Instructions: This test records the output from the DCM algorithm, as you move the board. The LEDs on the shield will blink rapidly for about 20-30 seconds while the sensors are calibrating, and then the data will start to display. The yaw data will probably drift a little, since that is only corrected by the GPS in motion and/or magnetometer (if you have one connected), and will typically not be valid on the benchtop.

Typical data while rotating board (roll, pitch, yaw):

Troubleshooting: If the values don't change as you move the board, you probably have an electrical connection problem, most likely due to a soldering error. Check your solder joints!
