Could you possibly post a picture of your circuit? When first testing
my ARMmite with a photo-resistor circuit I got about 128 drift with a
10ms capture rate. To me this seems adequate and is on par with other
microcontroller boards I have used(Basic Atom, PICAxe). For
applications where I need noise rejection and precision I have never
replied on built in AD's and just used external chips.

Is this post addresses to me or Bruce ? I would post my circuit, but
Bruce's is proably going to be more useful. My circuit is made up on
breadboard so that my clumsy soldering doesn't destroy the ARMmite and
so that I can easily modify it.

Also, how do you post pictures/graphics in this forum ?
