EasyCAT LAB - EtherCAT master simple example

Dependencies: SOEM SPI_TFT_ILI9341 TFT_fonts

This repository contains a simple example 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.

It uses the SOEM (Simple Open EtherCAT® Master) library by rt-labs, that has been ported in the ecosystem by AB&T Tecnologie Informatiche.

The slaves are based on the EasyCAT SHIELD and the Arduino UNO.

Note

This example uses two LAB 2 slaves.

Note

In this example only two bytes of data are exchanged between the slaves and are also visualized on the TFT display.
