scale current level appropriately for your specific motor. Refer to the datasheet for the exact formula for
full scale current.
9. The Set All button takes the settings in the GUI and writes them to the DRV8711. Click this button to

Figure 13. BOOST-DRV8711 GUI REGISTERS Tab
1. The BOOST-DRV8711 GUI provides access to all of the register settings of the DRV8711. Use this
page to fine tune the motor driver settings. The register name as well as its hexadecimal address is
shown. Refer to the DRV8711 datasheet (
) for a more detailed description of each setting.
2. The Reset Faults button resets any faults that have occurred while driving your stepper motor. If a fault
occurs while spinning your motor (FAULT LED lights ups), select this button to clear the fault. Selecting
the button only clears the fault if the fault condition has been removed. Please refer to the DRV8711
datasheet for a detailed description of possible fault conditions.
3. The Manual SPI Read/Write section allows you to manually read or write hexadecimal values to the
DRV8711.
4. The Write All button updates the DRV8711 with the values set in the GUI. The Read All button updates
the GUI with the values from the DRV8711.
