Figure 10. DRV8428 EVM GUI (Menu Bar – Help Option)

3.3.5.1

File Menu

The user can load the firmware (.out) file onto the onboard MSP430 by clicking file menu and selecting an
appropriate motor driver device to match the EVM variant. For the firmware load to work, MSP430 FET
needs to be plugged into the J2 connector on the EVM board.

3.3.5.2

Options Menu

This menu provides the option to configure the serial port communication settings.

3.3.5.3

Tools Menu

The "log pane" option in this menu is to open a log pane at the bottom of the GUI which shows the GUI
