|
* 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.
