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:
- 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.
- 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.
- 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.
- Connect the DC power supply to header J5.
Note: Observe
the correct polarity for the VBAT and GND connections on the DRV8317HEVM
connector J5.
- Connect a Micro-USB cable to the LaunchPad development kit and computer.
- 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.
