Macro Definition Documentation

◆ MAX_CACHE_COUNT

#define MAX_CACHE_COUNT ((MAX_TEMP_VARIATION / MAX_CAL_TEMP_DIFF) + 1)

Examples: example_service_calibration_caching.c.

Definition at line 66 of file example_service_calibration_caching.c.

◆ MAX_CAL_TEMP_DIFF

#define MAX_CAL_TEMP_DIFF (16)

A sensor calibration is valid at the temperature it was done +- 15 degrees

If the temperature isn't controlled during caching, which is the case in this example, the maximum amount of caches needs to be calculated from a temperature difference of 16.

For example

A calibration is done at 25 degrees, which means it is valid between 10 and 40 degrees
The temperature changes to 41 degrees
A new calibration needs to be done at 41 degrees since it is above the valid range for the previous calibration
The new calibration is then valid between 26 and 56 degrees

However, if the temperature is controlled, for example in a factory, the maximum amount of caches can be calculated from a temperature difference of 30.

For example

A calibration is done at 25 degrees, which means it is valid between 10 and 40 degrees
The temperature is manually changed to 55 degrees
A new calibration can be done which is valid between 40 and 70 degrees

The maximum temperature variation that the application will operate in is assumed to be -40 to 85 degrees in this example.

Returns: Returns EXIT_SUCCESS if successful, otherwise EXIT_FAILURE

Test if measure on wake up is enable Do a measurement if the the detector is ready (configured and calibrated)

Detector filters and states are reset on prepare (reconfiguration) to avoid risk of false detections when switching back to a zone.
