Adapt9S12DP256M Development Board - Closed-loop Stepper Motor Control

Hi,

How to use this development board in order to develop the stepper
motor control system? What are the module/block I should use in this
system?

Basically, my system is like this:
1. Firstly, there will be a Graphical User Interface (GUI) for the
user to input their desired position, speed and direction. This GUI
will communicate with MC9S12DP256B through RS232. Any reference for
this part?

2. MCU will drive the stepper motor according to the GUI input via
a motor driver board (3540M from Applied Motion Products). The driver
needs three input namely STEP, DIRECTION and ENABLE. Motor will step
on rising edge of STEP input.

3. Next, incremental encoder will feedback its position to MCU.
There will be also a home sensor for homing routine once power is on.

4. When the motor is in desired position, user will purposely turn
the motor to cause position error. Then user will press a 'correct
button' in GUI to drive the motor back to its actual position. There
will be a button to enable and disable the driver board on the GUI.

Any help is highly appreciated.

I suggest you do a subject search at http://tech.groups.yahoo.com/group/68HC12/ as well as looking through the files are.
Every student before you asked just about the same question at yearly intervals.

Happy engineering.
