Color corruption of text in TouchGFX 4.18.1

I created my project in TouchGfx 4.15.0. Currently I'm using TouchGfx 4.18.1. After flashing/debugging ; color of the text which I've given in TouchGfx is getting corrupted. For ex : If I set red(235 ,64 ,61) color to some text, after debugging it becomes a color close to blue. But if the text color is white, it's not getting corrupted. Someone please provide a solution for this matter.

#define ConvertTextColor(RED, GREEN, BLUE) (uint32_t)( ( (RED << 8 ) & 0xF800) + ( (GREEN << 3) & 0x07E0) + ( (BLUE >> 3) & 0x003F) )

Add this macro in Color.hpp

Then call this macro whereever you want. For ex :

Text.setColor(TextColourConvert(Red, Green, Blue) );

Hi,

What MCU are you working with ? Are you working with a custom project or from one of the TBS avaialble in TouchGFX Designer ?

I would suggest to regenerate code from STM32CubeMX to make sure to update the Firmware package (opening your project in STM32CubeMX and migrate to the latest version).

Hello,

I have same issue. I'm using custom board with STM32F767 mcu, display color depth 16 bit, L8 image formats and IDE Keil uVision5. Colors in the pictures are ok. Problem is with colors got by function getColorFromRGB(r, g, b). For example color (32, 60, 82) was changed to (57, 137, 131) (these values were taken from attached "frame buffer screenshots").

Have you tried regenerating code from STM32CubeMX as well ?

No I haven't. My project is multitarget and regenerating makes troubles.
