OpenMV Cam M7 dedicated DMA for USB Camera 2.0 operation

Hi all,

I was wondering if someone has made an approach regarding the dedicated USB DMA of the STM32F7 MCU, which would allow direct transfer from the DCMI interface to the USB 2.0 port, so that higher transfer rates (up to 54Mbytes/s as limited by the DCMI interface) would be theoretically achievable.

Thank you in advance,

Youd need USB 2.0 high-speed which requires an external PHY chip. We don’t have this on the camera board so we’re locked at 12 Mbps.
