After I update TouchGFX to 4.26 version, Display color changed

[MJKIM]

I'm currently using Touchgfx after updating from version 4.25 to 4.26.

When I build and run the code generated by Touchgfx 4.26, Display color doesn't match the design in Touchgfx 4.26.

But When I do the same thing through Touchgfx 4.25, Display color matched very well.

Hello @MJKIM ,

Could you give more info about your application?

• Which STM32 MCU are you using?
• Do you work on a custom board or does this issue happened on a ST discovery board?
• If this is your own custom board, which type of screen is this?
• What's your framebuffer color format?
• Does this issue happen on image assets/shapes/text elements?
• Is there any transparency used?
• Do you use image compression?

BR,

Hey, was this ever solved?

I've run into the same problem and even with GIT Control, and reverting to a previous version I knew definitely worked. Something with the IDE or/and TouchGFX is making the colours change after updating version.

Resorting back to a previous version of TouchGFX 4.25 and colours are still in a different state

Kind regards,

Andrew

Have you tried deleting all generated code and generating it again?

Is that generated code both under TouchGFX and under STM32CubeIDE debug and application?

Thank you

I meant TouchGFX generated code. But you can also try STM32CubeMX code. Middlewares might not be updated.

Debug folder has no generated code, only build artifacts.

Sorry I am late. I solved it already.. 

But I forgot how to solve..Maybe I changed the RGB color setting in CubeMX.

I think It was a collision between touchgfx old version and touchgfx new version.

I saw new version's updated list on touchgfx official website.

Hey,

would you be able to find out which RGB color setting you changed?

Kind regards,

Is default Touchgfx setting "RGB565"?

you can check it  in CubeMX.
