AndyWarne:
A flight yoke would be an interesting application. It would not be as accurate as a pot though. The signal from an accelerometer when used as a position sensor is quite small and so considerable scaling up would ne necessary. It would probably work but no real reason to use it over a pot in this application.

Ummon:
Especially as it'd be far more expensive to.

Andy, is it easy to calibrate for 1g, 2g, etc with the UConfig?  Or does a 2 g-fore just send a value twice as high as a 1 g-force?

The scale factor and offset are set in the board using the U-Config utility, which has slider controls for these values. These are retained in the board. So there would not normally be anything to do in the app software. calibration for a certain G value might be a bit tricky as you would need some method of measuring this.

Shucks.  I was hoping it was something easy like the value sent with 0.5g was half the value sent at 1g, which was half of the value with 2g, etc: IOW linear.  (Hoping, not expecting.)

Calibrating for 1g and under isn't hard, as long as you can rotate the board, have a decent plump bob & protractor, and know about sin/cos.  But as you said, calibrating for stuff above 1g is harder.

Not that my current car can corner at over 1g, but I'd want 1g+ for my dream car. ;)
