  • JPEG API problem

    Hi,

    I am using STM32F429I-Discovery board and STemWin v5.32.

    I am trying to use a JPEG image without converting it to c format. I am supposing that putting the file within the project folder will be enough in order to use the JPEG API.

    The problem comes when, for example, I try to run the 2DGL_DrawJPEG example. When I compile it, I have an error related with the windows.h library and when i attache it to my project the error is that, as the compiler I am using (keil compiler) is not a GNU compiler, I cannot use this library.

    What can I do to run the example?

    Thanks!

  • Hi,

    Some examples are written for the simulation using some windows specific functions. The example you are referring to is one of those.

    In this case you have to exchange all windows function with functions compatible for your device. In this case you would require a filesystem to open the JPEG file.

    Take a look into the example attached. It should show how to read the JPEG from an c-array.

    Regards,
    Sven
