EVE Screen Designer to generate source code

huseyinkozan

Hi,

We have NHD-3.5-320240FT-CSXN-CTP, and want to use it with a Toradex Colibri iMX6 module. A Qt/C++ application will run and control the display.

I tried the designer, but I dont what target platform should I select.

Can we use EVE Screen Designer to generate source code ? Which target platform should we select ?

Thanks

    Hi,

    To achive that we need linux hal files for using spi communication and gpio pins. And also create desginer project with appropriate resolution(for NHD_3_5C_FT813 it is QVGA 320x240). It doesn't matter which device selected, but resolution is important.

    After you saved a project, Designer generate C code of your project under ProjectFolder/Generated. To use project with Qt create a project with Qt Creator and add `ProjectFolder/Generated` folder and sub directories and  `PathtoEveScreenDesigner/Libraries`  folder and sub directories except `ThirdPartyLib`. And add linux hal files to project. Don't forget to add folders with sub directories to include path.

    You need to add some defines your code. To define globally, add them to `.pro` file.

    #It depends on which hal file you want to use, I write hal file for this define
    DEFINES += Linux_PLATFORM

    #These are defines for lcd, different lcd models reuire different defines
    DEFINES += DISPLAY_RESOLUTION_QVGA   
    DEFINES += EVE_GRAPHICS_AVAILABLE
    DEFINES += EVE_DISPLAY_AVAILABLE
    DEFINES += FT813_ENABLE

    There are lot of lower/upper case issues with file names because Designer is windows program and windows is not case sensitive with file names, however Linux is case sensitive. I have fixed it with, try to compile, get error, fix filename and try again.

    An implementation of Linux_Hal and example project can be found here .
