Abstract
A keyboard scan code snooper device comprises a microcontroller, a display, and an oscillator. The scan code snooper may be attached to the data and clock lines of a keyboard serial interface connecting a keyboard with a computer in a pass through configuration. The firmware in the microcontroller processes the snooped data transmission from the keyboard to the computer and vice versa, and generates signals appropriate to drive the display.
