mikroC PRO for ARM
®
organizes applications
into projects consisting of a single project file
(file with the
.mcpar
extension) and one or
more source files (files with the .c extension).
The mikroC PRO for ARM
®
compiler allows you to
manage several projects at a time. Source files
can be compiled only if they are part of a project.

A project file contains:
• Project name and optional description;
• Target device in use;
• Device clock;
• List of project source files;
• Binary files (*.emcl); and
• Other files.
In this reference guide, we will create a new project,
write code, compile it and test the results. The
purpose of this project is to make microcontroller
PORTA LEDs blink, which will be easy to test.

VCC-3.3
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 C 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
PORTA,
so you should connect the LEDs
to PORTA only.

Prior to creating a new project, it is necessary to do the following:
Step 1: Install the compiler
Install mikroC PRO for ARM
®
from the
Product DVD
or download it
from the MikroElektronika website:
http://www.mikroe.com/mikroc/arm/
Step 2: Start up the compiler
Double click on the compiler icon in the Start menu, or on your
desktop to Start up mikroC PRO for ARM
®
. The mikroC PRO for ARM
®
IDE (Integrated Development Environment) will appear on the
screen. Now you are ready to start creating a new project.
