Looking for the right hardware solution.

Postby phdinfunk » Fri Mar 25, 2016 4:27 pm

Hi, I'm overseeing a project design and we need to handle a lot of SPI connections. Basically, I'm trying to simultaneously address 3 or four 8 CH A/D converters. (Engineer likes these: http://www.mouser.com/ProductDetail/Ana ... 252b8%2fjj). Additionally, I'm going to have about four times as many DACs along with 4 crosspoint switches.

And we're shooting for latency under 10ms or so. :-)

If nothing else, Parallella looks like it can address enough I/O for this. All I was able to find about Epiphany cores is they can each handle I/O independently on interrupts. But I need a pretty short answer on this. From what I said above, does it sound like Parallella is the way to go, or should I be looking at another specific solution?

Thanks

Some of our customers need latency in the 10's of microseconds range, so yes this should be doable. You will need to be proficient in FPGA design to instantiate the SPI logic.
Question is really how many IO pins you need in total. The Embedded version supports up to 48.
