STM32H750VB and dual buffer (320x480) 16bit TFT

Hi,

I want to know if it's possible to make a 320x480 16Bit LCD as dual buffer, since the internal SRAM of MCU are not continuous!

Is there a trick!

Best Regards

One buffer need 307200 continuous ram , second buffer need 307200 too continuous in any place.

There is a 512KB continuous  ram along some 128K regions, total is 1MB,

So I can only declare one Buffer with this scenario, although my MCU has more RAM!

Is there any trick using MDMA to create a linked list and use dual buffer!

If not, why TouchGFX does not do it for next release!
