This video shows how an image is transfered from a PC tool to a display on a STM32H7. The new thing about it is that the CANopen FD protocol is used. Transferring images might not be the primary use case but it is good to show. In fact CANopen FD using the faster CAN FD protocol enables transfer rate up to 10 times higher compared to classic CANopen and this is in particular useful for firmware uploads. #emtas provides a #CANopen FD stack for the STM32H7 and a complete #CANopen FD toolchain.
