Let’s make a simple “Hello world” example

for the selected microcontroller. First thing

embedded programmers usually write is a simple

LED blinking program. So, let’s do that in a few

simple lines of Pascal code.

LED blinking is just turning ON and OFF LEDs that

are connected to desired PORT pins. In order to see

the example in action, it is necessary to connect

the target microcontroller according to schematics

shown on Figure 2-1. In the project we are about

to write, we will use only PORT0, so you should

connect the LEDs to PORT0 only.

Priortocreatinganewproject,itisnecessarytodothefollowing:

Step 1: Install the compiler

Install the mikroPascal PRO for 8051 compiler from the Product

DVDordownloaditfromtheMikroElektronikawebsite:

http://www.mikroe.com/mikropascal/8051/

Step 2: Start up the compiler

Double click on the compiler icon in the Start menu, or on your desktop

to Start up the mikroPascal PRO for 8051 compiler. The mikroPascal

PROfor8051IDE(IntegratedDevelopmentEnvironment)willappear

on the screen. Now you are ready to start creating a new project.
