Programming Parallel Port
807580Dec 10 2009 — edited Dec 10 2009Hi all!
I'm new with java and I would appreciate some help!
What I'm trying to do is to control an external device, like 8 LEDs, to turn them on and off using parallel port, data lines( pins 1....9 );
Maybe someone of you guys already had made this and you could give me some tips or some direction to follow.
What I already know is that I have to set one of the parallel bits to +5V and some of them to 0V in order to simulate that the device(printer) is ok.
I know that I have to use additional library "comm.jar" but in this package there are no useful methods in order to control data lines.
Maybe I am missing something!
Thanks
