I have integrated ILI9341 SPI display to Touch GFX. Frame Buffer Pixel Format is - RGB565 and getting the output. But when I change Frame Buffer Pixel Format from RGB565 to GRAY4 not getting the output.
(Actually ILI9341 Supports RGB565). Is this possible to print GRAY4 images on RGB565 ILI9341 display?
Frame Buffer Pixel Format : RGB565
Frame Buffer Pixel Format : GRAY4

Hello @Vins ,
What does "not getting the output" mean for you ?
Do you have corrupted frames or the project is simply not compiling ?
Thanks,

@Yoann KLEIN Project is compiling but not showing any images from the Touch GFX on ILI9341 display.

What happens when you run on target ?
Can you share screenshots or picture of your display?

@Yoann KLEIN
It shows only 3 vertical lines.

And which MCU are you using ?

TouchGFX dont mangle framebuffer format to other format for hw LCD. You need rewrite your custom code for partial buffer sending .
