3.19 Gyro Sensor
The gyro sensor(MPU3050) can sense angular velocity not gravity and accelerated motion. The gyro sensor
applied in LG- P970 can detect 3-axis rotation force sensing X,Y and Z angular velocity. And the gyro sensor
data is supplemented by the motion sensor data. It make possible user to development application SW using
gyro sensor data like that motion games.
U103(SUB_FPCB): MPU3050 IC is interfaced to OMAP3630(U301) using I2C interface.
