-
-## Camera Control Channel
-
-The channel provides get, set and query (min, max, default).
-
-## Half-Duplex Channel
-
-The channel only provides set, such as zero drift correction.
-
-## IMU Channel
-
-The channel is used to request and response IMU data, see @ref spec_imu_data.
-
-## File Channel
-
-The channel is used to read and write device information, image params, and IMU params.

+Get IMU data

+

+
+During capturing data, you need ``EnableMotionDatas()`` to enable caching in order to get IMU data from ``GetMotionDatas()`` . Otherwise, IMU data is only available through the callback interface, see :ref:`get_from_callbacks` .

+.. _get_with_plugin:
+
+Using the plugin to get data
+============================
+
+API provides a ``EnablePlugin()`` function to enable plugins under a path.
+
+Official provided plugins for calculating binocular parallax are now available in the `MYNTEYE_BOX <http://www.myntai.com/mynteye/s/download>`_ located in the ``Plugins`` directory.
+
+.. code-block:: none
+
+  Plugins/
+  ├─linux-x86_64/
+  │  ├─libplugin_b_ocl1.2_opencv3.4.0.so
+  │  ├─libplugin_g_cuda9.1_opencv2.4.13.5.so
+  │  ├─libplugin_g_cuda9.1_opencv3.3.1.so
+  │  └─libplugin_g_cuda9.1_opencv3.4.0.so
+  ├─tegra-armv8/
+  └─win-x86_64/
+
+* The ``linux-x86_64`` directory shows the system and architecture.
+
+  * You can find your CPU architecture from system information or ``uname -a``.
+
+* The library name ``libplugin_*`` shows the plugin identity and the third party dependency.
+
+  * ``b`` ``g`` is a plugin identifier, indicating that different algorithms are used.
+  * ``ocl1.2`` shows it dependence on ``OpenCL 1.2``, if it exists.
+  * ``cuda9.1`` shows it dependence on ``CUDA 9.1``, if it exists.
+  * ``opencv3.4.0`` shows it dependence on ``OpenCV 3.4.0``, if it exists.
+  * ``mynteye2.0.0`` shows it dependency on ``MYNT EYE SDK 2.0.0``, if it exists.
+
+First, select the plugins that you are going to use depending on your situation. If you relying on third parties, please install a corresponding version.
+
+Then, enable the plugin with the following code:
+
+.. code-block:: c++
+
+  auto &&api = API::Create(argc, argv);
+
+  api->EnablePlugin("plugins/linux-x86_64/libplugin_g_cuda9.1_opencv3.4.0.so");
+
+The path can be an absolute path or a relative path (relative to the current working directory).
+
+Finally, just call the API to get the data as before.
+
+.. tip::
+
+  If the plugin is not enabled, ``api->Start(Source::VIDEO_STREAMING);`` will automatically find the appropriate plug-in in the ``<sdk>/plugins/<platform>`` directory to load.
+
+  In other words, you can move the plug-in directory of the current platform into the ``< SDK > / plugins`` directory. To automatically load the official plugin, install the corresponding ``CUDA`` ``OpenCV`` plugin dependency, recompiling and then run ``API`` layer interface program.
+
+Before running, please execute the following commands to ensure that  the plugin's dependency library can be searched:
+
+.. code-block:: bash
+
+  # Linux
+  export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
+  # /usr/local/lib means the path of dependency library
+
+  # macOS
+  export DYLD_LIBRARY_PATH=/usr/local/lib:$DYLD_LIBRARY_PATH
+  # /usr/local/lib means the path of dependency library
+
+  # Windows
+  set PATH=C:\opencv\x64\vc14\bin;%PATH%
+  # add to PATH of system environment
+
+In addition, the following command can be executed to check whether the dependency Library of the plug-in can be searched:
+
+.. code-block:: bash
+
+  # Linux
+  ldd *.so
+  # *.so means plugin path
+
+  # macOS
+  otool -L *.dylib
+  # *.dylib means plugin path
+
+  # Windows
+  # please download Dependency Walker ，open DLL .
+
+If the plugin's dependent library is not found, it will report an error \"Open plugin failed\" when loading.
+
+Complete code sample, see `get_with_plugin.cc <https://github.com/slightech/MYNT-EYE-S-SDK/blob/master/samples/tutorials/data/get_with_plugin.cc>`_ .
+
+.. tip::
+
+  Linux can also add a dependency library path to the system environment, so that the compiled program can run directly. (does not require ``export LD_LIBRARY_PATH`` in the terminal then run again).
+
+  * Create a ``/etc/ld.so.conf.d/libmynteye.conf`` file and write the dependent library path.
+  * Execute the ``sudo /sbin/ldconfig`` command in the terminal and refresh the cache.
+
+  .. literalinclude:: ../../files/libmynteye.conf
