Introduction

In Chapter 19, our focus was on the programming aspects of 8051. Once that chapter is understood thoroughly, it becomes very easy to move on to the hardware features of 8051.

Any microcontroller needs to place most of its focus on interfacing with peripherals. External peripherals are to be controlled by programs tested and finally ‘burned’ ...
