Hi,
I am using STM 32H745I disco boards. When I have configured the boards with LTDC interface image has been displayed on 480*272 display.
Now we have removed on board 480*272 display , we have connected external 480*480 display & I have initize the display through SPI.
I want to know wheather is it possible ?
If yes ...then how it needs to be configured ?
Thankyou

The datasheet of the display should tell how to use it. If it doesn't connect over LTDC, you're going to need a different interface to control it compared to the previous display.

so what is the question?
I understand your mean is that 1. you used LTDC to connect 480*272 display before; 2. now you want to use SPI to connect 480*480 display?
if the display support the SPI interface, it is possible to apply this display on board, but the image transfer speed will be lower than LTDC interface.
