hello people.
i've been trying to send an 8 byte string to my parallel port under freebsd. the purpose is it to control a relay board. the board simply responds to the output byte coming from the port. eg. 00000001 will set pin 1 high and flick the relay open. todate i've attempted this with merely open() on /dev/ppi0 and numpy for the byte array, but i just can't seem to get it working. i know the parallel port works and i know the relay board works (tested it with it's own windows ultility) so it's just my crappy programming keeping me from success. -- http://mail.python.org/mailman/listinfo/python-list
