Pysoes? Simple EtherCAT Slave Stack wrapper #115

Hi, Sorry if this is not the proper place to ask, but do you think it would be feasible to create a similar wrapper for the SOES (Simple Open EtherCAT Slave Stack) library? I am looking for a way to create soft EtherCAT Slaves for testing purposes. I also wonder if you did the wrapper for the SOEM totally by hand or used a tool to make part of it. Thanks in advance!

Hi, sorry for the late response, it is holyday time. I remember there was a similar question in issue #31, maybe my answer there is already satisfying enough? Apart from that, creating a basic SOES C-based firmware for the Infineon XMC4300 Relax EtherCAT® Kit is not that difficult. I did this myself based on an example I found inside the SOES project.

No problem, and thanks for the answer! Very interesting links. Our idea is to create a basic emulated Ethercat slave. That said, there should not be special hardware involved, just a normal PC, doing soft-emulation. We just want the slave to interact with the telegrams. I understand that it may be a problem if real-time is required, but maybe could work for no-real-time applications? Another concern is if it would be possible to emulate several slaves in the same PC? Regarding the wrapper, I have some experience working with Cython. I have checked your code here and I can understand it quite well. Did you develop it completely manually or you used a tool to generate it? Thanks again!
