DynamicBitmapCreateExternal() for RGB565

[Priyank]

Hi, I am creating a DynamicBitmapCreateExternal() for RGB565, but the image shows up faded. Is there any fix for this? I made sure to set cache for it. I also tried for L8 and it didn't show.

Hello, @GaetanGodart @JohanAstrup   

I've run the same tests under TouchGFX 4.26.0, but I still run into the issue of the image looking grainy/faded. Does stm32cubeIde also need to be updated? I am running that on an older version (1.16.1)

 static uint16_t cacheSize[512];
    Bitmap::setCache(cacheSize, sizeof(cacheSize),1);
    volatile BitmapId bmpId = Bitmap::dynamicBitmapCreateExternal(185, 43,(void*)image_logo, Bitmap::BitmapFormat::RGB565);

Hello @Priyank.

You do not have to update STM32CubeIDE.
Instead, try deleting the ST folder in the Middlewares folder and then regenerate code in TouchGFX Designer.

Best regards,
Johan
