[TouchGFX] New TFT on 32F429IDISCOVERY board

[SKokk.1]

Hello,

I managed to connect several displays on a custom PCB (similar to 32F429IDISCOVERY) using several drivers (ILI9344,ILI9488 etc) and running the TouchGFX library.

Now, I have a problem with a new one. It supports RGB directly but has no DE (data enable) signal.

Should I let the PB10 (= LCD_DE) pin from MCU floating? It confuses me that display has no DE pin (on some displays also called EN).

P.S I am attaching the datasheet

On one of my old projects where I used to drive this TFT with SSD1963 driver, I just noticed that LDEN pin was left floating and display was working without issues. So I am going to let the LCD_DE output pin on STM32F4 floating too.

Hi,

I have edited your post to add another topic so that more people can see this. This is not really TouchGFX related, so I'm hoping that someone with more knowledge on this than me might help you 😅.
