Ron22,

You can change the logging interval to log around 250 tumes per second (more if you log fewer inpits) to 1 log per second by changing a text file which is read at boot up.

You'd have to modify the firmware to include some wait state loops, which is not a huge deal, but with all my projects was just too much resistance.

As microprocessors go, the arm is a good one and pretty powerful, but overkill if you want to read data at 30 minute intervals. This is actually what I wanted to do.

There's the AVR butterfly, which I think would be better.

You should check out this link.

And then this link.

Runs seven years on a tiny battery.

I think this is the answer to your prayers.
