 | | Mini Board or Handy Board?
|
|
I am just getting into robotics and microcontrollers, and have run up against a brick wall. After gathering information on both the Handy Board and the Mini Board, I am unable to decide which to build first. Money is somewhat tight, so whatever (...)

Hi ! Again this is a question about the Polaroid Sonar Module. Some times ago I disasembled a partly dead Polaroid camera and now I have a neat little board with the sonar transducer conected to it.

Hans, Thanks for this. Actually, I am now using the CPP that comes with the GNU-C / AS11 set for the PCODE & *.ICB re-compilation. I call my real source *.IC and pre-process it into *.C, then let IC load that .C file. I am winning in a clumsy way I (...) (28 years ago, 6-Nov-96, to lugnet.robotics.handyboard)

David -- The MAX662 chip I used on the last beta rev was not the magic bullet I hoped. Not only is there possibly the rise time problem you mention, but when the thing turns off, it outputs 5v. The PIC needs a swing from 0v to 12v to enter program (...) (28 years ago, 5-Nov-96, to lugnet.robotics.handyboard)

David, Althuogh I don't have an expansion board either, I am in the middle of testing some code that I wrote to program pi16c84s. Everything seems to be working well, I just want to keep on testiong it before releasing it. I wrote it such that it (...) (28 years ago, 5-Nov-96, to lugnet.robotics.handyboard)

HI! I have got a little question about the expansion board: at the HB home page, I could read that the exp. board was not yet finished and that the programming of the PIC16C84 is impossible. In fact, I did not found any layout of the two layers of (...) (28 years ago, 5-Nov-96, to lugnet.robotics.handyboard)

Howdy, Ordinarily this would be a question better suited for comp.sci.electronics...g-or-other but since the Handy Board expansion interface uses a 4051, I figured someone here could give me the answer more quickly...

Hi Steve, The file hbtest.c allows you to test the various features of the Handy Board and make sure they are operational. To use hbtest.c, type "load hbtest.c" at the IC prompt. When the file is finished loading, you will see the IC prompt again. (...) (28 years ago, 5-Nov-96, to lugnet.robotics.handyboard)
