardwired high (...) (28 years ago, 27-Jan-97, to lugnet.robotics.handyboard)

Make sure your downloader is configured to download "pcode_hb.s19" and not any of the other variants (eg pcode_r22.s19). Avard, please send me an email and let me know if this solves your problem. -Fred In your message you said: (...) (28 years ago, 26-Jan-97, to lugnet.robotics.handyboard)

Ben -- the pin 27 R/W line of the RAM should be connected directly to the R/W line of the 6811. I don't remember the pin # off hand -- it's 7 i think -- but just check the schematic. check the continuity first on the board. if that's ok, then check (...)

My handyboard is experiencing some kind of a -POWER-GLITCH-. At least that's what is displayed just before the board shuts itself off. How did this happen, and what can I do about it? Thanks in advance. Avard Fairbanks (28 years ago, 26-Jan-97, to lugnet.robotics.handyboard)

(...) There are a number of ways to do this in C. If you get the code that comes with the Handyboard, they have msleep(500L); which sleeps for 500 milliseconds (L for LONG Integer) and then returns to the calling program. My code is at work, but I'm (...) (28 years ago, 26-Jan-97, to lugnet.robotics.handyboard)
