Data transfer between two STM32 devices using FSMC

Hi,

I'm currious if it is possible to share data between two STM32 devices, using the FSMC interface.

Is it possible to configure one device as a Master and the other as a slave and use the FSMC? I would make the slave device act, as it was a SRAM memory, for example.

If not, is there a parallel peripheral to transfer data between two STM32 devices?

Thanks in advance,

Regards,

Not really, it's an outbound interface, and there isn't a way to do a DMA type REQ/ACK protocol externally. Synchronization was also be an issue.

The best way to attack this would be using a dual-port memory or FIFO, or use an FPGA

Maybe the camera interface could be used as a slave, but it's surely not an out-of-the-box solution.

Ok,

Thank you all!
