Yes, software provided with practiSPIN allows running stepper motors in microstepping mode using the L6208 with 16 microsteps per step. You need two DAC to implement microstepping. In the practiSPIN system, two PWM outputs from the ST72264 are used as a simple DAC by filtering the output and applying that voltage to the Vref pins of the L6208.
