+Known issues
+------------
+
+.. _ide_clion_knownissues_inopde_not_supported:
+
+Arduino ``.ino`` files are not supported
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+CLion uses "CMake" tool for code completion and code linting. As result, it
+doesn't support Arduino files (``*.ino`` and ``.pde``) because they are
+not valid C/C++ based source files:
+
+1. Missing includes such as ``#include <Arduino.h>``
+2. Function declarations are omitted.
+
+Convert Arduino file to C++ manually
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+For example, we have the next ``Demo.ino`` file:
+
+.. code-block:: cpp
+
+    void function setup () {
+        someFunction(13);
+    }
+
+    void function loop() {
+        delay(1000);
+    }
+
+    void someFunction(int num) {
+    }
+
+Let's convert it to  ``Demo.cpp``:
+
+1. Add ``#include <Arduino.h>`` at the top of the source file
+2. Declare each custom function (excluding built-in, such as ``setup`` and ``loop``)
+   before it will be called.
+
+The final ``Demo.cpp``:
+
+.. code-block:: cpp
+
+    #include <Arduino.h>
+
+    void someFunction(int num);
+
+    void function setup () {
+        someFunction(13);
+    }
+
+    void function loop() {
+        delay(1000);
+    }
+
+    void someFunction(int num) {

+
+* ``-D USB_HID``
+* ``-D USB_SERIAL_HID``
+* ``-D USB_DISK``
+* ``-D USB_DISK_SDFLASH``
