Re: [Gumstix-users] Accelerometers attached to gumstix

[Antoine <ant...@fr...>]

wasn't the question about accelerometers in the begining ?

I'v used dual axis analog device ADXL320 parts with succes ( analog 
output, so you'll need some ADC). Recently I started to use freescale 3 
axis MMA7260Q ( still analog output) and I'm also satisfied with them.
Here is a picture of a (ugly) IMU proto I made with ADXL320 and ADXRS300

Now, regarding measuring tilt using accelerometers alone, you might get 
into trouble due to the high level of vibrations found on rc heli - 
Solutions based on gyros+accell(+magneto) fused with some kalman filter 
tend to perform better.
