Keyboard Matrix Help (original) (raw)

v1.1 24 Jun, 2000

Attempts to explain how a keyboard matrix works, what "ghosting" and "masking" are, and how to prevent them.

1. Introduction

It took me a bit to figure this out, partly due to the fact of no really good explanation of it. So, I'm going to have a crack at it. Basically, I wanted to understand how keyboard matrices work. Specifically, I wanted to know why keyboard "ghosting" and "masking" happen, and how to prevent them.
