control of stepper motor

Posted: Sunday, 16 January 2011 by moutaz in التسميات: Collectors

this is circuit consist of l297/l298

by this circuit we can control by stepper motor through parallel cable

so it wanted from software group if can send data at parallel port

that is mean more cheaper circuit and will not need to buy progammable to program pic

to get datasheet make search on l297

This application note describes how to implement an exact linear

speed controller for stepper motors .

In This Link There is PDF That Can
explain what this mean exactly .
