USB Unipolar 3 in 1 Motor Stepper Controller

This is a usb controller for 3 engines unipolar step by step, you can move completely independent, and in terms of speed of rotation sense and the coordinated which should be.

The position of engine can take value between -2147483648 and 2147483647
Minim velocity = 0.015 steps/second
Maximum velocity = 1000 steps/second

Here i posted a brief presentation of the controller in the prototype phase, it will arrive in stores in a short period.

It is designed around an ATmega8 microcontroller with USB1.1 software interface and drivers that are used is ULN2003

This is the interface for the PC, to control in real-time the controller:








And this is the prototype controller board:


















In the next image is described command method :

From Digital electronics and programing

Update for PC program, add new function:
