After I update TouchGFX to 4.26 version, Display color changed

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.

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.

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,

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.
