Follow this link for data about the GP2D12. At the bottom, there is another link for Handy Board interfacing information. You have to cut a trace because the analog inputs on the Handy Board are connected to pullup resistors. The GP2D12 won't work (...) (26 years ago, 20-May-00, to lugnet.robotics.handyboard)

Greetings, I've looked, but don't seem to be able to find any relevant info. How does one hook up one of these beasts to the handyboard? I remember reading something somewhere that a track needs to be cut to do this - something I would like to avoid (...) (26 years ago, 20-May-00, to lugnet.robotics.handyboard)

(...) These two (...) ports. (...) I built the Expansion board in order to control servos. I cannot use the additional analog inputs because I have destroyed analog port 0 and 1. Is it possible to multiplex other analog ports? What software changes (...) (26 years ago, 19-May-00, to lugnet.robotics.handyboard)

Has anyone used the Hamamatsu C3704 Drive Circuit and the R2868 Flame Detector with the handyboard? The detector works great on my scope but I can't get the Handyboard to read it on a digital in port. Do you have to add a capacitor to lengthen the (...)

(...) That's what I was thinking too. But there is another consideration: the 6809 is a different class of processor than the 68HC11. The HC11 is a microcontroller while the 6809 is more of a general puropose microcomputer CPU. Although either could (...) (26 years ago, 18-May-00, to lugnet.robotics.handyboard)
