Energia two axis joystick with pushbutton demonstration

Joystick_demo.ico

/*
 Read Joystick and Push Button - display result to serial monitor
 Tested with the Texas Instruments MSP540F5529LP LaunchPad using Energia
 and an Addicore joystick with push button:
 https://www.addicore.com/Dual-Axis-XY-Joystick-Module-with-Push-Button-p/139.htm

 Note: The pin connections shown below will work with most MSP430 LaunchPads.
 The maximum values of xValue and yValue will depend on the Analog Digital
 Converter (ADC) - e.g. the F5529 is 12 bit (0 to 4095) while the 430G2
 is 10 bit (0 to 1023).
