This page is about electronic projects I have done for the parallel port of my PC. Normally you would connect
the various circuits to a microcontroller but I just haven't gotten started with them. To test, program and
basically see things work I started to connect things to my parallel port. It's not without problems, there are
fewer pins than on a average microcontroller but on the other hand you have all the displaying capabilities
and computing power of your pc.
Projects I did that are currently missing a page :
- 8 LEDs and a button to trig interrupts (Super trivial).
- 2 buttons and a 74LS74 D-FF for testing interrups (Trivial, overkill).
- A Real Time Clock DS1287.
Brief notes on the details of the parallelport : here
Projects
Display - A standard 2x24 chars display with HD44780 controller (Status : Success).
CallerID - A Caller ID device (Status : Success, QnD test software working).
