I have 6 16F628's each controlling similar machine operations - need a program for a master PIC to communicate with a PC running VisBasic.net via a parallel port interface (8 I/O). The master PIC will then need to send pulses to each machine-control PIC every 3 seconds or so, as defined by the PC. I was thinking of using the first 3 I/O of the parallel port for PIC addressing, the next 3 for data, etc.
I'm fairly new at this stuff. I was able to create the code and build the small PIC units, but this is out of my league. Can anyone help me?
