[sdiy] A uC question and a circuit for those who need it.

[Batz Goodfortune]

Y-ellow All.
         It's coming into winter time. I get erratic in the winter time. So 
expect delays.

But before I disappear up my own bunghole, I seek the opinion of some uber 
programmers out there.

I need to make a decision on a suitable embedded controller for a synth 
application. To control and produce some wave forms. It seems to me that 
I've got 3 choices for candidates.
1) an AVR
2) a strongARM or freescale or whatever they're calling them these days.
3) a 400 meg MCS51 derivative.

An AVR would probably do the job but I'd undoubtedly need 2 of them. And 
quite a bit of glue. Suggestions of a suitable version would be handy.
An ARM derivative would have more peripherals on board than I'd ever need 
but would be plenty powerful enough. I've never worked with them so I'd be 
interested to hear of anyone who hates them or otherwise. I'm not sure what 
resources I'd need to gather to work with one either.
One of those MAXIM MCS51 derivatives I should be able to work with but 
they're a bit out of the relm these days. Even the fast 400meg ones. And I 
don't know what the 16 bit ones are like.

Any suggestions would be greatly appreciated.
---------------------------------

SECONDLY: And the person or persons who were talking about this will 
probably miss this being way down here. BUT!

By going to the following URL and clicking on the ETI circuits icon and 
following your nose, you'll find a circuit for transferring a signal, 
linearly through an opto isolator.

http://all-electric.com/b&c.html

It uses a pair of 567 tone decoders as PLLs to generate and translate an FM 
signal. It's pretty cute. And it would probably have a couple of zillion 
other applications as well. I know it's been a while since who ever it was, 
was talking about this, but it's taken me this long to find this stuff and 
get it up there.

There are also a half dozen other circuits from the old ETI trove up there 
that may be of interest. And I'll add more as time permits.

Hope this helps. And thanks in advance.

Be absolutely Icebox.
