- This repository contains the SOEM (Simple Open EtherCAT® Master) library by rt-labs, that has been ported in the
ecosystem by AB&T Tecnologie Informatiche.
- It has been developed for the EasyCAT LAB , a complete educational and experimental EtherCAT® system, composed of one master and two slaves .
- The EasyCAT LAB is provided as a kit by AB&T Tecnologie Informatiche, to allow everybody to have an educational EtherCAT® system up and running in a matter of minutes.
Warning
- Currently only the Nucleo STM32F767ZI board is supported.
