Dear Mr. Field

I've made a complete cicuit for customer to drive a stepper mottor high wanted high speed and precise stoping but now he is not intersted in it

the circuit is driven by either serial port PC or another serial ( another circuit) the stpper motor was 200 steps/rev the rotating speed was about 4000 r.p.m ofcourse there is acceleration and deacceleration which can be set initially and distance is expressed by word (16 bit) with speed stepes 255 speed (200-4000 r.p.m) Left and right bit if you're intersted my email is mmardini@gmx.net

Best regards
