 *
 *  Example of Zonik board implementation and simple operation: Infinite loop
 *  enablinkg the sensor and rading few times, acquiring the dBA of sensor
 *  The first value acquired is invalid, because it's in hw init state awaiting
 *  a valid internal reading.Once the driver is initialized, posterior readings 
 *  are valid.Finally in the loop disables the board with standard call and
 *  shows the error, and loop again enabling it.
