Build an EtherCAT Slave

Dependencies:   EsmacatShield

Quick Build EtherCAT Slave

Esmacat is an easy yet powerful EtherCAT solution for robot mechatronics developed by Harmonic Bionics. It provides a full EtherCAT hardware and software solution for Master and Slave devices which allows developers to set up and run an EtherCAT application within minutes. It also supports Power-over-EtherCAT (POE) technology which allows high-speed communication and logic-power supply over a single Ethernet cable simplifying the cabling and wiring needs of the system significantly.

EtherCAT Arduino Shield by Esmacat (EASE) is a shield which can be used to build a Slave device. It stacks onto Mbed boards with form factor of Arduino UNO. The Mbed Base board communicates with EASE over SPI. EASE communicates with the Master over EtherCAT. Multiple EASE boards can be connected with Ethernet cables in a daisy-chain topology.

+ * @brief   mbed test application - Esmacat Shield(EASE) working together with 
+ *          Base Board with Arduino UNO form factor as EtherCAT slave.
+ *          With the successful execution of this code the LED on EASE should
+ *          blink. It should also estabilish data transfer between the EtherCAT
+ *          Master of Esmacat on the PC.
