Hello!
I have little knowledge about parallel port programming on Linux. I wan't to know if its possible to like 'listen' if the current is incoming into data pin? What I need is forexample I have two wires, one from Data pin 1 and other from ground, if I put them together some function will return for example 1 else 0! Does anybody know something about this function!? I think its called inb(); Thanx!
what you are going to need to do is "poll" the pins. This can be done in multiple ways, but if you want the simplest, just go with a while loop that reads data from those pins, then calls/does something when you recieve certain results.
there used to be something here, but not anymore
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
