Is it possible to use the LTDC's L8 mode with TouchGFX?

[sdk77]

Hi,

I'm new here and I'm starting to develop an application on STM32H750 with TouchGFX. I've read about the STM32 LTDC's L8 (8-bit luminance or CLUT) mode. This would give a palette of 256 colors which is more than enough, and use very little memory. However it seems TouchGFX only supports framebuffers of 24bpp, is this correct? Or is it possible to let TouchGFX use an 8bpp framebuffer?

Best Regards,

Sjef

Hi @sdk77​,

Funny you should ask, 8 bpp framebuffers will be supported in the upcoming version of TouchGFX. Aside from that, it is not entirely correct that TouchGFX only supports 24bpp: 1 (Regular or RLE), 2, 4, 8, 16, 24.

Hope that helps.
