1. Introduction to mikroPascal PRO for ARM
mikroPascal PRO for ARM®
organizes
applications into projects consisting of a
single project file (file with the
.mppar
extension) and one or more source files (files
with the .c extension). The mikroPascal PRO
for ARM® compiler allows you to manage
several projects at a time. Source files can be
compiled only if they are part of the project.
A project file contains:
•
Project name and optional description;
•
Target device in use;
•
Device clock;
•
List of the 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.

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
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 the mikroPascal PRO for ARM® compiler from the
Product
DVD
or download it from the MikroElektronika website:
http://www.mikroe.com/eng/products/view/753/mikroPascal-pro-for-arm/
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 ARM® compiler. The mikroPascal
PRO for ARM® IDE (Integrated Development Environment) will appear
on the screen. Now you are ready to start creating a new project.

3. Creating a New Project
The process of creating a new project is very
simple. Select the
New Project
option from
the
Project menu
as shown below. The
New
Project Wizard
window appears. It can also
be opened by clicking the
New Project icon
from the
Project toolbar.
The
New Project Wizard
(Figure
3-1)
will
guide you through the process of creating
a new project. The introductory window of
this application contains a list of actions to
be performed when creating a new project.

Step 1 - Project Settings
First thing we have to do is to specify the
general project information. This is done
by selecting the target microcontroller, it’s
operating clock frequency, and of course
- naming our project. This is an important
step, because compiler will adjust the
internal settings based on this information.
Default configuration is already suggested
to us at the begining. We will not change the
microcontroller, and we will leave the default
LM3S9B95
as the choice for this project.
