Changing on Display

[Bea_12]

Hello everyone,

I am currently working with the STM32F746 and have implemented a brightness controller. I can control the regulator via code (CubeIDE) and assign a value. However, I don't understand how to make the display actually adjust its brightness accordingly. I have already searched the internet but haven't found anything that helped me.

Does anyone have experience with this or know which approach I should take? Do I need to control the backlight separately, and if so, how can I do this? Any help or pointers would be greatly appreciated!

What does the datasheet for the display say?

You haven't said what display you're using.

Are you using TouchGFX?
