I am running on 150ma watch batteries, it had to be real small. I get about 10 runs at 2 hours on it. Which is not the end of the world. But I had that
LDR circuit and you mentioned doing it.. I did it on the 12F509, fired right up..
I was real careful soldering the xtal as well, barly touched it with the iron..
I will get the scope out later and see if it there is 32Khz on the chip.
I know with some microcontrollers, they have a speed range and that is it.
I googled for Atmel 1200 and Khz and did not see anyone else doing it as well.
The 1200 is pretty ancient - It's probably Atmel's equivalent to the 16F84... From it's data sheet, it says it can operate down to DC, but using a 32KHz crystal will probably require some tuning - and power limiting.
I stumbled across this appnote on tuning fork crystals, it has some sample 32KHz oscillators, with parts values, and the reasoning behind the choices.
