Hi,

I'm trying to interface 400*400 camera with 800*480 lcd display.

i have done changes for lcd as per the datasheet but still im not getting output as expected.

before i have already interfaced 400*400 camera with 480*272 lcd display it's working fine, but now I'm trying to interface with 800*480 lcd.

Hello @Bhanu,

The resolution of LTDC and SDRAM are related. You can refer to this post and check if the 128Mbit SDRAM is able to support 800x480 resolution.

I suggest you take a look at this AN4861 Application note LCD-TFT display controller (LTDC) on STM32 MCUs and STM32F7-LTDC and precisely Two programmable LTDC layers section.

I hope this helps!

Thank you.

Kaouthar.
