sensor_format_user_data

A format used for user data that's published as interim sensor data

Synopsis:

#include <sensor/sensor_api.h>

typedef struct sensor_format_user_data_t {
    uint32_t data_size;
    uint32_t data_id;
    int64_t publish_timestamp;
    uint8_t reserved[SENSOR_DATA_EXTENDED_SIZE];
} sensor_format_user_data_t;

Data:

uint32_t data_size: The size of the data, in bytes.
uint32_t data_id: Identifier for the type of user data.; Interpretation of this field is left to the user to define in his application and permits defining of different user data items
int64_t publish_timestamp: The timestamp when the buffer was filled.; The timestamp is referenced to the system monotonic clock (CLOCK_MONOTONIC).
uint8_t reserved[SENSOR_DATA_EXTENDED_SIZE]: The remaining bytes are left to the user to use to describe the user data.; It is recommended that the user casts a user-defined structure over this area that will depend on data_id.

Library:

libsensor

Description:

There is a basic structure that the user is free to expand to meet his needs.
