    NOTE: The emWin library cannot be used in the online compiler for legal
          reasons. You have to export the project and then follow the instructions
          below to download emWin and then modify your local project.
    How to get it
    The library must be downloaded from the page above and at the time this
    document was written the latest version was emWin 5.24h with the direct

    folder. After extracting the archive, the emwin/ folder should contain the

    The the 5.24h version (and possibly other later versions as well) is missing
    PNG support but the manual (available on the linked page above) has instructions
    on how to add it. Download and extract it
    into the png/ folder. After extracting the folder should contain one or more
    version folders. This is what the png/ folder may look like:
    Delete the version that you don't need (probably the oldest one).
    Updating the project
    When this project was exported it did not have the correct paths and files
    needed by emWin (for licence reasons). This is what you have to do in your
    IDE to get it to work:
        Keil uVision 4:
        1) Open the project
        2) Select the Project->Manage menu
        3) Add a new Group "emLib"
        4) Add all DMemWin/png/emWin_V5.28/GUI/PNG/*.c files "emLib" group
        5) Add DMemWinGUI/emwin/emWin_library/Keil/emWin_M4.lib to the "emLib" group
        6) Close the dialog
        NXP LPCXpresso IDE:
        1) Open the workspace
        2) Import the project from the exported zip file
        3) Right-click on the DMemWin folder in the Project Explorer and select Refresh...
		4) Right-click on the project name and select Properties...
			a) "C/C++ General" -> "Paths and Symbols" and select the "Library Paths" tab. 
			b) Click the Add button 
			c) Copy-paste the following into the dialog box: 
			d) Make sure that the "Is a workspace path" option is selected and click OK 
			e) Switch to the Libraries tab 
			f) Click the Add button 
			g) Copy-paste the following into the dialog box: 
			h) Click the OK button until all dialogs are closed. 
        Other IDEs:
        Do the corresponding actions for your IDE but remember to use the correct
        library file.
        If the IDE doesn't get the paths correct by the exporter then you might have
        to add the following to the include path:
