6 Firmware and GUI Application

The DRV8329AEVM can implement sensored, sensorless, or Field-oriented control for commutating a 3-phase Brushless-DC motor. There are two GUIs to support DRV8329A (DRV8329A-EVM-GUI) and DRV8329B (DRV8329B-EVM-GUI) using sensored trapezoidal commutation with Hall sensor feedback. The GUIs allow 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 integrated CSA provide voltage and current feedback from the motor for over-current and motor voltage protection.

The following GUIs are available on the Gallery:
