How many wires does the stepper motor have?

5-6 wires is unipolar (which most of the time it is..)

4 wires is bipolar...

search on the net for the specs...

you can even mail these guys about it...

if Ur motor has 5 wires it can be used only in Unipolar mode ..
4 wire only in bipolar mode

with 6 ,8 wires it can be used in both modes .....

With 5 wires you CAN use it in bipolar mode!

using only 4 wires and leaving the common one..

Go through AT89c51 data sheet, it will give enough information.

If u wanna know about registers and internal arch. go to www.8052.com.
There u can find good notes on 8051 which is similar to AT89c51.
