I am building a somewhat similar circuit (a high-current h-bridge for the handy board), although I only need to read the data lines. However, the same approach will work for writing to the bus. My circuit lives on a board which plugs in between the (...) (27 years ago, 14-Jan-98, to lugnet.robotics.handyboard)

Hello, I've bought a handy board, and try to build a card to enserve two motors. On that card I have a IC chip (HP hctl 1100) that needs to be link to a 8 bits Adress/data bus in both reading and writing modes. My problem is where to pick such a bus (...)

Joshua - There should be no problems using the Gleason Research libraries (or any of the libraries that are on the web site). There are no differences between version 2.851 and 2.860 from the point of view of the libraries. There is a pre-compiled (...) (27 years ago, 13-Jan-98, to lugnet.robotics.handyboard)

Hi (...) You could use spezial interface chips to solve your problem. Hewlett Packard has some chips (HCTL2016, HCTL2020) which are easy to use and offer a lot of features. I have used the HCTL2020 with the handyboard. If you want to interface the (...) (27 years ago, 12-Jan-98, to lugnet.robotics.handyboard)
