6 Firmware and GUI Application
The DRV8311HEVM can implement sensored, sensorless, or Field-oriented control for commutating a 3-phase
Brushless-DC motor. The supported firmware is a sensorless Field-oriented control algorithm adapted from
Texas Instruments’
MotorControl SDK Library of motor solutions. The firmware includes motor identification and
a sensorless FOC algorithm to spin the motor. The firmware uses the DRV8311HEVM InstaSPIN Universal GUI
to run the algorithm and includes tabs to read from and write to the DRV8311 SPI registers (DRV8311S only).
The steps below will describe how to identify useful motor parameters, spin the motor, and work with the
DRV8311S SPI registers. For more information on more advanced features of the C2000 InstaSPIN Universal
GUI such as torque and speed control, MTPA, or Field-weakening, consult the MotorControl SDK InstaSPIN Lab
Guide (in the
MotorControl Software Development Kit tool page ) and InstaSPIN-FOC and InstaSPIN-MOTION
User’s Guide .
6.1 C2000 InstaSPIN Universal GUI
1. Follow the instructions in Section 5 and ensure the LAUNCHXL-F280049C is connected to the PC and the
power supply is turned on to the DRV8311HEVM PCB.
2. Search for the GUI Composer Galllery through https://dev.ti.com/gallery/search/drv8311xevm . You will to
login with a myTI account in order to access the GUI.
3. Accept the readme as shown in Figure 6-1 and check the bottom left hand corner of the screen for
“Hardware Connected”. Once connected, the GUI will flash the algorithm to the MCU as shown in Figure 6-2 .
