Dear every body,

I are using LCD TFT 7 inch 800x480  in our design with STM32F746BTG6 processor working at  200 MHz frequency.

The data is loaded from SDRAM  to LTDC (STM32F7 LCD Controller) using DMA2D and FMC interface (Flexible Memory Controller – Working at 200/2 MHz).

- SDRAM which i'm using:

MT48LC16M16A2 – 4 Meg x 16 x 4 banks

- IDE: MDK Version 5 - Keil

- Library: HAL. 

I have some question to ask you:

How do I enable the frame interrupt ?

How do I disable the SDRAM auto refresh function ?

Please support me.

Thank you!
