Hello!
I would like to try some simple room automation projects, and use the parallel port to allow me to control different aspects of my room.
I think I could pull it off simply enough; wait for port.x to be high, and when it is (after receiving signal from parallel port), do a set of actions.
I am aware that I will need a level converter, and this would be easy enough if I was using a serial port with the max232 chip. However, I have no idea which chip I would use in order to adequately communicate with the PIC using the parallel port.
The reason I am stuck with the parallel port is because my computer (that is in my room) does not have a RS-232 port. And just for some background information: I will use a PIC16F628A to play around with this at the beginning, but may move up to a PIC16F871 if I am in need of more pins.
Thank you very much for your help,
-Omar
