alindvall 0:582739e02e4d 4 -----------------------
alindvall 0:582739e02e4d 5 According to http://www.lpcware.com/content/project/emwin-graphics-library:

alindvall 0:582739e02e4d 13
alindvall 0:582739e02e4d 14 NOTE: The emWin library cannot be used in the online compiler for legal
alindvall 0:582739e02e4d 15 reasons. You have to export the project and then follow the instructions
alindvall 0:582739e02e4d 16 below to download emWin and then modify your local project.
alindvall 0:582739e02e4d 17
alindvall 0:582739e02e4d 18 How to get it
alindvall 0:582739e02e4d 19 -------------
alindvall 0:582739e02e4d 20 The library must be downloaded from the page above and at the time this
alindvall 0:582739e02e4d 21 document was written the latest version was emWin 5.24h with the direct
alindvall 0:582739e02e4d 22 link: http://www.lpcware.com/system/files/NXP_emWin524h_libraries.exe
alindvall 0:582739e02e4d 23
alindvall 0:582739e02e4d 24 Download the executable, run it and have it extract the files to the emwin/
alindvall 0:582739e02e4d 25 folder. After extracting the archive, the emwin/ folder should contain the
alindvall 0:582739e02e4d 26 following:
alindvall 0:582739e02e4d 27
alindvall 0:582739e02e4d 28 emWin_Config\
alindvall 0:582739e02e4d 29 emWin_header\
alindvall 0:582739e02e4d 30 emWin_library\
alindvall 0:582739e02e4d 31 readme.txt
alindvall 0:582739e02e4d 32
alindvall 0:582739e02e4d 33 The the 5.24h version (and possibly other later versions as well) is missing
alindvall 0:582739e02e4d 34 PNG support but the manual (available on the linked page above) has instructions
alindvall 0:582739e02e4d 35 on how to add it. Download www.segger.com/link/emwin_png.zip and extract it
alindvall 0:582739e02e4d 36 into the png/ folder. After extracting the folder should contain one or more
alindvall 0:582739e02e4d 37 version folders. This is what the png/ folder may look like:
alindvall 0:582739e02e4d 38
alindvall 0:582739e02e4d 39 emWin_V5.18/
alindvall 0:582739e02e4d 40 emWin_V5.28/
alindvall 0:582739e02e4d 41
alindvall 0:582739e02e4d 42 Delete the version that you don't need (probably the oldest one).

alindvall 0:582739e02e4d 44 Updating the project
alindvall 0:582739e02e4d 45 --------------------
alindvall 0:582739e02e4d 46 When this project was exported it did not have the correct paths and files
alindvall 0:582739e02e4d 47 needed by emWin (for lisence reasons). This is what you have to do in your
alindvall 0:582739e02e4d 48 IDE to get it to work:
alindvall 0:582739e02e4d 49
alindvall 0:582739e02e4d 50 Keil uVision 4:
alindvall 0:582739e02e4d 51 ==============
alindvall 0:582739e02e4d 52 1) Open the project
alindvall 0:582739e02e4d 53 2) Select the Project->Manage menu
alindvall 0:582739e02e4d 54 3) Add a new Group "emLib"
alindvall 0:582739e02e4d 55 4) Add all DMemWin/png/emWin_V5.28/GUI/PNG/*.c files "emLib" group
alindvall 0:582739e02e4d 56 5) Add DMemWinGUI/emwin/emWin_library/Keil/emWin_M4.lib to the "emLib" group
alindvall 0:582739e02e4d 57 6) Close the dialog
alindvall 0:582739e02e4d 58
alindvall 0:582739e02e4d 59 NXP LPCXpresso IDE:
alindvall 0:582739e02e4d 60 ==================
alindvall 0:582739e02e4d 61 1) Open the workspace
alindvall 0:582739e02e4d 62 2) Import the project from the exported zip file
alindvall 0:582739e02e4d 63 3) Right-click on the DMemWin folder in the Project Explorer and select Refresh...
alindvall 0:582739e02e4d 64
alindvall 0:582739e02e4d 65 Other IDEs:
alindvall 0:582739e02e4d 66 ==========
alindvall 0:582739e02e4d 67 Do the corresponding actions for your IDE but remember to use the correct
alindvall 0:582739e02e4d 68 library file.
alindvall 0:582739e02e4d 69
alindvall 0:582739e02e4d 70 If the IDE doesn't get the paths correct by the exporter then you might have
alindvall 0:582739e02e4d 71 to add the following to the include path:
alindvall 0:582739e02e4d 72
alindvall 0:582739e02e4d 73 DMemWin/emwin/emWin_header/
alindvall 0:582739e02e4d 74
