EtherCAT + Nerves

Thanks for the answer, you give me a good path to follow !!! :).

If you do not mind to tell us, did you used the nerves official supported hardware or another one?
I’m asking it because I’m planning to use a Rpi3 and I want to know if it’s worth to looking at igh-ethercat or directly to the Arcontis, or which were your performance limitations that igh-ethercat doesn’t accomplished?
Also I want to ask:
In your opinion, which package is more friendly to use (or to make an elixir wrapper)?

Thanks in advance…
