Hello dear  all,

I am designing a Impedance Matcher for high power RF generator using 
FPGA.
As a result, I would like to know how to interface FPGA with stepper 
motor driver.
Please would you  brief me  about the interface circuit between FPGA and 
stepper motor driver as well as RF sensor?
Would you hand it me in case you have any interface circuit?
Thank you  in advance for your help.

Which FPGA? What stepper diver? And what kind of "RF sensor"? What 
signal interface does this unknown sensor provide?

Dear Lothar,
I really appreciate your concern. Thank you alot
I am going to use the following:
1. Xilinx spartan 6 FPGA
2. FTD3S2P22 Servo motor driver which is DC24V.
3.Sorry, I haven't selected which RF sensor I am going to use yet. Would 
you mind considering any Rf sensor you may think it fits for impedance 
matcher design?
Thank you again

That should be the very first step.

See it the way I (and everyone else reading your post) must see it: I do 
not know how your specific (and secret) impedance matcher is set up. 
And therefore I obviously cannot suggest any kind of sensor...
