Hi, everyone !

I have a question about  videnc_copy.c

In the file, we can see that:

When we want to copy the data, we have two choices. One is using the DMA----ACPY3_start; another is using the function "memcpy".

Which one is chosen to use depends on "USE_ACPY3".

So what is the value of "USE_ACPY3" ??

And how to use it ??

Thank you !!
