SIPL-based Image Sensors (Live)

Initialize the Sensor Abstraction Layer

dwSAL_initialize(&sal, sdk);

Create a client

dwSensor cameraSensor = DW_NULL_HANDLE;
dwSensorParams params;
params.parameters = "camera-name=SF3324,interface=csi-a,link=0,output-format=processed";
params.protocol = "camera.gmsl";
dwSAL_createSensor(&cameraSensor, params, sal);

after starting the sensor, the camera will start acquiring frames

dwSensor_start(cameraSensor);
 
while(loop) {

We read a frame, which is stored as a dwCameraFrameHandle_t and specify a timeout value in microseconds

...
    dwCameraFrameHandle_t frameHandle = DW_NULL_HANDLE;
    dwTime_t timeout = 33000;
    dwSensorCamera_readFrame(&frameHandle, timeout, cameraSensor);
...

we get an image with type DW_CAMERA_OUTPUT_NATIVE_PROCESSED.

...
    dwImageHandle_t imageNative;
    dwSensorCamera_getImage(&imageNative, DW_CAMERA_IMAGE_OUTPUT_NATIVE_PROCESSED,...);
 
    // CODE: use imageNative (maybe send to serializer)
 
...

return frames to the fifo

...
    dwSensorCamera_returnFrame(...);
}

stop the sensor and release

dwSensor_stop(cameraSensor);
dwSAL_releaseSensor(&cameraSensor);
