+/* Hexi_Acceleromagnetic_Synth
+    2017 Michael Yarnell, Alec Pierce
+    Class Project: ECE49500 SP17 (MEMS/NEMS/IoT/Wearables)
+    IUPUI - Purdue School of Engineering and Technology
+
+ The following program turns an NXP Hexiwear, its development board, and a Click
+  buzzer collectively into an 'acceleromagnetic' synthesizer. That is to say
+  that the synthsizer is controlled primarily via the onboard accelerometer and 
+  magnetometer units.
+ Once the appropriate initializations have been made, the program plays a short,
+  preprogrammed tune.  If, at any time, the left or right screen buttons are
+  pressed, they each emit unique "drumbeat" note sequences.  The accelerometer
+  and magnetometer are read.  The accelerometer x and y (pitch and roll, 
+  respectively) control note selection.  The magnetometer value RMS is
+  calculated, and if the magnetic field RMS is greater than 250uT, the 
+  instrument will emit corresponding notes.
+
