3.1 DRV8376EVM GUI Software

This section details the features of the EVM GUI Software. The GUI is written in GUI Composer and is available on the development software gallery at dev.ti.com/gallery.

The GUI connects and programs the C2000 MCU on the LAUNCHXL-F280049C board when launched, assuming the board is connected and powered. Once the hardware is connected, the FAULT status and voltage monitors match the EVM. If these do not match, then remove EVM power and recheck the setup. If the fault is triggered, then press the Clear Faults button on the GUI.

To spin the motor:

  1. Using a Google Chrome® browser, navigate to dev.ti.com/gallery and search for the DRV8376EVM GUI.
  2. After loading, make sure that the GUI connects to the board and shows Hardware Connected in the bottom status bar and that the MCU LED is turned on.
  3. Confirm that the GUI reports VM_Undervoltage Fault and Over-Current Fault.
  4. Turn on the power supply at and set the current limit on the power supply.
  5. Make sure AVDD, GVDD, and VM LEDs lights up green.
  6. Click the Clear Faults button on the GUI and confirm the fault light on GUI is clear (green) and check to see the DRV8376EVM NFAULT LED is off.
  7. Check the following items:
    1. GUI reads back the voltage being supplied.
    2. GUI shows no FAULTs.
    3. FAULT LEDs is now OFF.
  8. Toggle Output Enable to ON.
  9. Raise the Duty Cycle (%) to desired value and the motor starts spinning.
  10. If direction change is needed, then toggle the direction in the GUI, observe the motor slowing down to a stop, and then spinning in opposite direction.
  11. Disable the motor by switching the Output Enable to OFF.
