INTERFACING: DISPLAY DEVICES

CHAPTER OBJECTIVES

In this chapter, the reader is introduced to different types of widely interfaced display devices with microcontroller-based systems. After completion of the chapter, the reader should be able to understand

  • How to interface light-emitting diodes (LEDs) and seven-segment displays.
  • How to develop software routines for controlling these devices.

19.1 | Introduction

Most of the microcontroller-based systems are equipped with some types of display devices for displaying output of the system or to generate some feedback signals. LEDs and seven-segment displays are most widely used in different systems as per the demand. Out of these two, LEDs are most inexpensive and easiest to interface and control. ...
