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.
