Will you be using an actual matrix (I hope not) or will you be multiplexing the inputs?
: I am curently in the proccess of designing a microcontroller based keyboard interface and I was wondering if anyone here has tried to do this themselves and can give me a few pointers/hints.
: Here are some of the features I'm thingking of
: 8x8 matrix
: RS232 port for PC programming
: keyboard through port so you can have your control panel and keyboard hooked together at the same time.
: 20Mhz clock speed (plenty fast enough!)
: 3 optional relays for turning lights on and off.
: Let me know what you think.
