3.5" LCD (320x480) & MCU Interface

I am trying to use a 320x480 TFT LCD with the STM32F767IIT, FreeRTOS, TouchGFX.

I think that the 450 Kbytes (320xRGBx480) capacity is required, but the RAM capacity of STM32F767IIT seems to be insufficient. .

Any advice on whether to add SDRAM on the STM32F767 or using the STM32H747 (RAM 1 Mbytes) would be better.

Hello,

It really depends on your budget and how much struggle you want to go through.

Obviously the H747 is more powerful, has sufficient RAM, and on top of that we have two Application Templates in the Designer, one for H747-DISCO board and one for H747-EVAL board. This should facilitate the development of your project.

As for the F767, we don't have any Application Template for this but we do have for F769 which should be similar.

And in this case you have to add some SDRAM and make sure it works well with the MCU which can take a bit of time.

For time and ease of development I would definitely use the H747.

Your call 😉
