Mini2440 and linear actuator

Dear all, are there anyone who tried to use mini2440 to pilot a linear
actuator under linux? 
Thanks

Marco,

Yes: Using the serial port and a motor controller board.  I got a serial
port adapter for ttySAC1 since the primary serial port was tied up with the
debug console.  To my knowledge there is not a way to drive a stepper/servo
motor directly since the board does not have the proper drive support.  If
you want to create your own low level drive code, I would recommend you use
the GPIO outputs to interface to a motor driver stamp.  Search ebay for
"L293" and you will find motor driver chips which can be driven by ttl
signals.

Thanks for your suggestion

Can you share the circuit diagram for interfacing a servo motor with
