Esmacat HarmonicBionics
An Mbed library for an EtherCAT Arduino Shield developed by Esmacat to connect the larger Arduino ecosystem and other MCU boards capable of connecting a shield with an Arduino Uno form factor. EASE can easily turn an MCU board, including the Arduino ecosystem, into a cost-efficient EtherCAT slave subsystem in the larger EtherCAT system. Using EtherCAT communication, EASE can reliably communicate with other base boards through an EtherCAT master.
