Is the STM32F46G-Discovery (v2.0.0) 24 bit supported in Stm32CubeIDE?

I recently created a project for the Stm32F746G-Discovery kit in TouchGFX 4.12.3 and chose version 2.0.0. I was only able to select 24 bit color depth.

When creating a new project in STM32CubeIDE 1.1.0, I was only presented with one option for the STM32F46G-Discovery kit, so I chose it. I see that it is only 16 bit color depth as seen in the BoardConfiguration.cpp file as well as with in the Stm32CubeMX > Middleware >TouchGFX section.

Am I missing something, is there a way to set this up?

Hi Scott,

This is because Application templates through the designer are made to showcase various bit depths. When you configure things from scratch through CubeIDE/MX you're creating a SPECIFIC hardware configuration (16,24, etc).

Thanks for your reply Martin.

I am still a bit new at CubeMX, so I am a bit unsure where it needs to be setup.

I assumed it was the LTDC Display Type, but when changing that, the TouchGFX Color Frame Buffer Depth did not change.

However, when I changed the LTDC > Layer Settings > Pixel Parameters, it did effect the TouchGFX Color Frame Buffer Depth. I show it below for other people's reference:

Change reflected in TouchGFX Color Frame Buffer Depth:

I also found that this does automatically alter the TouchGFX BoardConfiguration.cpp file as well (which is very helpful). 

And, since this relates more to STM32CubeMX, I added this thread to that topic as well.
