5.1 Connecting to the DRV8328xEVM GUI

Follow the instructions in Section 5 and ensure the LAUNCHXL-F280049C is connected to the PC. Turned on the supply to power the DRV8328AEVM and LAUNCHXL-F280049C.

Access the GUI Composer Gallery and search for "DRV8328" as shown in Figure 5-1. Click on the version of the GUI depending of the DRV8328 variant configured on the EVM. If using the DRV8328AEVM out of the box, select the DRV8328A_DRV8328C_EVM_GUI tile on the left.

Accept the readme that appears. The GUI will detect the LAUNCHXL-F280049C and automatically download the program into the MCU. Once complete, the “Hardware Connected” message appears at the bottom left hand corner as shown in Figure 5-2.

As shown in Figure 5-3, the following defaults should appear when the GUI is connected:

  • Direction – Enabled

  • PWM Frequency (Hz) – 20000

  • MCU Dead Time (ns) – 0

  • Acceleration Delay (ms/1% duty cycle) – 21
