* Function: int pureDataCommunicate(void)*

* Output: None
* Overview: Reads the CDC port, and stores the read values on a
* buffer (inputData)it then routes the input data to
* functions that take care of specific actions.
* Note that the size of the arrays passed to this function
* correspond to the number of Pins available in the
* specific Pinguino. It also prints a 50 through the CDC
* when the button is pressed.
* Return: int dataLength - the length of the array received.
* Note: None
