Matrix Keypad Introduction

Introduction Most of the applications of embedded systems require keypads to take the user inputs, especially in the case where an application requires more keys. With simple architecture and easy interfacing procedure, matrix keypads are replacing normal push buttons by offering more inputs to the user with the lesser I/O pins. As a Human Machine … Read more
