PICDEM MC LV DEVELOPMENT BOARD SETUP
The following procedure describes how to set up the PICDEM MC LV Development
Board to run with a PIC18FXX31 device.
Board to run with a PIC18FXX31 device.
1.
Place the PICDEM MC LV Development Board on a sturdy platform.
2.
Make sure the PIC18F2331 or the PIC18F2431 is mounted in the “PIC” socket on U1.
3.
Connect the 24V power supply to J20.
LED D7 (red) should turn on. If it does not turn on, check the polarity of the power
supply connector. If it is correct and the LED D7 still does not turn on, disconnect
power to the board and contact Microchip’s local office or distributor.

power to the board and contact Microchip’s local office or distributor.
4.
Determine the algorithm you want to run the motor. The following two options are
available:
available:
• Speed control using Hall sensors
• Sensorless control
• Sensorless control
5.
Program the part with the desired algorithm. For generating a project and pro-

6.
Disconnect the power supply and complete jumper settings and motor connec-
tions as given in the following table. The wire colors mentioned in the brackets
are for the Hurst NT Dynamo motor, available from Microchip as an accessory,
part number AC300020.

WARNING
The PICDEM MC LV Development Board is intended to drive 3-phase BLDC motors.
Before connecting the motor, make sure that the power rating of the motor is equal
or less than the power rating of the board, as given in Appendix B. “Electrical Spec-
ifications”. Also, make sure that the jumper settings are correct for the firmware
programmed into the target PIC
