Due Aug. 31, 2001
You make work in groups on this. Turn in enough so that I can tell that you
did the work (a copy of your program, a wiring diagram for (2), a list of
inverted and non-inverted pins for (3).)
Note: You may do the following using linux if you prefer.
- Compile and run the program hello.c in Getting Started with the DJGPP Compiler using
- Compile and run a program to write the data register and read the status register of the parallel port
on your PC. Use a jumper to connect some pins to verify that the program
works (e.g., connect 2-10, 3-11, 4-12, 5-13 and 6-15).
Verify that the status changes as you write different numbers to the data
- Verify that some of the status inputs are inverted and others are not.
