Hello Eblec.1,

Ok, and what did you put for dimensions of your application on TouchGFX Designer ? 240*240 or 320*240 ?

Also did you modify the dimension of your display with STM32CubeIDE ?

Hello, Oskt.

I declared the 320 width, 240 height in stm32cubemx for software-packs / touchGFX / display.

I didn't see any other place to set this.

in touchGFX config / display I see it as W 320 * H 240.

I didn't look for it in the IDE.

thanks. eyal.

Hello Eyal,

Indeed that would be enough. And what is the "Display Interface" configuration you have on STM32CubeMX ? LTDC, FMC ?

hello, Oskt.

I set the display interface to Custom and added the file I have from the screen manufacture : st7789.c & .h .

[Eblec.1]

I made changes to touchGFXHAL.cpp : copyFrameBufferBlockToLCD & flushFrameBuffer functions,

to be compatible to the st7789 I use.

Hello Eyal,

Have you tried to use other animations like screen transitions, fadeAnimation, changing box/screen color etc...

[Eblec.1]

hello, Oskt.

No, I didn't !

Ok, try with that, it will help us to see if it's a bug related to the animations or the screen itself.

Also, we have an article to check the display screen, you can have a look and try the example with changing the screen color.
