 * \section intro1 Introduction
 * In addition to the graphical user interface and the commandline interface, STM32CubeProgrammer offers a C++ API
 * that you could use to develop your own application and benefit of  wide range
 * of features to program  STM32 microcontrollers memories (such as Flash, RAM, and OTP)
 * either over debug interface or bootloder interface (USB DFU, UART, I²C, SPI and CAN).
 *
 * This documentation details all types and functions API to use STM32CubeProgrammer functionalities. \n
 *
 * \section include STM32CubeProgrammer API package
 * The API package is based on the following resources that are ready for use : \n
 * <table>
 * <tr><th>File                                 <th>Description
 * <tr><td>CubeProgrammer_API.h                 <td>header file contains functions declarations and macro definitions to be used by the CubeProgrammer_API.dll.
 * <tr><td>DeviceDataStructure.h                <td>header file contains macro definitions to be shared between several functions.
 * <tr><td>CubeProgrammer_API.dll/.so/.dylib    <td>Dynamic Link Library file contains a library of functions and other informations that can be accessed by windows, linux and MacOs programs.
 * <tr><td>CubeProgrammer_API.lib               <td>import library for use with MSVC compiler.
 * </table>
 *
 * \section app Application System requirements
 * We offer various examples developed for use with Visual Studio and Qt Creator IDEs:
 *  -   Visual Studio project for windows applications under MSVC compiler.
 *  -   Qt project for Windows, Linux and MacOs applications under MinGW compiler.
 * \note The attached examples are tested on STM32F429, STM32L4R9 and STM32L452RE Nucleo Boards.
 *
 * \subsection windows Windows build settings
 * To ensure the correct environment for the provided examples, some constraints must be taken into account\n
 *
 * \subsubsection vs Visual studio
 * The code was developed with Microsoft Visual Studio Community 2017 version 15.6.6 with Windows SDK version : 10.0.16299.0
 * and it was tested also on Microsoft Visual Studio  2010 \n
 *  -   Verify that the api's lib directory is the default working directory.
 *  -   The debug command is to execute the application that is resided in the output directory.
 *  -   Insert the Additional Include Directories:\n
 * <HR>
 * \image html link1.jpg \n
 * <HR>
 *  -   Indicate the output name and path. \n
 *  -   Insert the Additional Library Directories. \n
 *  -   Insert the Additional Dependencies, The CubeProgrammer_API import library "CubeProgrammer_API.lib" must be added to Linker input\n
 * <HR>
 * \image html link2.jpg \n
 * <HR>
 * \note The provided Visual studio project is already configured like the description above and you can change it carefully according to your use case.
 * \subsubsection qt Qt creator
 * The Qt projects are developed with Qt Creator 4.7.1, Qt 5.11.2 and MinGW 32 bit compiler and also it can be compiled by MinGW x64.\n
 * <b> The shadow build option must be disable to inform Qt that the build should be located in the original Qt project directory. </b>
 * \note Verify that the following DLLs are placed to /lib in the api package directory :
 * <table>
 * <tr><td>CubeProgrammer_API.dll   <td>FileManager.dll     <td>STLinkUSBDriver.dll
 * <tr><td>HSM_P11_Lib.dll          <td>libeay32.dll        <td>libgcc_s_dw2-1.dll

 * <tr><td>mfc120.dll               <td>msvcp120.dll        <td>msvcr120.dll
 * <tr><td>Qt5Core.dll              <td>Qt5SerialPort.dll   <td>Qt5Xml.dll
 * </table>
 *
 * \subsection qtlinux Linux build settings
 * To correctly build the Qt project in linux platform, you should follow the next 3 steps:
 *      1. Select the build configuration in Projects field of the main view. \n
 *      2. Disable the Shadow build option. \n
 *      3. Go to build environment, add the System Environment variable LD_LIBRARY_PATH and set the path to ../../../../lib \n
 * <HR>
 * \image html LdLibraryPath.png \n
 * <HR>
 * * \note Verify that the following Shared Objects are placed to /lib in the STM32CubeProgrammer package directory :
 * <table>
 * <tr><td>libCubeProgrammer_API.so     <td>libCubeProgrammer_API.so.1      <td>libSTLinkUSBDriver.so   <td>libFileManager.so.1
 * <tr><td>libhsmp11.so                 <td>libQt5SerialPort.so.5           <td>libQtXml.so.5           <td>libQt5Core.so.5

 * </table>
 *
 * \subsection qtMacOS MacOS build settings
 * To get the default api folder that is integrated into the STM32CubeProgrammer package already installed, go to \n
 * /Application/STMicroelectronics/STM32Cube/STM32CubeProgrammer/STM32CubeProgrammer.app/contents/MacOs/api
 * \note Verify that the following Mach Objects are placed to /Application/STMicroelectronics/STM32Cube/STM32CubeProgrammer/STM32CubeProgrammer.app/contents/MacOs/bin in the STM32CubeProgrammer package directory:
 * <table>
 * <tr><td>libCubeProgrammer_API.dylib      <td>libCubeProgrammer_API.1.dylib       <td>libCubeProgrammer_API.1.0.dylib     <td>libCubeProgrammer_API.1.0.0.dylib
