EasyCAT LAB - EtherCAT master legacy example
Dependencies: SOEM SPI_STMPE610 SPI_TFT_ILI9341 TFT_fonts
The EasyCAT LAB is a complete educational and experimental EtherCAT® system, composed of one master and two slaves .
- It 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.
- This repository contains a demo software for the EtherCAT® master, that runs on the Nucleo STM32F767ZI board.
- 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.
