Dear every body,

I are using LCD TFT 7 inch 800x480  https://www.buydisplay.com/default/7-tft-lcd-touch-screen-display-module-800x480-for-mp4-gps-tablet-pc  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!
