I am looking for a stepper control chip. There are some
good chips for DC motor such as National LM628, but only a
few step motor control chips which can not meet my
requirement: 100k pulse rate, changing parameters
(speed, target position) on the fly. I would appreciate if
anyone can give me some help.
Thanks.
