4. Connect the 24V power supply to J6.

5. Press S1 to run the motor.

6. Vary the motor’s speed with the potentiometer.

7. Press S1 to switch to full-step wave mode, full-step, half-step and various

microstepping modes. Pushing S1 after the 256

microstep step setting stops

the motor. Press S1 again to repeat the cycle.

Operating the dsPICDEM MCSM Development Board using the on-board POT and

switch button cannot offer the flexibility required in most applications and it is only

intended as a quick start demonstration. To have more control over the motor using a

real-time communication tool, please refer to the next section.

2.2 PROGRAMMING AND DEBUGGING APPLICATION CODE

The following procedure describes how to program the dsPICDEM MCSM

Development Board in Debug mode:

1. Place the dsPICDEM MCSM Development Board on a sturdy insulated platform.

2. Make sure that the dsPIC33FJ32MC204 device or an appropriate PIM is

mounted in the respective socket.

3. Connect the stepper motor (42HS03) to J8. Connect motor phases in a bipolar

series connection as described in Table 2-1.

4. Connect the 24V power supply to J6.

5. Connect PICkit™ 3 In-Circuit Debugger/Programmer, MPLAB

ICD 3 or MPLAB

REAL ICE™ In-Circuit Emulator to the computer and to the board at J1 or J2.

6. Connect the USB cable to J4 and to the computer.

7. Download the code for the dsPIC33FJ32MC204 from the Microchip web site .

8. Build the project and download the program into the processor.

9. Click the Run icon when in Debug mode.
