| - | + | Fremantle offers the possibility to play with accelerometers. There is a plan to offer a proper interface for accelerometers in Maemo, but if you want to try out before there are a couple of ways to do it. | |

| + | == D-Bus == | ||
| + | |||
| + | Thomas Thurman ([http://twitter.com/marnanel marnanel]) has put together a simple demo of an application using accelerometers using the D-Bus interface. You can find sources and .deb up at http://people.collabora.co.uk/~tthurman/sandcastle/ | ||

| + | == sysfs == | ||
| + | |||
| + | Another way is to use the sysfs file information. | ||
| + | |||
| + | /sys/class/i2c-adapter/i2c-3/3-001d/coord | ||
| + | |||
| + | When reading that file you get 3 values X, Y and Z. Values are in mG (milli G). 1000 = 1 G | ||
| + | |||
| + | * On the table face up values are 0, 0, -1000 (face down would read 0, 0, 1000) | ||
| + | * On the table on botton side (landscape): 0, -1000, 0 | ||
| + | * On the table on right side (portrait): -1000, 0, 0 | ||
| + | * In any other position any mix of those 3 values. | ||
| + | |||
| + | These are theoretical values. In real life your mileage will vary. | ||
