Encoder use & Basic Stamp
Archiver
Posts: 46,084
Hi Norm,
If its the one I think you're referring too I found it on the N&V
site. If you have another example of encoder use please let me
know the link to it.
Yahoo wouldn't let me email you, it keep asking me to loggin
so apologies for the late reply.
Do you know of any encoder dedicated IC's do the counting,
and determination of direction?
I'm looking at another encoder app, actually glass scale where
the output signal goes down to 1 uS, I'd like to count it with
an IC or something and output the count to a BS2.
Actually I can slow down the output to about .2 mS if I don't move
it so fast, wonder if the BS2 can XOR fast enough to keep up with
that?
Thanks,
Mark

Try www.usdigital.com, they have encoder chips that will interface with
microcontrollers as well as encoders.
I hope this helps some.

Thanks for the tip, I've been aware of US Digital too, but
the new thing about them, at least to me, is that they're now
selling IC's. Those LS7083/84's might be great for a cheapo
stamp to encoder interface.
I'm thinking about getting one of those newer faster stamps
with all the pins since the BS2 I have now seems barely able
to keep up with hand turned Grayhill Series 61 2 bit quadrature
in a knob select app.
Right now I'm looking at a Heidenhain ST 1271 Length gage, its
pretty cool ± 1 µm accuracy(think that's a little less than half
a tenth"), pins 4 & 12 are Vdd, and 2 & 10 Vss (I don't know how
anyone can understand that european pictograph pinout diagram) and
you get nice TTL signals (signal period= 2 µm) outta the other pins.

Trouble with this thing is that its 500 bucks, it took a little
convincing to get the boss to let me get my hot little hands on it!

Don't quote me or buy anything on this info but
I think .0001" = 2.54µm, I think they call them "microns"
or millionths of a meter.

You are quite correct about the BS2, it cannot keep up with the count
frequency of almost any quadrature encoder of decent resolution. ·If you are
considering one of the newer and faster versions such as the SX then you may
have a shot at it. ·The code posted in the Nuts and Volts article, I believe
it was by Scott Edwards, should still work, maybe with some minor
modifications. ·The name of the article was SPIN AND GRIN I think. ·I used
that code with a BS2, with some minor changes since I was interfacing with VB
6.0 Pro, but it could not keep up with the 100 pulse per revolution FANUC
pulse generators (these are just FANUC quadrature encoders with a hand turned
knob mounted on them) unless you turned the knob VERY slowly. ·If you turned
slow enough, it would count correctly but not suitable for any real life
applications in this case.

1 µm = 10^-6 meters, or 1 millionth of a meter.
