Added SPI speed parameter
Dependents: EasyCAT_LAB_simple EasyCAT_LAB
- The default SPI speed has been set to 27MHz, but it can be configured using the last parameter of the constructor.
- This is an optimization for the EasyCAT LAB , a complete educational and experimental EtherCAT® system, composed of one master and two slaves .
