AVR-Chat

Hello,

    Iam a student of electronics & communication engineering. Iam 
working on a project titled Infrared Tracking system using AVR 
ATMega32 Ucontroller on STK 500 starter kit.

      The objective of our project is to track a mobile object 
continuously and to display its position on a television. A beacon, 
placed on the object to be tracked, continuously emits infrared 
signals in all directions. The signals coming from the beacon are 
detected by 2 IR receivers mounted on 2 stepper motors, which rotate 
independently and are in separate locations. The direction each 
receiver is pointing towards, allows the CPU to determine the 
position of the beacon via triangulation. The position of the tracked 
object is then displayed on the TV, where the center point is the 
middle point of the 2 receivers.

     Iam stuck at coding the stepper motor drive. I need some help on 
implementing a bipolar stepper motor and writing its code to program 
the microcontroller. The stepper motor has to generate a sweeping 
pattern to find the location of the object...Iam in need of help from 
some experienced avr programmers. Also suggest me some links for 
bipolar stepper motor codes...

Thanks a lot in advance...
Cherry.
