9 PERIPHERAL INTERFACING

This chapter describes interfacing characteristics of a microcomputer with typical peripheral devices such as a hexadecimal keyboard, display, DMA controller, printer, CRT (Cathode Ray tube) terminal, and coprocessor.

9.1 Keyboard Interface

9.1.1 Basics of Keyboard and Display Interface to a Microprocessor

A common method of entering programs into a microcomputer is via a keyboard. A popular way of displaying results by the microcomputer is by using seven segment displays. The main functions to be performed for interfacing a keyboard are

1. Sense a key actuation.
2. Debounce the key.
3. Decode the key.

Let us now elaborate on the keyboard interfacing concepts. A keyboard is arranged in rows and columns.

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
