OPERATION DESCRIPTION

- Open the project "TOP_SUN.dpj" in the VisualDSP Integrated Development Environment (IDDE).
- Under the "Project" tab, select "Build Project" (program is then loaded automatically into DSP).
- Select "Run" from the "Debug" tab on the menu bar of VisualDSP.
- Color bar display on the TFT LCD.
