1. Introduction of Code Composer StudioCode Composer Studio Integrated Design Environment for

the C2000 Family of Texas Instruments Digital Signal Processors.

Simply, Code Composer Studio is the environment for project

development for all tools needed to build an application for the

C2000-Family.

The objective of this module is to understand the basic

functions of the Code Composer Studio 3.3, how to create anddebug a project in CCS 3.3 for TMS320F2812/F28335 kit. This

following section will introduces some of the basic features and

functions in Code Composer Studio so you can create and build

simple projects. Experienced users can proceed to the following

sections for more in-depth explanations of Code Composer

Studios various features.

Finally, you will able to work the TYRO-TMS320F2812/TYRO

TMS320F28335 kit with CCS 3.3

5. Click the Yes button to start the Code Composer Studio IDE with

your configuration. You can now start a project.

4. Creating a New Project

To create a working project, follow these steps:

1. If you installed Code Composer Studio in C:\CCStudio_v3.3,create a folder called practice in the

C:\CCStudio_v3.3\myprojects folder or use your any otherlocation .


7/26



Note:

There is no default configuration, you must set a configuration

before starting Code Composer Studio. See Chapter 2.1 for

more about Code Composer Studio configurations.

2. Launch Code Composer Studio. See Chapter 23. From the CCStudio Project menu, choose New.

4. In the Project Name field, type the project name (practice).5. In the Location field, type or browse to the folder you created

in step 1.

6. By default, Project Type is set as Executable (.out) and Target isset as the current configuration of Code Composer Studio.


8/26



7.Click Finish. Code Composer Studio creates a project file calledpractice.pjt. This file stores your project settings and references

the various files used by your project.

8.From the CCStudio File menu, choose New Source File.


9/26



9.Type the program in untitled window then , File Save. TheSave As dialog box will appear. Choose our project path and

type practice.c Click save.


10/26



10. Add files to the project by choosing Add Files to Project fromthe Project menu. You can also right-click the project in the

Project View window on the left and then select Add Files to

Project.

11. Add practice.c, DSP281x_GlobalVariableDefs.c, andF2812_EzDSP_RAM_lnk.cmd (this is a linker command file that

maps sections to memory) from the folder you created.


11/26



Note: You may need to

choose All Files from the

Files of type dropdown

box to view all the types

of files.

12.

From the CCStudio Project menu, Build Options.13. In compiler tab, Select preprocessorInclude Search Path(-i): (paste the path where our include files are

available) C:\tidcs\c28\DSP281x\v120\DSP281x_headers\include -

preprocessor path


12/26



14.

In linker tab,Select Basic

stack size(-stack) = 0x400

Select Libraries

Search path(-i):C:\CCStudio_v3.3\C2000\cgtools\lib

Incl Libraries(-l):rts2800_ml.lib

Then Click Ok.

5. Build a ProjectNow that you have created a functional program, you can

build it. Use the Project - Rebuild All function the first time you

build the project.


14/26


15/26



After the program has been built successfully, connect the

target by going to Debug - Connect.

The Target is now connected with code composer studio, at

once the disassembly window will open. Status Displayed in status

bar at the bottom of the CCStudio window.

Note: Before doing this step be sure that power cable and

usb cable has plugged.


16/26



7. Load the ProjectAfter the Target has been connected successfully, load the

program by going to File - Load Program. By default, Code

Composer Studio IDE will create a subdirectory called Debug

within your project directory and store the .out file in it. Select

practice.out and click Open to load the program.

File Load Program Debug open Practice.out open.


17/26



Note: Remember to reload the program by choosing File - Reload

Program if you rebuild the project after making changes.

8. Go MainTo begin execution of the Main function,

Select, Debug Go Main.

The execution halts at the Main function and you will notice

the program counter (yellow arrow) in the left margin beside the

function. This is called the selection margin.


18/26



9. BreakPoints

To set a breakpoint, place the cursor on the desired line andpress F9. In addition, you can set the breakpoint by selecting the

Toggle Breakpoint toolbar button.

When a breakpoint has been set, a red icon will appear in the

selection margin. To remove the breakpoint, simply press F9 or

the Toggle Breakpoint toolbar button again.


19/26



You can also open the Breakpoints Manager ( Debug

Breakpoints ) to view all the breakpoints, set new ones, or change

the breakpoint action.

In practice.c, set a breakpoint at the line: k=i*i; As execution was

halted at the main function(in go main step),

Select Debug Run , you can press F5 , select the Run toolbarbutton to run the program.


20/26



Once execution reaches the breakpoint, it halts, as displayed in

the status bar at the bottom of the CCStudio window.

After reached the breakpoint, it halts later you give run or

Single stepping. Now we will see the source stepping to run

further.

10. Source SteppingSource stepping is only possible when program execution has

been halted. Since you halted at the breakpoint, you can nowexecute the program line by line using source stepping.

Step into the while(1) Loop function by selecting the Source-

Single Step button on the side toolbar. Step through a few times

to observe the executions. The Step Over and Step Out functions

are also available below the Single Step button.


21/26



Assembly stepping is also available. Whereas source stepping

steps through the lines of code, assembly stepping steps through

the assembly instructions.

Now we will see something about Watch Window, later we

follow the execution of above example program, then we

understand about breakpoints , source stepping and watch

window together.

11.Watch WindowIn the debugging process, you should view the value of the

variables to ensure that the function executes properly. Variables

can be viewed in the watch window when the CPU has been

halted.

The watch window can be opened by selecting View Watch

Window. The Watch Locals tab shows all the relevant variables in

the current execution. Once the program reached breakpoint

then , it halts.

Select , View Watch Window., watch window box appear in

ccs itself


22/26



As you continue to Step Into the while loop, the values of the

variables change through each execution.

Example: As per our previous discussion, program execution

reached breakpoint then it halts, we opened the watch window to

viewing the varibles. Now the value of k is zero, then follow the

below steps to understand breakpoint, source stepping and watch

window.

1.Degug run (or) click this icon Nowsee the watch window


23/26



2. Again Degug run (or) click this icon

Now see the watch window


24/26



In addition, you can view the values of specific variables by

hovering the mouse pointer over the variable or by placing the

variables in the Watch1 tab.

12.Output WindowThe Output window is located at the bottom of the screen by

default. It can also be accessed by View Output Window. By

default, the printf function displays the same Output window,

showing information such as the contents of Stdout and the build

log. See Output window image in chapter 5

13.HelpCode Composer Studio provides many help tools through the

Help menu. Select Help Contents to search by contents. Select

Help Tutorial to access tutorials to guide you through the Code

Composer Studio development process.

Select Help Web Resources to obtain the most current help

topics and other guidance. User manuals are PDF files that

provide information on specific features or processes. You can
