Hello Everyone: I have just finished hooking up my vector2x compass and it seems to work fine thanks to Tom Brusehaver's good work and instructions.The only goof I made was to reverse the input and output lines. After about two hours of inspection (...) (27 years ago, 5-Jul-97, to lugnet.robotics.handyboard)

(...) Hi there Joe- (...) Yes, you're gonna like this- just about any "Optrex-compatible" LCD display can be used on the HandyBoard. There are two caveats however, most of these displays have a 14-pin header connection and not the 14-pin inline (...) (27 years ago, 5-Jul-97, to lugnet.robotics.handyboard)

Jeff, JDR Microdevices sells the General Insturments CTS256AL2 chip (GI8642CAA) for ** $4.95 **. This is (I think) a slightly newer version of the same chip that Radio Shack used to sell. I bought one of those with an order from JDR, but haven't had (...) (27 years ago, 5-Jul-97, to lugnet.robotics.handyboard)

Most robot builders work on mobile and walker robots. A few developers, however, have addressed another challenge: autonomous underwater vehicles.

(...) Wow, impressive board. However, it's a bit out of my price range - I was hoping for a solution just about as cheap as the Radio Shack one used to be.

Hej I'm had the same problem, until i found that I loaded some programs via lib-file, not suitably for HB. (lib_r22.c) It seems you are running some programs for the 6.270. Have You setup IC correct?

Hi Dale, For this to work a couple of things have to be true, first the Start_LCD, Stop_LCD, and putlcdchar() functions have to be located in the 256 bytes of on-board RAM (or in the 512byte EEPROM) The second thing is that your putchar_LCD doesn't (...)
