Pfft, no. I'm not going to criticise someone else for falling into that=20
particular beartrap. Certainly not when I've fallen into it more times=20
than I dare count.

"Oh, cool, this battery meter chip has a claimed 1% accuracy! This=20
should be cool to play with!"
*orders =A315 worth, plus support components*

And under the calibration section in the data sheet...

"All parts must be calibrated after assembly onto a final board with=20
their associated battery. In order to do this, the Evaluation Kit is=20
required."

And the website FAQ:

"The Calibration algorithms are currently considered a trade secret and=20
are not available for use with standard I2C host adapters, e.g. the=20
Aardvark and Beagle series."

So I ended up plunking down another =A380 for the I2C HA the evkit=20
software needs to talk to the chip. There isn't anything remotely=20
special about it, it's a TI MSP430 micro mated to an FTDI USB bridge chip..=
