+// This software interfaces the Teensy 3.2 with a laptop pointing stick (aka trackpoint) that is not PS/2.
+// Raw trackpoints use a Wheatstone bridge configuration with 4 resistive strain gauges.  
+// The connections from the Teensy are 3.3 volts, ground, x voltage to A0, and y voltage to A1.
+// In the Arduino IDE, select Tools, Teensy 3.2. Also under Tools, select Keyboard+Mouse+Joystick
+//
+// Revision History
+// Rev 1.0 - March 28, 2020 - Original Release

+// declare and initialize variables  
+  int x_read; // stores the reading from the X ADC
+  int y_read; // same for the Y ADC
+  char mx; // signed byte used by the Mouse.move function for x value. Positive value moves to the right
+  char my; // positive y value moves down 
+  int x_delta; // signed 16 bit value gives x movement amount
+  int y_delta; // y version. 
+  int x_center; //resting position of x sensor
+  int y_center; //resting position of y sensor
+  int noise_zone = 175; // dead zone around the center. Increase this number if 
+                        // the cursor moves without touching the TP. Decrease if
