Controlling the cuurrent by a PIC?!

[AlexNadal]

I want to drive some stepper motors and I´m thinking to control their currents with a PIC (also becouse I´m going to use a PIC to control each motor) so

what do you think? Use a PIC to control the current limit or use a simple circuit as something as easy as a resistor or something more complex as using a LM117?

Thanks
