Building own stepper motor driver

[embpic]

hello masters
i have stepper motor driver with L293D but this is very noisy and provide very less micro-stepping but for my project i need to have more micro-stepping. i need 1600 or 3200 steps per revolution. so how to build own stepper motor driver by controlling current using controller.

i have read regarding current need to be control for micro-steeping if any one know give some guidline. how to make driver to have micro-stepping.

thank you.
