Bogdan Davidoaia 6460e7655d samples: sensor: fxos8700: use floating point for printing sensor values Printing values as <integer_part>.<fractional_part> gives undesired results for negative numbers, so print the values converted to floating point to avoid this.

Title: fxos8700

Description:

A sensor application that demonstrates how to use the fxos8700 data ready
interrupt to read accelerometer/magnetometer data synchronously.

--------------------------------------------------------------------------------

Building and Running Project:

This project outputs sensor data to the console. It requires an fxos8700
sensor, which is present on the frdm_k64f and hexiwear_k64 boards. It does not
work on QEMU.

    make BOARD=frdm_k64f
or
    make BOARD=hexiwear_k64
