24 /** \example example_detector_distance_with_iq_data_print.c
25  * @brief This is an example on how the Detector Distance API can be used
26  * @n
27  * This example executes as follows:
28  * - Retrieve HAL integration
29  * - Initialize distance detector resources:
30  * + Create distance detector configuration
31  * + Update configuration settings
32  * + Create Distance detector handle
33  * + Create buffer for detector calibration data
34  * + Create buffer for sensor data
35  * - Create and calibrate the sensor
36  * - Calibrate the detector
37  * - Measure distances with the detector (loop):
38  * + Prepare sensor with the detector
39  * + Measure and wait until a read can be done
40  * + Print IQ data amplitude
41  * + Process measurement and print the result
42  * + Handle "calibration_needed" indication
43  * - Cleanup:
44  * + Destroy detector configuration
45  * + Destroy detector handle
46  * + Destroy sensor data buffer
47  * + Destroy detector calibration data buffer
