Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Has anyone tried to get to maximites (or variants of) to communicate with each other via SPI?

thanks Don,

I have seen that but RS232 is just a bit slow I was wanting higher speed comms as i have an idea that requires faster communications.
fyi i am experimenting with using one unit as normal with a second as a graphics processor.

You can also use RS485 with a UART, can be as fast as SPI and good for long distances.

Are the two processors on the same PCB?
