Energia two axis joystick with pushbutton demonstration
/*
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).
Joystick Pin F5529LP Label
-------- --- -------------
GND 20 GND
+5V 1 3V3
VRX 2 P6.5
VRY 6 P6.6
SW 5 P1.6
