4.7.2 Software Setup

The following software packages are required to build and run the software:

Setup the LED example software by following these steps in CCS:

  1. In the CCS menu, click 'Project -> Import CCS Projects...'.
  2. Enter the path to the F28003x driverlib CLB example projects in the ‘Select search-directory’.
    1. Path: <C2000WARE_INSTALL>\driverlib\f28003x\examples\clb
  3. Click ‘Refresh’.
  4. Select the ‘clb_ex32_led_driver’ project.

  5. Check ‘Copy projects into workspace’.
  6. Click 'Finish' to complete importing the project into the workspace.

    Optional: Click 'Project -> Build Configurations -> Set Active -> CPU1_LAUNCHXL_FLASH' to build the code for flash execution.

  7. In the CCS menu, click 'Project -> Build Project' to build the example project.
  8. Right-click the TMS320F280039C_LaunchPad.ccxml file in the project and select "Set as Active Target Configuration".
  9. Click 'Run -> Debug' to load the executable to the F280039C target device.
  10. Lastly, click 'Run -> Resume' in the CCS Debug perspective to run the code.
