Touchgfx color inversion

KM L.1 · ‎2021-01-10

We are working on the TouchGFX with STM32H7 controller , able to display the images but colors are getting inverted on the LCD. TouchGFX and LTDC configuration looks fine. So what may be the issue.

For Black <--> White

Blue <--> Yellow

Red <--> Blue

Green <--> Magenta

Thank You

Hi,

How did you configure your display ? Before enabling TouchGFX were the colors fine ? You can have a look at the board bring up articles in the online documentation to see how to check and test the display colors.

I believe you are working on a custom board, but you can have a look athe how the ST dev kits are configured by created a project from TouchGFX designer and selecting an application template for a ST kit using an H7 mcus.

Before enabling the TouchGFX we have not looked into the colors..

Yes we are working on a custom board.

Please look into my touchgfx configuration i have attached.

cant really help you without a datasheet. But Like I said, you should disable TouchGFX for now and try to test the display by itself to check the colors.
