Reference Design Graphical User Interface (GUI)

Rev 1.0

INTRODUCTION

The Reference Design Kit Graphical User Interface (RDK-GUI) provides an easy way to configure motor

control system parameters. These parameters are related to the user’s motor type and model. The param-

eters which can be configured include the following:

■type of the motor driven;

– 3PH PMDC/AC or BLDC/AC (trapezoidal driven), or

– 3PH AC induction motor, or

– 3PH PMAC or BLAC (sinusoidal driven)

■number of the poles pairs of the motor; and

■control method.

Other, more specific parameters include types of control (i.e., Ramp Up Acceleration Speed for the “3PH

BLDC/AC trapezoidal” or Variable Frequency Control for the “3PH AC Induction” motor).

These settings reside in the .h headerfile used with the designkitsoftware library (see Compiling the Stan-

dalone RDK Libraries, page 16). The .h file is automatically generated by the GUI and/or can be modified

manually by the user. To generate the firmware for the ST7MC microcontroller, the .h file and the software

library must be compiled using the

Cosmic

Metrowerks

compiler in the ST Visual Develop v3.2.0 or Soft-

ec STDV7 v3.10 environments. The firmware is then downloaded into the microcontroller memory (see

GENERATING THE BINARY CODE FILE (.S19) USING STVD7, page 14).

Some features of the GUI are disabled and cannot be used with the RDK at this time, but they are left to

illustrate the complete features of the microcontroller. If you want to use these features, please refer to the

ST7MC Starter Kit at http://www.mcu.st.com.
