Hi friends, Hi was designed the stepper motor controller through 89S52. The port 1 pins (1 t0 8) are used as input port (digital datas from 8- bit ADC 0804). pin 12 is connected with the INTR (active low) pin of the ADC, pin 21 is fed to the Write (WR) (Active low) pin of the ADC, and pin 22 is fed to the Read (RD) pin of the ADC. The pins 25,26,27,28 of the port 2 is deriven to the stepper motor driver ULN 2003A. Any budy have sample program for working this circuit? Actually i'm a beginner in 8051. thank u. with regards... |

thank u.
you are an eternal optimist "this circuit", the likelyhood that anyone has it with thet particular pinning is about 1:10000000.
if you can not yourself code this up to a reasonable level (this is the only way you will ever undersatnd a "sample program", you are totally lost
it seems that this is the time for final papers, are you not supposed to do your coursework yourself?
if you actually in tend to do some work on this, show your code, state your problem and help will NOT be forthcoming as long as you specifically thank Mr. U, if you try to thank whoever instaed you may have a chance.
