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.
