Hi Ed -- it *could* be that the desktop you're using isn't set up right to download to the HB's. do you have a known good HB you can use to test the download? alternately, there are some serial line debug instructions at (...) does not boot (...)

I am currently using my parallel port for the same application. I am not sure how specific your question was, but the output voltage is 5Vdc. However, remember that this is a logic level which means it will not give not give you more than ~20mA ( I (...) (25 years ago, 15-Sep-99, to lugnet.robotics.handyboard)

In C you can use the functions outport and inport, and the paralell port has TTL levels (5 V.).

Its Easy to do in pascal as well as C++ using the PORT[address] command. Ive used It before to control external devices. A normal parralell pot has 8 outputs D0 - 7 and a few lines that you can use as inputs (not sure which ones though?) The port (...) (25 years ago, 13-Sep-99, to lugnet.robotics.handyboard)

Yeah! You're right! I've seen it done in Basic so I would assume C++ has a function. But, I don't remeber wether they are at 12V or 5V. (?) (...) (25 years ago, 13-Sep-99, to lugnet.robotics.handyboard)

Isn't your parallel port itself what you want? I always understood that it could be reached (coded) quite easily? That should give you 7 channels! ----- Original Message ----- From: Peter <eacmen@att.net> To: Handy Board Mailing List (...) (25 years ago, 13-Sep-99, to lugnet.robotics.handyboard)
