Smart Thermometer + Spirit Level for the FRDMK64F Device

This program displays the temperature in Celsius and Fahrenheit and allows the user to set a "temperature alarm" that activates once the the temperature exceeds a temperature value specified by the user.

This program also displays graphical "spirit levels" showing degrees of rotaion along 3 axis.

The user can cycle between screens using sw2 and sw3 buttons, set the temperature alarm by pressing up and down on the joystick, control the volume of the alarm with the pot1 knob, and control the time value of the wait function by pressing left and right on the joystick.
