C Acceleration/Magnetometer Sensor
For development of applications that require orientation and movement tracking, a combined
accelerometer and magnetometer is provided (NXP FXOS8700CQR1). The sensor can support either
SPI or I
2
C interfaces but is used exclusively with the I
2
C interface on the R41Z Evaluation Board. When
in I2C mode, the address of the sensor can be set using external pull-up and pull-down resistors. The
signals used for the I
2
C bus are shared with the expansion headers. Because of the addressed nature of
I
2
C it is possible to use this same bus to connect to additional devices on a shield.
