It details the hardware implementation of the CPG002 (DRV8800-01EVM) Customer Evaluation Module (EVM). 1 1. Introduction to EVM The CPG002 Customer EVM is a board containing all of the necessary components to evaluate the many features found on the DRV8800 and DRV8801 devices. The EVM makes the evaluation process easier by housing a microcontroller and an USB to Serial interface chip that allows for the user to control the different DRV8800 and DRV8801 signals by means of a graphical user interface (GUI). Figure 1. Block Diagram 1.1 Power Connectors The CPG002 Customer EVM offers terminal blocks for the application of VM power and for motor power outputs. VM power rail must be externally supplied. VDD for logic is internally supplied as it is derived from the USB connection. The user must apply VM according to datasheet recommended parameters. An USB Connection to a computer is needed for proper control of the device. 1.2 LEDs Three LEDs offer status information about power rails and microcontroller operating status. 1.3 Jumpers This EVM has no jumpers that need to be configured by the user.

Introduction to EVM 1.4 www.ti.com Motor Outputs There are two ways for connecting the motor load into the CPG002 Evaluation Module: A terminal block and a two pin header. Each connection style offers identical connectivity to the H-Bridge output terminals. 1.5 System Requirements · Supported OS – Windows 7 (32 Bit, 64 Bit). The window text size should be Smaller-100% (Default) · Recommended RAM memory - 4 GB or higher · Recommended CPU Operating Speed – 3.3 GHz or higher 2 GUI Software Installation The following section explains the location and the procedure for installing the software properly. 2.1 GUI Software Installation The following section explains the location of files and the procedure for installing the software correctly. NOTE: Ensure that no USB connections are made to the EVM until the installation is completed. The installer will also install LabVIEW RTE 2014 and FTDI Driver, along with the GUI. 6 SLVU335A – February 2010 – Revised July 2019 Submit Documentation Feedback Copyright © 2010–2019, Texas Instruments Incorporated GUI Software Installation www.ti.com 2.1.1 Installation Procedure The following procedure helps you install the DRV8800-01EVM GUI 1.

It is in charge of connecting to the EVM via an USB connection which in turn selects the proper logic state for the DRV8800-01EVM control signals. The Graphical User Interface (GUI) has been designed to allow for all of the DRV8800-01EVM device’s functionality to be tested without having to intervene with the hardware. Figure 20 shows the DRV8800-01 EVM High-Level Page. It contains menu items to configure and enable/disable the serial port and frames with GPIO control for the DRV8800-01EVM Control Signals as well as the ability to PWM the ENABLE and the PHASE inputs. Figure 20.

It contains frames with GPIO control for the DRV8800-01 control signals, motor control Frame, and PWM Frame. 3.1.1 High-Level Page 3.1.1.1 DRV8800-01 GPIO Control Signals Once the application is communicating with the interface board, the control signals can be actuated by checking or unchecking check boxes on the Signals frame. Green in the Pin control translates to the High level on the respective control signal and Red in the Pin control translates to the Low level on the respective control signal. Figure 21. Pin Information/Control Widget Clicking on the ENABLE and PHASE Boolean set the PWM duty cycle to 0x00 (when Low) or 0xFF (when High). Moving the slider bar configures the PWM duty cycle to a value in between. 26 SLVU335A – February 2010 – Revised July 2019 Submit Documentation Feedback Copyright © 2010–2019, Texas Instruments Incorporated DRV8800-01 EVM GUI Overview www.ti.com Figure 22.
