EasyCAT LAB - EtherCAT master very simple example

Dependencies:   SOEM

  • This repository contains a very basic example for the EasyCAT LAB , a complete educational and experimental EtherCAT® system, composed of one master and two slaves.

Note

  • This example uses two LAB 2 slaves.

Note

  • In this example, to keep things as simple as possible, only two bytes of data are exchanged between the slaves and the TFT display is not used .
