5 Firmware and GUI Application
The DRV8328AEVM can implement sensored, sensorless, or Field-oriented control for commutating a 3-phase
Brushless-DC motor. The GUI for the DRV8328AEVM supports sensored trapezoidal commutation using Hall
sensor feedback and allows for basic trapezoidal motor control functions such as acceleration, duty cycle
control, PWM switching frequency, MCU dead time insertion, braking, and direction changes. The bus and phase
voltage feedback circuits as well as the external CSA provide voltage and current feedback from the motor for
over-current and motor voltage protection.
There are two versions of the GUI. The DRV8328A_DRV8328C_EVM_GUI only supports the “A” and "C"
versions of the DRV8328, and the DRV8328B_DRV8328D_EVM_GUI only supports the "B" and "D" versions of
the DRV8328.

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 .
