Starting code composer studio

Before starting, it would be a good idea to create a folder where you will be saving your project files. Label the folder ELEC424_Tutorial .

To open Code Composer Studio in a Windows 2000 system, click on Start and select Programs --> Texas Instruments --> Code Composer Studio DSK Tools 2 (‘C2000) --> Code Composer Studio .

You should see the following screen:

You can double-click on the ‘ Untitled1 ’ window to make it larger.

To save your file, click on File --> Save . The following prompt will appear:

There are several Save as type… options. Choose the appropriate one for your code. It will give your file the proper file extension. It is also lets the linker know when you compile your code what kind of language the file is written in.

When you are done, click Save .

Creating a new project

After you have finished creating the files you need to run on the DSP, you will now want to create a project that will include all the files. Select Project --> New…

The following prompt will appear:

Fill in the project name in Project Name . Browse to the folder you created for the project in Location . Make sure you select Executable (.out) in Project Type , and select TMS320C28XX in Target . When you are done, click Finish .

When you are done, click Open .

You should now see the file after clicking on the ‘ + ’ in the left-hand window:

Compiling files and building projects

Once you have added all the files you want to be included in your project, you will now need to build your project. Select Project --> Rebuild All . You should see the following window at the bottom of the Code Composer Studio Environment:

If there are errors in your code, they will be listed with the corresponding line numbers. Correct them and rebuild your project.

Loading/reloading programs

After your code has been successfully compiled and built, you must now load your program onto the DSP. Select File --> Load Program… You will see the following prompt dialog:

When you rebuild your project, Code Composer Studio is set at default to create a new folder in your directory called Debug . This is where the executable file is created. Double-click on the Debug folder and you should see your *.out file:
