|
|
Hello all, I know it's a pretty stupid question, but anyone knows how am i supposed to clear(in Interactive C) the LCD screen of the HandyBoard ? I've tried printf("\n"); printf(" "); but it doesn't work. Thank you very much. Marcelo Manjon (26 years ago, 4-Sep-98, to lugnet.robotics.handyboard)

Phillip: In the process I was referring to, you do not use the Handy board, driver or anything to determine the step sequence. You only use the motor and a battery (after you finish with the Ohm meter). The idea is to learn what the motor is (...) (26 years ago, 4-Sep-98, to lugnet.robotics.handyboard)

Hi, I was wondering how the expansion board is doing? Is out of testing? Any major glitches? Ilya (26 years ago, 4-Sep-98, to lugnet.robotics.handyboard)

hi all, we had a filesystem upgrade last night and both of the Handy Board web servers (el.www.etc and lcs.www.etc) are presently down. Hope to have at least one of them running later today. Fred (26 years ago, 2-Sep-98, to lugnet.robotics.handyboard)

[Randy Sargent] spake unto the ether: (...) Sigh. I can't forsee our Autonomous Robotics course buying 15 copies of IC 3.x or greater until it supports case/switch.

| | Resend: problems with main()
|
|
I posted earlier in the week about having a problem with the SRAM. I have determined that there is not a problem with the SRAM on the handyboard. The problem is that "main()" is not executing on reset like it is supposed to. The program that I am (...) (26 years ago, 27-Aug-98, to lugnet.robotics.handyboard)

Hi, There is another way to get the Polaroid sonar unit. And that is to find an old Polaroid camera. That's the hardest part but allot of people bought them and are not using them any more. When you open it up there will be the Sonar board complete (...) (26 years ago, 27-Aug-98, to lugnet.robotics.handyboard)

Phillip First step is to put a piece of tape on the shaft so that you can clearly see the shaft turn. Next determine what kind of motor you have (you have probably already done this). Get an ohm meter and determine which wires are connected to (...) (26 years ago, 27-Aug-98, to lugnet.robotics.handyboard)
