pub async fn capture(&mut self, buffer: &mut [u32]) -> Result<(), Error>

This method starts the capture and finishes when both the dma transfer and DCMI finish the frame transfer. The implication is that the input buffer size must be exactly the size of the captured frame.

Note that when buffer.len() > 0xffff the capture future requires some real-time guarantees to be upheld (must be polled fast enough so the buffers get switched before data is overwritten). It is therefore recommended that it is run on higher priority executor.
