4.4.1 DRV8317H Compatibility
The DRV8317HEVM default is the DRV8317H (Hardware variant), which can be used to spin a 3-phase
Brushless-DC motor with selectable modes configured with hardware settings as shown in Table 4-3.
When using the DRV8317H, resistors R8, R9, R10, R11, and R12 must be left unpopulated. This allows the user
to select settings using the MODE, SLEW, and GAIN pins by using jumpers on J10, J9, and J8. An outline of the
various hardware selectable settings can be found below.
Note
In order to change the hardware settings for the GAIN, MODE, or SLEW using the appropriate
jumpers, the device must first be powered off or put into sleep mode in order for the new hardware
settings to take affect.

4.4.2 DRV8317S Compatibility
The DRV8317HEVM is compatible with the DRV8317S (SPI variant) to spin a 3-phase Brushless-DC motor. The
DRV8317S replaces the hardware settings (MODE, SLEW, and GAIN) with 4 SPI signals: SDI, SDO, SCLK, and
nSCS.
When using the DRV8317S, the DRV8317S variant IC needs to be soldered onto U1 in place of the DRV8317H,
and resistors R9, R10, R11, and R12 must be populated with 0-ohm resistors. Additionally, the jumpers must be
removed from J8, J9, and J10. This properly connects the SPI signals to the correct pins on the device.
4.4.3 MCU Power Options
The DRV8317HEVM has several options for powering the LAUNCHXL-F280049C or an external MCU. Table 4-4
provides a description of the various MCU power options.

4.4.4 Interfacing DRV8317HEVM and LAUNCHXL-F280049C LaunchPad
The DRV8317HEVM has 40 pins with different functions. These pins are interfaced with the
LAUNCHXLF280049C LaunchPad development kit and are mapped appropriately to receive the functionalities
of the DRV8317H device. These 40 pins are grouped into 4 ports in respect to the LAUNCHXL-F280049C (J1 to

5 Hardware Setup
The hardware required to run the motor control is the LAUNCHXL-F280049C LaunchPad development kit, the
DRV8317HEVM, a Micro-USB cable, and a power supply with a DC output from 4.5-V to 20-V. Follow these
steps to set up the evaluation module:
1. Check that all resistors or jumpers are set up accordingly according to the device variant used. The
DRV8317HEVM by default is populated with and configured for the DRV8317H (hardware variant). If using
the DRV8317S, please populate the resistors mentioned in row I of Table 4-2 to configure the board for the
proper device variant.
2. Mate the DRV8317HEVM board to the top half of the LAUNCHXL-F280049C LaunchPad development kit
(mates to J1/J3 and J2/J4 of LaunchPad, as in Figure 4-3).
Note
Observe the correct orientation when placing DRV8317HEVM to the LAUNCHXL-F280049C. The
motor and power connectors will face to the LaunchPad’s Micro-USB connector.
3. Connect the three phases from the brushless-DC motor to the 3-pin connector J6 on DRV8317HEVM.
Phases OUTA, OUTB, and OUTC are labeled in white silkscreen on the PCB top layer.
Note
If using a sensored algorithm on the LaunchPad development kit, connect Hall sensors to the
5-pin connector J7.
4. Connect the DC power supply to header J5.
Note
Observe the correct polarity for the VBAT and GND connections on the DRV8317HEVM connector
J5.
5. Connect a Micro-USB cable to the LaunchPad development kit and computer.
6. Turn on the power supply and power up the PCB.
If using the DRV8317HEVM with an external microcontroller, make the connections needed on the male headers
on the top of the board or female connectors on the bottom side of the board.

6 Firmware and GUI Application
The DRV8317HEVM 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 DRV8317HEVM InstaSPIN Universal GUI
to run the algorithm and includes tabs to read from and write to the DRV8317 SPI registers (DRV8317S only).
The steps below will describe how to identify useful motor parameters, spin the motor, and work with the
DRV8317S 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 DRV8317HEVM PCB.
2. Search for the GUI Composer Galllery through https://dev.ti.com/gallery/search/DRV8317xevm. You will
need to login with a myTI account in order to access the GUI.
3. Accept the readme if the readme message pops up.
4. Select the "InstaSPOIN-FOC" tab at the top right hand corner to go to the main page of the GUI. Check the
bottom left corner of the GUI to see if the GUI flashes the algorithm to the MCU as shown in Figure 6-1.
Once the device has completed flashing the algorithm, it should show “Hardware Connected” in the bottom
left corner.
Figure 6-1. C2000 InstaSPIN Universal GUI Downloading Program
6.2 Motor Identification
1. Check the “Enable System” box to enable the InstaSPIN algorithm and run preset calibrations. Wait for the
“OffsetCalc” button to uncheck automatically to finish calibrating board offsets.
2. Check the “Run” box to begin the motor identification algorithm as shown in Figure 6-2. The motor will
begin to spin and stop as it goes through many states to calculate and identify useful motor parameters for
sensorless Field-oriented control. This should take no more than a few minutes.
3. Once the motor identification process is complete, the “Motor Identified” indicator will light up, the “Run” box
will be automatically unchecked, and the values Rs, Rs Online, Ls-d, Ls-q, Flux, and Rr will update for that
motor as shown in Figure 6-3. These values will be automatically used for Field-oriented control.

Figure 6-3. Motor identification complete using the DRV8317HEVM InstaSPIN GUI
6.3 Sensorless-FOC Commutation
1. To spin the motor with sensorless FOC, check the “Run” box again. The motor will spin with sinusoidal
current at the speedRef (Hz) value in the GUI, which is automatically set to 20.0 Hz. Use the speedRef (Hz)
input to change the current speed of the motor as shown in Figure 6-4. The GUI automatically calculates
the current reference speed using the variable speed (Hz) and compares it to the trajectory speed variable
speedTraj (Hz) to calculate the Speed Error (Hz) as a percentage.

To implement more advanced modulation techniques such as torque control, speed control, and algorithms such
as MTPA, Field-weakening, and PowerWarp (EPL) using the DRV8317HEVM InstaSPIN Universal GUI, please
consult the MotorControl SDK InstaSPIN Lab Guide found in MotorControl SDK.
This document contains detailed lab overviews of how to implement each advanced modulation technique when
using sensorless FOC to spin the BLDC motor in Code Composer Studio. In order to use the project with the
GUI, the user must build and compile the project in CCS, and import the .out binary file for that project into the
GUI properties through GUI Composer. More information can be found in the README when the GUI is first
opened.
6.5 SPI Communication (DRV8317S only)
The DRV8317HEVM InstaSPIN_Universal_GUI includes two SPI register tabs for the DRV8317S device variant:
Status Registers and Control Registers.
1. Click on the “DRV8317S Control Registers” tab to access the DRV8317S Control Registers as shown in
Figure 6-5.
2. Choose the desired settings by selecting from the drop-down menus for each setting. Clicking a setting
description selects the bits required for that control register setting. Consult the DRV8317 datasheet (in the
DRV8317 Registers section) for detailed definitions of settings.
3. Click on “Write” to write to all control registers in the device with the configured settings.
4. To read all status and control registers in the device, click on “Read”. The statuses and settings will
auto-populate in the DRV8317S Status Registers and Control Registers.
5. Alternatively, to write data to a specific address, input the address and data in decimal into the address and
data inputs above the “Manual Write” box. Click on the “Manual Write” box to write the data to that address.
To read data from a specific address, input the address in decimal into the address above the “Manual Read”
box. Click on the “Manual Write” box to read the data from that address.
