STM32L476 + RGB interface

[CocoJambo]

Hello, everyone!

I'm developing smartwatch as a project and I'm planning to use a TFT display which has 18RGB interface. I have STM32L476 at my disposal that doesn't have any embedded LTDC module.

Should I change MCU to one that does have LTDC in order to receive/transfer data or I can use some external buffer between MCU and display?

STM32L4R5, STM32L4R7 or STM32L4R9 might be a better choice because they already contain the graphics controller and plenty of memory that you can use as a frame buffer.

The STM32L4R7 and STM32L4R9 even contain the Chrom-GRC (GFXMMU), with which you can save RAM on round displays that would otherwise be used for the corners that do not exist.

Maybe you need define more your LcD, but when realy you plan use RGB18 , then yes this mcu isnt for you.

But 476 have FMC for LCD or SPI.
