Hi...
I am using a microcontroller kit which has AT89C51ED2 on it. Actually i want to program that in order to rotate two stepper motor both clockwise and anticlockwise. ( the stepper motor which i want to use has 1.8 degree per step of motion).
So i am bit confused with that. So if any one can help me with that and can provide me .asm and .hex files so that i can use it. That will be very helpful.

Thanks in advance.

regards,
rits

hi rits,
check this secton:

if u are connecting two stepper moteors all u have to do is duplicate the same logic for the four different outputs of the second motor.

hi..thanks..... i checked that but can you suggest me how to convert .asm file to .hex file.
and also has anyone tested the program given in the tutorial.
I even need the connection diagram of L293D to stepper motor because i think the circuit diagram for both the figures is different as given in the tutorial. i mean the pins are changed so if anyone can provide me a correct circuit...
thanks....

For creating the hex file you'll have to use an assembler.
Here's a free one that'll do the job quite well.. http://www.metaice.com/ASM51/Files/ASM51.zip

Interfacing steppers with the L293D is also shown in the tutorial.Have a look again.

hi...
thank you very much for your king help.
But still i have problem in obtaining a hex file
Can you please check this ASM file and convert and send the HEX file to me.
My mail id is rits_ritesh@indiatimes.com

It is a program to control two stepper motor and i got the idea of this program from the tutorial section.

I really got a lot of information about microcontroller and stepper motor from this forum.

thanks,

Regards,
Ritesh.

Hello Rits,

here's the compiled Hex file :

Hi Rits...
for assembling the asm source with ASM51 you would need to include the "reg51.inc" file in your ASM51 directory.
Unzip the attached file and copy it to your ASM51 directory.In your ASM source just add the following as the 1st line of your code : $include(REG51.inc)
Now run ASM51 from the command line like this : asm51 testfile.a51
and you're done.
