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.
