Hi All,
Can anyone give me circuit schematic of interfacing single phase 12V DC stepper motor with Spartan 3 fpga.
Let the circuit be simple and efficient. May use Opto coupler IC's for protection. Also all the components in the circuit should be easily available locally.
Thanks,

I think it is difficult and very slow for a 8051 do this task.
Usually you'll need a multiplier, and that is by nature, slow.
In addition, Have you tried to generate a simple triangular signal?
In that case you need only make add and subtractions, that's slow too.
Unless you need very slow signals, you'll need others "th

The fpga I/O pins tolerate relatively low voltages and currents, around 3.3V and 25mA (see the data sheet).
You need a separate 24V power supply and some interface circuits to switch the motor's higher voltage and current.
