SX Microcontroller based Keyboard IO

PC Keyboard interface / tester

by George F. Hotz

Hello, I'm George Hotz. Here is my keyboard-lcd interface. (Yes, it works
for me)

Thank you for hosting these contests.

Reads PC keyboards and displays Scan code or decoded ASCII to an LCD.

The connections are as follows:

It uses the SX Key/Blitz to program it, and runs using the internal 4mhz oscillator

Source with scan code display

Source with decoded ASCII display

Source which prints the keyboard keys to the LCD

Entered in the Embedded Starter contest June 2002
