About this example
This is an example application to demonstrate the ease with which a system, which communicates over EtherCAT, can be build. It measures the RPM of a motor using a proximity sensor.
Following lists the hardware required
- 2 x Mbed boards with Arduino UNO form factor (NUCLEO-F103RB)
- 2 x EASE boards
- 1 x proximity sensor shield (X_NUCLEO_6180XA1)
- 1 x Motor shield (X-NUCLEO-IHM01A1)
- 1 x stepper motor
- 1 x Ethernet POE injector with a 24VDC power supply
- 2 x Ethernet cables
- Keyboard, mouse, and monitor
- PC with Linux/Windows OS installed
- DC power supply for motor
