Stepper motor

Hello, I m using Stepper motor in my verilog code to control full,half and microstepping modes. I have achieved full and half steps successfully but i don't know how to write cod...

Microstepping involves the ability to send variable phase currents to the motor. This is achieved by analog or current controlled PWM output stages. Do you have it and what's their hardware interface to the FPGA?

I have attached one block for my stepper motor interfacing in which (stpr_motor_cntrl1 to stpr_motor_cntrl4)..this signals,i m writing my sequence (like 0011,1001 etc).And output from the driver ckt is connected to the four windings of the motor.So how to do for microstepping?

As u suggested,how to to using PWM,if you have any sample code for any circuit for microstepping and some reference document for the programming or any website.Kindly tell me.

thanks
