I've had an idea for a PC hardware interface rolling around in my head for a while, but after doing some inital investigation on the web, I have not found anything that has helped me get started yet.
It basically goes like this...
I have a series of 256 momentary switches. I need to wire these switches somehow, and interface them with a standard off-the-shelf PC (Parallel interface???), and produce an 8-bit number from 0 to 255 (depending on which switch is pressed). This number should be something that I could pick up using VB)
So, my questions are...
- Is this even possible?
- Is there a ready made device that an do this?
- Are there plans for a device that can do something similar to this?
Thanks! ferrell
