Dual Motor Control Plug-In Module (PIM) Information Sheet
The Dual Motor Control Plug-In Module (PIM) is designed to facilitate the development of Motor
Control applications using two motors and one Digital Signal Controller (DSC) or Microcontroller
(MCU). Two Microchip dsPICDEM™ motor control development boards can be used with this
PIM to control 3-phase or stepper motors. A flexible cable connects the two boards together and
routes all signals to the appropriate pins on the DSC or MCU. The configuration of the cable and
signal was carefully chosen to support a wide range of dual motor configuration application notes
written for the dsPICDEM MCLV, MCHV, and MCSM Development Boards.
Installing MPLAB
®
IDE and C Compilers
The MPLAB Integrated Development Environment (IDE) should be installed prior to running the
Dual Motor Control demonstration. While MPLAB provides the assembler tools for development,
most of the code examples are written in C language and require a C compiler to be installed.
Microchip’s MPLAB C compiler seamlessly integrates into MPLAB IDE. Both the MPLAB IDE and
MPLAB C compiler are free (see the note below) and are available for download at
www.microchip.com/MPLAB and www.microchip.com/compilers, respectively.
Code Examples and More Information
For code examples and more information, please visit the Dual Motor Control page at http://
www.microchip.com/motor. From the Development Tools menu, click Development and Evaluation
Boards and from the list select dsPICDEM Dual Motor Control PIM MA330027. Then, from the
Downloads section, select the code for the desired Application Note and Development Board.
Refer to Table 1 for the hardware settings required for each Development Board.
Running and Debugging Applications (MCLV) Development Board
After downloading the code example and installing the development tools, please use the following
procedure to build and run your software:
1. Connect one motor to each MCLV board as described in the “dsPICDEM™ MCLV
Development Board User’s Guide” (DS70331).
2. Place the two MCLV boards side by side, on a sturdy platform.
3. Carefully insert the Dual Motor Control PIM into U9 on each MCLV board. The board on which
the PIM labeled as Master is plugged into is referred to as the Master board. The other MCLV
board is referred to as the Slave board.
4. Connect a 24V power supply to J2 on both the Master and Slave boards.
5. Connect a programmer/debugger (i.e., MPLAB ICD 3 or REAL ICE™) using the J11 connector
on the Master board.
6. Extract the Dual Motor Control software previously downloaded and load the project file.
7. In MPLAB 8.XX IDE:
- Select Programmer > Tool
and then choose the appropriate tool.
- Build the project by selecting Project > Build All.
- Download your code to the DSC or MCU by selecting Programmer > Program.
8. In MPLAB X IDE:
- Select Run > Set Project Configuration > Customize.
- Select required tool under Hardware Tools. Click Apply > Ok to confirm the selection.
- Select Run > Run Project. This will download the code to the target chip and release
reset.
9. To start a motor, press the S2 button on the corresponding board. Press the S2 button again
to stop the motor.
10. Use the potentiometers on each board to change the speed of a motor.
11. For an enhanced demonstration, the application requires the Real-Time Data Monitor (RTDM).
Connect the development computer to J8 on the Master board with a mini-USB cable and
follow the instructions provided on the Dual Motor Control web page for additional instructions
on this demonstration.
Note: Standard Evaluation (Free) – All optimization levels are enabled for 60 days, but then
revert to optimization level 1 only.
Note: When using the Dual Motor Control PIM with the dsPICDEM MCHV Development
Board, connecting the GND test point to an oscilloscope must be done only through
a High-Voltage Differential Probe.
