Instructions to the

students:

• Student has to construct microcontroller mini-project individually as per

given

circuit diagram by the faculty. It is compulsory as a part of term

List of

components is given at the end of this lab

anua

• Mounting of RS-232 connector and MAX-232 chip is compulsory for all

students

because it will help you to program your chip using Philips

ash

Magic Utility (You

have to download HEX files in your chip to test

you

)

• Simulate assembly language programs on UMPS assembler and

• Simulate C programs using KEIL compiler and

• You may use free integrated development environment (IDE) for 8051

wit

Ubuntu

Linux. Linux operating system is open source so it is convenient to

use

it. Many free

simulators are available to work with Linux

env
