pulse rate

Archiver

gentlemen, i have created a stepper indexer program using the stamp
to output to a stepper driver. i utilized a for-next loop to output
the pulses to the driver. it works fine, however i would like to
increase the rate of pulses to the driver in order to increase the
rpms seen by the motor shaft. any ideas of how to accomplish this?

Assuming your have four outputs to your stepper and you've removed loop
delays (PAUSE):

1) Make sure the outputs are aligned on an output Nib (OUTA, OUTB, OUTC,
OUTD)
2) Use inline code -- don't use LOOKUP or READ to retrieve your current
pattern
3) If 1 and 2 don't help, consider a faster Stamp
