问题
I am currently making a system using digital camera. I succeeded to make it with dcmi external sync, but what I need to do is do the same thing with dcmi embedded sync(hardware sync) as known as BT.656.
How should I set Frame Start Code, Frame End Code, Line End Code and Line Start Code in Parameter setting in the DCMI Configuration? Or is it something that I don't need to modify?
The configuration window is shown below:

you could check my other post about DCMI configuration for STM32 lineup for hardware sync:
How to configure DCMI peripheral on STM32H7
that part about embedded sync and start\end frame codes:
if you are going to use hardware sync you don't need them, in other case
