The DRV8428P EVM is a platform to support prototyping and evaluation for the DRV8428P, a medium-voltage dual H-bridge driver for brushed DC and stepper driving applications.
The EVM uses an MSP430™ microcontroller and a USB interface chip to manage communication from the GUI software application installed on a PC computer with Windows®. The GUI sends serial commands to the MSP430 to control the device signals, monitor faults, read and write SPI registers, and drive a stepper motor by issuing the step commands at the desired rate. This document describes the software and tools used to evaluate DRV8428P device for stepper motor driving on the DRV8428P EVM.
