“Use a RaspberryPi master to communicate with 2 EtherCAT Arduino Shield by Esmacat(EASE) on Arduino to control motors using LCD shield input.
n this tutorial, you will learn how to set up and use the EtherCAT Arduino Shield by Esmacat (EASE) Slave device on top of an Arduino subsystem and interface it with an LCD and Motor Shield to enable data transfer between the two slave devices via the EtherCAT master (Raspberry Pi).
First, some general information about Raspberry Pi and the shields is discussed.
After learning to set up the devices, you will learn to implement a practical project involving both the LCD and Motor Shields to control the Motors connected via the buttons on the LCD Shield by exchanging data between the 2 slave devices and the EtherCAT master. The data about the current motor to be controlled and its state (speed/position) is also printed on the terminal of the Pi.
EtherCAT Arduino Shield by Esmacat (EASE):
EASE is an EtherCAT slave that connects to an EtherCAT master (PC/ Laptop/ Dedicated Master devices like the Esmacat Master S and Esmacat Master C. It can be stacked on top of Arduino, Arduino-like boards and Arduino Shields. This shield allows high-speed communication with an industry-standard EtherCAT protocol for high-performance robotic applications.”
