Re: Measure of the file /dev/input/event3 (Accelerometer data)
I think the Accelerometer data retrieval page on the wiki should have all the information you are looking for: http://wiki.openmoko.org/wiki/Accelerometer_data_retrieval along with several projects using the accelerometers that would be good reference points on projects.openmoko.org. Search for accel. Also the Google Summer of Code gestures project: http://wiki.openmoko.org/wiki/Gestures Good luck.

To me, it looks like they're in cm/s/s, i.e. divide by 100 to get the familiar value of 9.8ish pointing downwards. Don't forget that (a) I may be wrong, and (b) The orientation of the accelerometers might need some calibration.

Ok, Paul's code says that the number is in units of 1/1000 of 'g' (g=9.8 m/s/s), which also makes sense to me. So, I'll defer to his expertise unless anyone says otherwise :) Tom -- Thomas White - Downing College - Electron Microscopy Group (PhD Student), Department of Materials Science and Metallurgy University of Cambridge ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
