Hi Everyone
I have pretty much done my research but I am not confident that what I am setting out to do is correct, I was hoping to post here and double check my logic.
I want to wire wrap circuits that will have either no firmware or will have a microcontroller set up as a SPI slave.
I can control my parallel port with inb, outb and ioperm or with ioctr. I am still investigating ppdev.
If I toggle the data lines up and down and read the signal on my oscilloscope the square wave...
