The MMA8652 is a 12 bit, 3 axis accelerometer
A basic library for the MMA8652 accelerometer, provides data in either floating point G's or as a signed 16 bit integer.
Freescale's MMA8652FC Xtrinsic 12-bit accelerometer has industry leading performance in a small 2 x 2 x 1 mm DFN package. This accelerometer is packed with embedded functions that include flexible user-programmable options and two configurable interrupt pins. Overall power savings is achieved through inertial wake-up interrupt signals that monitor events and remain in a low-power mode during periods of inactivity.
