Data Definition

The input data structure of the sensor input module consists of four parts: sensor data x, y, z, and type. The data is provided for developers through callbacks.

Example:

1
2
3
4
5
6
struct SensorData {
    float x;
    float y;
    float z;
    int32_t type;
} __attribute__((packed));

The following sensors are available:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
enum VmiSensorType : uint32_t {
    HANDLE_ACCELERATION = 0,                // Acceleration sensor
    HANDLE_GYROSCOPE,                       // Gyroscope sensor
    HANDLE_MAGNETIC_FIELD,                  // Magnetic field sensor
    HANDLE_ORIENTATION,                     // Orientation sensor
    HANDLE_TEMPERATURE,                     // Temperature sensor
    HANDLE_PROXIMITY,                       // Proximity sensor
    HANDLE_LIGHT,                           // Light sensor
    HANDLE_PRESSURE,                        // Pressure sensor
    HANDLE_HUMIDITY,                        // Humidity sensor
    HANDLE_MAGNETIC_FIELD_UNCALIBRATED,     // Uncalibrated magnetic field sensor
    HANDLE_MAX = 10
};

The output data structure of the sensor output module consists of the sensor type handle and the sensor sampling rate. The data is provided for developers through callbacks.

Example:

1
2
3
4
struct SensorActivateData {
    int handle;             // handle corresponds to the value of VmiSensorType.
    int64_t samplingPeriod; // When a sensor is deactivated, this field can be ignored or set to the default value.
} __attribute__((packed));
