Simple Open Source EtherCAT Slave

SOES (Simple OpenSource EtherCAT Slave Stack) is an opensource slave stack that is very easy to use and provides a small footprint. It is a good alternative to more complex stacks on the market.

This forks adds support for EtherCAT slave HAT with LAN9252 chip (like EasyCAT or EtherC/EtherBerry) for Raspberry PI using the BCM2835 library.

Overview

SOES is an EtherCAT slave stack written in c. Its purpose is to learn and to use. All users are invited to study the source to get an understanding how an EtherCAT slave functions.
