Stepper Motor to Stamp2SX
Archiver
Posts: 46,084
Hello Group,
I have a stepper motor that I would like to put onto my robot as
a drive motor. I am having some trouble doing so. I really do not want to
buy a control board if I do not have to. Does any one know how I could
control one with a Stamp 2SX? If any one has any information on stepper
motors and stamps, I would sure appreciate it if you could help me out here.
Thanks in advance. -Alex Burke

They should get you up and running. There is also a good application note in
the Basic Stamp manual under the BS1.

Tim gave you some excellent references. I would add the suggestion that you
check out the EDE1200 for unipolar steppers, or the EDE1204 bipolar stepper
IC from www.elabinc.com . These chips work quite well and make the software
much simpler if you have complicated control routines. They offer one pin
direction control, full or half steps via one pin, single stepping, or free
running at several speeds. The data sheets are available at their site.
Good luck,
Ray McArthur

stepper mototor off our stamp, it blew with only 5mA pulling through
it!!! There are very easy to pop as they are only PIC's and on top of
that, they are expencive. We wound up using a ripple counter and it
worked SOOO much better.

as advertised. Is $8.30 expensive for what they do?

Perhaps this fellow didn't read the first page of the datasheet, or view
the hookup examples? This chip (EDE1200, EDE1204) is designed to connect
through a drive circuit, such as the ULN2003A (for unipolar), or the L293D
(for bi-polar). This way, any size (voltage,current) of motor can be
used. We have many thousands of these IC's in production products with
virtually zero failure rate (except for the occasional prototyper who
accidentally swaps the 12V for the 5V line, or who doesn't read the
datasheet...)

I agree, Ray, and they work BEST after the FREE documentation is read,
and the circuity implemented as suggested !

Bruce
As a matter of fact, we built one, correctly, from the documentation
and schematics that came with the chip. We used the one from
www.elabsinc.com, unless there are two chips with the same name built
by different people. Anyway, neither me or my team were statisfied
with this chip. But we all have or opionions...
