Dears,
please help me to control stepper motor driver controller L297 using Pic micro controller .
i need to generate the step and direction and enable .
how to do that ?
Thanks

the funny thing had happned ,
i did connected Enable o 5 volt , and set the direction . now when i only touch the step wire with my finger the stepper motor rotets ...... why ?
Thanks

thanks for your link , unfortuantly i'm not so good in assembly so i'm trying to find in C or PIC basic .
what if i wrote a code to generte puleses on thes step pin every 50 micro second , will it work ?
Thanks

Hello watzmann,
Your body acts a a receiver for any stray AF (50 or 60 Hz power line frequency) and/or RF in the vicinity. Your finger conducts that hodge-podge of frequencies into the CLOCK input of your L297. Whenenver the chip detects a rising edge, it will take that as a clock signal. Not very reliable and potentially dangerous...
All the best,
Fred
Is there a reason why you want to use the L297? It's a very old design. Better chips are available. The tb6560 requires no microcontroller. But you will need to make sure to follow the proper power sequencing.
