#26779 - RE: PPI 8255 Control Problem |
Thanx Daz, I've checked it and it's my fault.
Another problem is with the programming. I've connect my PPI with PC Parallel Port. I connect the D0-D7 PPI with D0-D7 Parallel Port, and RD, WR, A0, A1 with pin 17, 16, 14, 1 Parallel Port respectively. How to program the PPI to make Port A Input, Port B&C as output ? |
