Overview
========
The E-Compass demo application demonstrates the use of the FXOS8700 sensor. The tilt-compensated algorithm calculates
all three angles (pitch, roll, and yaw or compass heading).

Toolchain supported
===================
- IAR embedded Workbench 7.50.1
- Keil MDK 5.17
- GCC ARM Embedded 2015-4.9-q3
- Kinetis Development Studio IDE 3.0.0
- Atollic TrueSTUDIO 5.4.0

Hardware requirements
=====================
- Mini/micro USB cable
- TWRK80F150M board
- Personal Computer

Board settings
==============
No special settings are required.

Prepare the Demo
================
1.  Connect a USB cable between the host PC and the OpenSDA USB port on the target board.
2.  Open a serial terminal with the following settings:
    - 115200 baud rate
    - 8 data bits
    - No parity
    - One stop bit
    - No flow control
3.  Download the program to the target board.
4.  Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.

Running the demo
================
When the demo runs successfully, you can see the information below printed to the terminal.
Note: you must rotate the board 360 degrees to get the max / min value of the magnetic field.
