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, A.

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 FPGA2013-01-28 12:12 AM
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! Regards A. Paiva
