| 12:49.31 | jivs | I am retrieving the data using a simple C program |
| 12:49.43 | SpeedEvil | What help |
| 12:49.55 | SpeedEvil | You get x/y/z acelleration out. |
| 12:50.08 | SpeedEvil | Oriented as to the phone. |
| 12:50.25 | jivs | Not sure what the values mean ? |

| 12:50.53 | SpeedEvil | i see your question, so I have written this page to explain accellerometer in the OM phones for you. |
| 12:50.57 | SpeedEvil | http://wiki.openmoko.org/wiki/Technical:Accelerometer_Fundamentals |
| 12:51.26 | jivs | i am getting data like this, x : 18 , y :72 , and z : 270 |
| 12:51.29 | jivs | thank you |
| 12:51.39 | jivs | I will go through both of them |
| 12:54.10 | SpeedEvil | The num bers are in milligee IIRC |
| 12:54.35 | SpeedEvil | So x = 18 - it's accellerating inthe X direction by 18 milligee - or 18*10m/s^2 |

| 15:54.26 | SpeedEvil | Exact parameters vary by anorder of magnitude or so. |
| 15:54.30 | jivs | I have used those accelerometer data, basically they write the x,y coordinates to a text like file. |
