Hi all,

At present i am working on hal part of sensors in android sdk, we are using 3- Axis BMA-150 Accelerometer sensor to get acceleration values with respect to X,y,Z Axis, I want to know whether this sensor will give o/p directly in SI units by using some calibration techniques or what ? , and i noticed that in sensor.c file they mentioned

720.0 LSG = 1G(9.8 m/s2), what is the relation between LSG and acceleration due to gravity? what is meant by LSG

why they are multiplying the o/p of accelerometer x,y,z valuse with 9.8/720.0f . please help on this part .

Thanks Vinay
