To install the libraries:

• copy Library Directories to your \arduino\hardware\libraries\ or arduino\libraries directory
• Restart arduino IDE

• Each library comes with a simple example. You can find the examples in menu File->Examples

• go to directory of sketch and type make.

• mkdir build

• cd build

• cmake .. -DBOARD=mega -DPORT=/dev/ttyUSB0 You can select from mega/mega2560. If you have arduino installed in a non-standard location you by specify it by using: -DARDUINO_SDK_PATH=/path/to/arduino ..

• make (will build every sketch)

• make ArduPlane (will build just ArduPlane etc.)

• make ArduPloat-upload (will upload the sketch)

  If you have a sync error during upload reset the board/power cycle the board before the upload starts.

Getting the Source:

    assuming source located here: /home/name/apm-src
    You can either download it or grab it from git:
    git clone https://code.google.com/p/ardupilot-mega/ /home/name/apm-src

Generating the Eclipse Project for Your System:

    mkdir /home/name/apm-build 
    cd /home/name/apm-build
    cmake -G"Eclipse CDT4 - Unix Makefiles" -D CMAKE_BUILD_TYPE=Debug ../apm-src -D BOARD=mega -D PORT=/dev/ttyUSB0

    Note: Unix can be substituted for MinGW/ MSYS/ NMake (for windows)
        (see http://www.vtk.org/Wiki/Eclipse_CDT4_Generator)

    input options:

        CMAKE_BUILD_TYPE choose from DEBUG, RELEASE etc.
        PORT is the port for uploading to the board, COM0 etc on windows. /dev/ttyUSB0 etc. on linux
        BOARD is your board type, mega for the 1280 or mega2560 for the 2560 boards.
        ARDUINO_SDK_PATH if it is not in default path can specify as /path/to/arduino
    
Importing the Eclipse Build Project:

    Import project using Menu File->Import
    Select General->Existing projects into workspace:
    Browse where your build tree is and select the root build tree directory. 
    Keep "Copy projects into workspace" unchecked.
    You get a fully functional eclipse project

Importing the Eclipse Source Project:

    You can also import the source repository (/home/name/apm-src) if you want to modify the source/ commit using git.

Settings up Eclipse to Recognize PDE files:

     Window > Preferences > General > Content Types. This tree associates a
        filename or filename pattern with its content type so that tools can treat it
        properly. Source and header files for most languages are under the Text tree. 
        Add "*.pde" as a C++ Source.

Autocompletion:

	Right click on source project -> Properties -> Project References -> apm-build Project

Advanced:

    * Regenerating the eclipse source project file:
        cmake -G"Eclipse CDT4 - Unix Makefiles" -DECLIPSE_CDT4_GENERATE_SOURCE_PROJECT=TRUE /home/name/apm-src

• cd build
• cmake ..
• make package
• make package_source
