    Parallel read on Edison gpios possible?


      Hello all!


      I'm looking for information about a possibility doing parallel reading of a range of gpios on the Edison Compute Module. I have to design a PCB with several Edison module in parallel and I want to test if this is possible to perform such operation and compare its bandwidth versus the standard SPI communication. I already have used the mraa lib to interface Edison with an MCP2515 trough SPI, but I didn't find any information about "how to setup a pseudo parallel port gpios-based" within this library. Maybe system calls can achieve that.


      In advance, thanks for any answers/tips/suggestions!
