I need some help to read data from the accelerometer sensor included in i.Mx53 QSB.

I've installed the mma8450 device driver and during system boot I can see this messages:


check mma8450 chip ID
mma8450 0-001c: build time Jul  1 2011 08:22:07
input: mma8450 as /devices/virtual/input/input3
add mma8450 i2c driver


Now, how can I read data from each axis, and how can I set sensor configuration (eg.: change sensivity)?


Thanks in advance!
