OK now the details.
6. Send to a MAX232 devices and wallah, RS-232. OK
5. serialize
OK
4. A/D (convert from anlalog to digital) How? What
components?
3. S&H (sample and hold: buffer) How? What
components?
2. Integrate
How? What components
1. Take the analog RCX output How? What
components?
However, I need help on the component selection and design side.
----- End of forwarded message from Bill Flanagan -----
I'll do what I can but I really don't have the time right now to take on
*another* project. But feel free to ask questions...:)
First let me say that these above conversion steps are all well documented
in the literature. There are both discrete and integrated solutions
available.
Most manufacturers sell componants that S&H, integrate, serialize, etc. One
of the best ways I've found is to contact your local electronic wholesalers
and ask to visit their catalog room. It has been my experience they will be
more than happy to provide many databooks for free. If you have a real
business, or at least a DBA, it is much easier and they will waive fees for
such sets as from Intel. I generaly take away anywhere from a dozen to a
pick-up truck load full. In particular you want to ask about any
applications manuals or books they have available. Most chip manufacturers
(National's is excellent as is Motorola's) print these by the oodles. There
are various applications data sheets as well available on a component by
component basis. Data sheets are usualy free and can be ordered via phone.
Rather than provide a list of specific componants, when there are hundreds
of equivalent components on the market, I'd rather provide a list of
reference books that I have in my library. They should in general be
available either new or through used book stores.
The best (and it covers all of the above) is:
