Hi.
I want to acquire data from a 5M pixel image sensor (for example OV5640) with YCbCr4:2:2, 8bit using DCMI.
(I want to process the image data, so I need to transfer it to memory using DMA)
However, AN5020 and RM0481 (Rev1) mention a maximum of 2048*2048, so I'm about to give up.
This description seems to have disappeared in the latest RM0481(Rev2),, but I would like to know if the above description is accurate and if there is a limit on the input size.
If you have any experience using it without any problems, I would appreciate any information.

Hello @BLUE and welcome to the Community :),
The DCMI has a very wide image definition (14-bit so 16k x 16k). So, the maximum input size is 16384x16384.
Please make sure that you don't have a bandwidth limitation to drain through the DMA.
Thank you.
