4.1.2.3.1.3.1 Start CCS and Open a Project

To quickly execute this build, follow the following steps:

  1. Make sure that all jumpers on the board are correctly installed or removed as listed in the Hardware section.
  2. Hardware Set-up: Insert the F28004x controlCARD in the 100-pin DIMM connector. Connect a 12 V DC bench power supply between TP10 and TP11 with correct polarity. Connect an isolated 400V programmable DC power source to the 400 V input connector and 12 V electronic load to the 12 V connector (make sure that this load does not exceed the board ratings). Connect a USB cable between the PC and controlCARD. Do not turn ON any of the power supplies at this time.
  3. Open Code Composer Studio. Maximize Code Composer Studio to fill your screen. Close the welcome screen if it opens up.
  4. locate the solution package downloaded and import the project in CCS
  5. In the project window on the left, click the plus sign (+) to the left of Project. Your project window will look like the following:
