Getting started with code composer studio v3.3 for tms320 f2812

  1. 1. Getting Started with CodeComposer Studio v3.3 forTMS320F2812
  2. 2. OBJECTIVETo understand the basic features andfunctions to create and debug a project in CCSv3.3To get familar with CCS v3.3More in-depth explanations of CodeComposer Studio’s various features .Ex: Breakpoints,watch window, single stepping,memory etc..,Finally, you will able to work with CCS v3.3
  3. 3. IntroductionCode Composer Studio is the IntegratedDesign Environment for the Texas InstrumentsDSP/DSC/MC.DSP – TMS320C6745DSC – TMS320F2812MC – MSP430F5529Code Composer Studio is the environment forproject development for all tools needed tobuild an application for the Specific Target.
  4. 4. Contents at a GlanceSetting up a TargetCreate a projectBulid a ProjectRunning a projectBreakpointsSource steppingWatch window
  5. 5. Launching The CCS v3.3 Click this icon shown on yourdesktop. To launch Code Composer StudioIDE for the first time, configure CodeComposer Studio for a specific target.
  6. 6. Setting Up The Target Double-click theSetup CCStudio iconon desktop.
  7. 7. Target InformationIn Family, Select C28xx.In platform, Select XDS 100 USB Emulator.In Endianness, Select little.Then Select F2812 XDS100 USB Emulatorfactory board.Select Add.Select Save and Quit.
  8. 8. Creating a New Project Launch Code Composer Studio. From the CCStudio Project menu, choose New.
  9. 9. Project Name : Type the project name.Location field : Type or browse to the folder where youwant to save projectBy default, Project Type is set as Executable (.out) andTarget is set as the current configuration of CCS.
  10. 10. From the CCStudio File menu, choose New – SourceFile.
  11. 11. Type the program in untitled window then , File –Save. The Save As dialog box will appear. Choose ourproject path and type practice.c – Click save.
  12. 12. Add files to the project by choosing Add Files toProject from the Project menu. You can also right-clickthe project in the Project View window on the left andthen select Add Files to Project.
  13. 13. Add practice.c, DSP281x_GlobalVariableDefs.c, andF2812_EzDSP_RAM_lnk.cmd (this is a linker commandfile that maps sections to memory) from the folder youcreated.
  14. 14. Project - Build Options.In compiler tab –preprocessor -Include Search Path(-i) :C:tidcsc28DSP281xv120DSP281x_headersinclude - preprocessor path
  15. 15. In linker tab,1. Select Basic –a. stack size(-stack):0x4002. Select Libraries –a. Search path(-i):C:CCStudio_v3.3C2000cgtoolslibb. Incl Libraries(-l):rts2800_ml.lib3. Click Ok.
  16. 16. Now that you have created a functional program, youcan build it. Use the Project - Rebuild AllThe Rebuild AllCommand ismainly used torebuild theproject when theproject optionsor any files in theproject havechanged.
  17. 17. An output window will show the build process andstatus. When the build is finished, the output windowwill display Build complete 0 errors, 0 warnings.
  18. 18. Connecting the TargetNote: Before doing this step be sure that powercable and usb cable has plugged.After the program has been built successfully,connect the target by going to Debug - Connect.The Target is now connected with code composerstudio, at once the disassembly window will open.Status Displayed in status bar at the bottom of theCCStudio window.
  19. 19. Load the ProjectAfter the Target has been connected successfully,load the program by going to File - Load Program. Bydefault, CCS IDE will create a subdirectory calledDebug within your project directory and store the.out file in it. Select practice.out and click Open toload the program.File – Load Program – Debug – open – Practice.out –open.Note: Remember to reload the program by choosingFile - Reload Program if you rebuild the project aftermaking changes.
  20. 20. Go MainTo begin execution of the Main function,Select, Debug – Go Main. The execution halts at the Main function and youwill notice the program counter (yellow arrow) in theleft margin beside the function. This is called theselection margin.
  21. 21. BreakPointsTo set a breakpoint, place the cursor on the desiredline and press F9 or by selecting the ToggleBreakpoint toolbar button.When a breakpoint has been set, a red icon willappear in the selection margin. To remove thebreakpoint, simply press F9 or the Toggle Breakpointtoolbar button again. You can also open the Breakpoints Manager ( Debug– Breakpoints ) to view all the breakpoints, set newones, or change the breakpoint action.
  22. 22. In practice.c, set a breakpoint at the line: k=i*i; Asexecution was halted at the main function(in go mainstep),Select Debug – Run , you can press F5 , select theRun toolbar button to run the program. Once execution reaches the breakpoint, it halts, asdisplayed in the status bar at the bottom of theCCStudio window.After reached the breakpoint, it halts later you giverun or Single stepping. Now we will see the sourcestepping to run further.
  23. 23. Source SteppingSource stepping is only possible when programexecution has been halted. Since you halted at thebreakpoint, you can now execute the program lineby line using source stepping.
  24. 24. Step into the while(1) Loop function by selecting theSource-Single Step button on the side toolbar. Stepthrough a few times to observe the executions. TheStep Over and Step Out functions are also availablebelow the Single Step button.Assembly stepping is also available. Whereas sourcestepping steps through the lines of code, assemblystepping steps through the assembly instructions.Now we will see something about Watch Window,later we follow the execution of above exampleprogram, then we understand about breakpoints ,source stepping and watch window together.
  25. 25. Watch WindowIn the debugging process, you should view the valueof the variables to ensure that the function executesproperly. Variables can be viewed in the watchwindow when the CPU has been halted.The watch window can be opened by selecting View– Watch Window. The Watch Locals tab shows all therelevant variables in the current execution. Once theprogram reached breakpoint then , it halts.Select , View – Watch Window., watch window boxappear in ccs itself
  26. 26. As you continue to Step Into the while loop, thevalues of the variables change through eachexecution.Example: As per our previous discussion, programexecution reached breakpoint then it halts, weopened the watch window to viewing the varibles.Now the value of k is zero, then follow the belowsteps to understand breakpoint, source stepping andwatch window. Degug – run (or) click this icon Nowsee the watch window
  27. 27. Again Degug – run (or) click this iconNow see the watch window
  28. 28. In addition, you can view the values of specificvariables by hovering the mouse pointer over thevariable or by placing the variables in the Watch1 tab.
  29. 29. Output Window The Output window islocated at the bottomof the screen by default.It can also be accessedby View – OutputWindow. By default, theprintf function displaysthe same Outputwindow, showinginformation such as thecontents of Stdout andthe build log.
  30. 30. HelpCCS provides many help tools through the Helpmenu. Select Help Contents to search by contents.Select Help Tutorial to access tutorials to guide youthrough the CCStudio development process.Select Help Web Resources to obtain the mostcurrent help topics and other guidance. Usermanuals are PDF files that provide information onspecific features or processes.You can access updates and a number of optionalplug-ins through Help Update Advisor.
