stepper motor drive usingavr

[nipun]

i controlled a stepper motor using l293d ic and atmega16 its working fine but is quite slow if i try to increase its speed it gets saturated and stalls i heard sumthing like current chopper drive for stepper motor but dont know what is it exactly,sumone used it n is getting better performance can sum body help me out

that is the maximum speed of your stepper, the sound come because the stepper is missing the sequence. There should be some delay between two sequence. If the delay is less than delay(min) then the motor will lose sequence. Remeber speed is inversly proportional to torque in stepper. My stepper delay(min) was around 4ms.
