AB&T / SPI_TFT_ILI9341

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 .
