* ************************************************** **************************
* RP6 ROBOT SYSTEM - RP6 CONTROL M32 Examples
* ************************************************** **************************
* Example: Buttons and Beeper
* Author(s): Dominik S. Herwald
* ************************************************** **************************
* Description:
* This Example shows how to use the keys (and the beeper) on the RP6 Control
* board.
* We simply poll for pressed keys and output ADC value and key number on the
* LCD and serial interface, set some LEDs and play sounds with the beeper.
* You can use this program to get the real ADC values for your keypad.
* (They are different on each board, because of the 5% tolerance resistors.
* You may need to adjust some values in the RP6ControlLib in the
* getPressedKeyNumber() Function)
*
* ################################################## ##########################
* The Robot does NOT move in this example! You can simply put it on a table
* next to your PC and you should connect it to the PC via the USB Interface!
