zip file provided, under the
USB Driver
folder. Run
“CDM
v2.10.00 WHQL Certfified.exe”
and follow the installation instructions.
Step 4: Run the GUI by starting the DRV8701EVM_GUIvX.X.exe file within the
DRV8701EVM_GUIvX.X folder from the “C:\ti\guicomposer\webapps\” directory
.

and
OUT2
for each motor wire.
Step 2:
Attach the main power supply to the terminal block header
(H10)
. This header is labeled with
VM
and
GND
. The DRV8701EVM supports 5.9- to 45-V supply voltage.
Step 3:
Plug the micro-USB cable into the board (supplies the microcontroller power and allows for GUI
communication) and then plug in the micro-USB cable to your computer.

DRV8701EVM GUI
The DRV8701EVM_GUI is provided with the DRV8701EVM to control a brushed DC motor and
manipulate various settings. The GUI provides functionality for adjusting the speed and direction of the
motor, adjusting the current regulation limit, observing the measured drive current, and monitoring the
device status.
The DRV8701EVM_GUI operates on the GUI Composer Runtime which must be
installed prior to use (see
).
Step 1:
Attach the brushed DC motor, plug in the micro-USB cable, and enable your motor power supply
(see
).
Step 2:
Run the
DRV8701EVM_GUI
(DRV8701EVM_GUIvX.X.exe). The executable is found at
C:\ti\guicomposer\webapps\DRV8701EVM_GUIvX.X\ DRV8701EVM_GUIvX.X.exe
. The top level
directory may be different, depending on your install settings.
