6 Firmware and GUI Application
The DRV8316REVM can implement sensored, sensorless, or Field-oriented control for commutating a three-
phase Brushless-DC motor. The supported firmware is a sensorless ield-oriented control algorithm adapted from
Texas Instruments’ MotorControl SDK Library of motor solutions. The algorithm includes motor identification and
parameters, sensorless sinusoidal commutation, torque and speed control, and field weakening to maximize the
performance of the motor. The firmware uses GUI Composer to run the algorithm and includes a tab to read/
write to the DRV8316 SPI registers.
The following steps describe how to identify useful motor parameters, spin the motor using a sensorless
sinusoidal profile, use the PI controller gain settings for torque and speed control, and communicate with the
DRV8316 SPI registers. For more information on advanced features of the C2000 InstaSPIN Universal GUI such
as 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 Hardware Setup and ensure the LAUNCHXL-F280049C is connected to
the PC and the power supply is turned on to the DRV8316REVM PCB.
2. Access the GUI Composer Gallery https://dev.ti.com/gallery/ and search for
"DRV8316REVM_InstaSPIN_Universal_GUI". Click on 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 .
