6.1 Connecting to the DRV8329AEVM-GUI

Follow the instructions in Section 5 and ensure the LAUNCHXL-F280049C is connected to the PC. Turned on the supply to power the DRV8329AEVM and LAUNCHXL-F280049C.

Access the Gallery and search for "DRV8329" as shown in Figure 6-1. Click on the GUI for the variant.
