With DCMI (with DMA) and USART only 1.5FPS, why is the frame rate really low?

Probably because the bandwidth of.the UART is very low?

I set the baudrate to 912600, and the camera output is JPEG, so I don't think USART is too slow.

Hello @Shiina ,
Which camera sensor are you using? Are you encountering the same behavior with RGB?
Please take a look at How to improve DCMI frame rate: An example using a ov5640 camera module may help you to increase the DCMI frame rate.
Thank you.

Depends on image size and efficiency. Frame rate suggests images about 60KB
