    • Hi,

      emWin doesn't require an OS, so the code you referred to should work under these circumstances.

      Best regards,

      Florian
      Please read the forum rules before posting.

      Keep in mind, this is *not* a support forum.

    • Florian,

      What I meant to say was the referred link has usage of code that are used for windows. Since I am not using any OS, I am not able to use some features so I modified it to fit my needs but it still doesn't seem to work. I have attached the code I am working on, could you please take a look at it and let me know what I am doing wrong?

      Best regards,
      BMD

      Display All

    • Hi,

      I was able to make the modifications but I am not able to set the index to display different icons. Could you please see the code and tell me how to do that so I am able to display all the Icons as required?

    • Florian/Sven,

      Could you please help me understand how to display different images assigned to different icons from external memory?? So far, I can only see same image on all the icons. I couldn't find anything on the forum regarding this as well. Any hint will be greatly appreciated.


      Thanks and regards,
      BMD

    • Hi,

      I can't tell what is wrong with your code, my guess is the file handles point all to the same image, thus all icons are the same.

      Best regards,

      Florian
