Stepper Motor Demo Application

Spinning Your Stepper Motor
After a successful launch of the
BOOST-DRV8711_GUIvX.X.exe
,
pops up. It may take a small
period of time before the GUI connects and the GUI Widgets populate (red X's appear on the widgets
while the GUI is connecting). If the GUI does not load after a few minutes (the X’s disappear), a
connection issue may have occurred and TI recommends restarting the application.

pin high to bring the DRV8711 out of sleep mode. The DRV8711 now begins
regulating current.
4. Adjust the
Stepper Motion Profile
parameters to the desired values. The units are
