PICDEM™ MC LV Development Board

5. Disconnect the power supply and ensure that the jumper settings and motor

connection match Table 6-1 and Table 6-2 respectively.

TABLE 6-1: JUMPER SETTINGS

TABLE 6-2: MOTOR CONNECTIONS

6. Keep the potentiometer “REF” on the 50% or center position. Turn the pot

marked “R60” to the full clockwise position.

7. Connect the 24V power supply to the board. The red LED D7 will turn on.

8. To start the motor, press S2.

9. To increase the speed of the motor, turn the potentiometer marked “REF”

clockwise.

10. If the motor stops, press S2 once to reset the process and repeat steps 9-11.

11. The debug information will be relayed via the serial port. Connect Hyperterminal

at 19200 baud to view the speed of the motor, or any Fault which occurs during

the execution of the code.

WARNING

Note 1: When programming the dsPIC device on the PICDEM MC LV Develop-

ment Board, the two DIP switches must be in the PRGM position. This

will ensure the programming pins are connected to the programmer. If the

user has generated independent code, the user must select

EMUC2/EMUD2 pins for emulation in the MPLAB Configuration menu.

These alternate pins will then be programmed and will be used for the

debugging or run phase.

2: After programming the dsPIC device, the user can disconnect the pro-

grammer from the ICD 2 plug J6 and run the device in Stand-Alone mode.

Alternatively, if the ICD 2 is being used in the Emulator mode, then the

DIP switches have to be switched to the DEBUG position. Then, the

EMUC2/EMUD2 pins will be connected to the ICD 2, and assuming the

configuration was done as described above, the user will be able to run

the firmware using the ICD 2 as an emulator.
