User`s guide

4 - Software

A number of software tools has been used and evaluated for this report, giving the user two

main alternatives when programming – either using Code Composer Studio (CCS) for

traditional coding, or modeling in Simulink. The specific programs and plugins used are:

Code Composer Studio v3.1

MATLAB R2007a

Simulink v6.6

Embedded IDE Link CC v3.0 (Link for Code Composer Studio)

Target Support Package TC2

The Code Composer Studio suite gives the user the choice of writing every row of code in

either c/c+ or assembler language, it is also in charge of the software-to-hardware handling.

Since most of the work in this report have been made through Simulink and automatic c-code

generation using the target- and link-package, CCS has more or less been reduced to a mere

compiler. It is nonetheless quite a powerful tool and a quick guide can be found in the

appendix section of this report.

The CCS v3.1 is shipped with a F2812-emulator – something which might prove itself useful

should the hardware be unavailable. All tested features in this report has however been

performed using the eZdsp F2812 from Spectrum Digital. It should also be noted that CCS is

compatible with a wide range of DSPs should one have second thoughts regarding the

suitability of the current DSP. Regarding the software compatibility CCS v3.1 is compatible

with Embedded Link CC v1.5-v3.0, in other words MATLAB R2006a-R2007a. For newer

releases of MATLAB, CCS v3.3 is required.

The screenshot below depicts CCS 3.1 in action. To the left the “Project window” with the

open project and all its associated files shown in a standard directory structure. The main part

of the screen is taken up by the “Program window”, allowing the user to view and edit opened

files. The “Output window” in the bottom left corner of the screen relays error messages and

warnings during and after compiling of projects. To the right of the “Output window” lays the

“Watch window”, an extremely useful tool when evaluating models due to the ability watch

variable values in realtime.
