Experiment # 6 - Introduction To Code Composer Studio

Report Due on 10/22/08

Read the lab manual thoroughly and follow each steps with caution.  Here's a quick overview...

  1. Connect the board to the PC parallel port and power it up.
  2. Choose [Setup Code Composer] from the [Start] menu and check if your system configuration is "C6711 DSK". Select [Save & Quit] and hit [Yes] to open Code Composer on exit.
  3. Now let CCS know that you have connected your board, by selecting [Debug]->[Connect].
  4. Select [GEL]->[Check DSK]->[Quick Test] and look for the message "Target is OK".
  5. Create a new project named lab6 and save it in My Documents or in your USB drive. CCS may not detect the network drive K: for some reason.
  6. Create a new configuration file from [File]->[New]->[DSP BIOS Config]. Choose your board "C6711.cdb" and hit ok.
  7. In the DSP BIOS configuration window, open [System]->[Global Settings] and re-check the board type to make sure it is "dsk6711".
  8. Save the configuration file to your project directory, and add it to your project by right-clicking on the project name and choosing [Add files to project]. To add the file, you may also choose [File]->[Add files to project].
  9. Similarly add the source files and header files necessary for the project. Download and unzip the files necessary for lab6 from here.
  10. Build the project by choosing [Debug]->[Build Project]. (Shortcut [F7]).
  11. If the file is not loaded automatically to the board, choose [File]->[Load program] and browse for the executable file "lab6.out" in the "debug" folder. (Shortcut [Ctrl]+L).
  12. Run the downloaded program on the DSP board by choosing [Debug]->[Run] (Shortcut [F5]).

Experiment # 7 - Graphing Capabilities of CCS Time/Frequency Graphs

Report Due on 10/29/08

Read the lab manual thoroughly and follow each steps with caution. Here's a quick overview...

  1. First step here is to generate coefficients for an IIR filter to represent a sine wave.
  2. Write an M-File in MATLAB to generate 2nd order IIR coefficients for representing a 3kHz sine wave.
  3. Assume that 64 samples are taken during each period of the sinusoid.
  4. Download and unzip the files for lab7.
  5. Edit the source files based on your results from step # 2.
  6. Follow the steps to create a project, build the project and load it to the DSP board.
  7. Run the program and halt it.
  8. Now select [View]->[Graph]->[Time/Frequency].
  9. Make the following changes to the properties window.
       
    Graph Title Lab # 7
    Start Address buffer
    Acq. Buff Size 64
    Disp Data Size 64
    DSP Data Type 16-bit signed
    Sampling Freq 8000
  10. Hit [OK]and you should see a sine wave.
