Programming Stepper motor using 16f877a

can anyone give me the program for programming stepper motor using 16f877a using microcode studio.

Probably not, but if you search, there are plenty of examples here already. What are you looking to do with stepper motors?

Here's one that I wrote to control a stepper motor. Haven't looked at it a while. The stepper motor drives a synchro transmitter that drives an airspeed indicator. It was written for a 16F636, but that should not require many changes to move to a 16F877...not sure.

the stepper motor must be a bipolar one.
i need the coding for a stepper motor with three or two terminals

it is for designing a robotic arm and these stepper motors will be place in finger joints and hence for a finger i will be having three stepper motors.
In total there will be 14 stepper motors (since for thumb i require just 2 stepper motors).

i was very much confused with interfacing them.
so can anyone help me with it

To drive a bipolar stepper you will need a dual hbridges, and this makes life a little more difficult. There are several chips ready to use, the choice depend from the motor power. The logic for moving is the same for unipolar and bipolar.

Read the totorial @ http://www.divms.uiowa.edu/~jones/step/ to know more.
