10. Appendix A – MODE OPERATION
10.1 WHICH MODE TO USE
Before setting up the development board, it is necessary to decide which operation
mode is appropriate for what you want to do. There are two choices:
Stand-alone Mode:
The IRADK31 Board is connected to a power supply and a
motor, but not to a computer. Motor operation is controlled through the two push
buttons, SW2 and SW3 (Start/Stop and direction) and the potentiometer, R28
(Speed). This is a simple demonstration of the board’s capability, and is useful
for verifying the board’s operation. It can also work as fast “sanity check” of
newly programmed control firmware.
PC Mode:
The IRADK31 Board is also connected to a host computer through a
serial interface. In this configuration, motor operation is controlled through a GUI
application on the computer; speed cannot be controlled from the potentiometer
on the board. The GUI allows more sophisticated motor operation, with
controllable speed, and real-time monitoring of motor operation.
Since both modes start with the same set-up procedure, we will start by describing
the set-up for the Stand-alone mode. Setting up the PC mode involves adding the
serial interface to the Stand-alone mode, and is covered later in this discussion.
10.2 SETTING UP THE IRADK31 BOARD: STAND-ALONE MODE
For evaluating the IRADK31 Board, the simplest configuration is to use the board by
itself, with no computer connection. This setup involves the following:
1. Connecting power to the board
2. Connecting the motor to the board (see Figure 2).
3. Verifying operation
For the sake of simplicity, we will assume that we are using the development board in
its default configuration for BLDC. This means that board jumpers are not installed
and the PIC18F2431 device has been programmed with BLDC control firmware. This
also assumes the use of a motor with built-in sensors for commutation, spaced at
60°. Some motors have Hall sensors spaced at 120°. Correct Hall Sensor spacing
can be found in the data sheet for the motor being used.
