Overview

1 Overview
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.

GUI Application

3.1 Installation
Installation (For Desktop Version Only)
• Download the installable DRV8428_x.x.x_installer_win.zip file (The file is inside the
DRV8428xEVM_software.zip file. x.x.x is the GUI revision number).
• Extract the zip.
• Double click on the installer to install the GUI Application. During first time installation, the installer
prompts for installation of Cloud Agent. Please Install it. During the installation, customer company's
firewall may block "download from website" option for the GUI composer runtime installation, please
download GUI runtime v7.4.1 from this link: https://software-dl.ti.com/ccs/non-
esd/gui_composer/runtime/gcruntime-7.4.1-windows-installer.exe and save it to your local harddrive.
And then, use "Install from File" option to install the GUI composer runtime.
3.2 Getting Started with DRV8428P EVM GUI
The DRV8428P EVM GUI and DRV8428P EVM allows the user to configure various settings required for
BDC motor or stepper motor driving. The DRV8428P EVM GUI lets the user adjust the motor speed,
control the direction, control the step movement, configure various device settings, and monitor the device
status.
Perform the following steps to begin using the GUI:
• Connect the stepper motor to the EVM.
• Plug in the micro-USB cable to the PC.
• Enable the motor power supply. For additional details on hardware connections refer to the
DRV8428xEVM User's Guide
Click on DRV8428P EVM GUI shortcut either on the desktop or from the start menu to run the GUI
application.
3.3 Use the DRV8428P EVM GUI
