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.

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.
