  10. * DESCRIPTION
  11. * The EthernetGateway sends data received from sensors to the ethernet link.
  12. * The gateway also accepts input on ethernet interface, which is then sent out to the radio network.
  13. *
  14. * The GW code is designed for Arduino 328p / 16MHz.  ATmega168 does not have enough memory to run this program.
  15. *
  16. * COMPILING
  17. * You must make sure to disable DEBUG in Sensor.h before compiling this sketch. Othervise the sketch won't fit in program space when downloading.
  18. * For UIPEthernet(ENC28J60) usage: Note that I had to disable UDP and DHCP support in uipethernet-conf.h to reduce space. (which meas you ave to choose a static IP)
  19. * For WizNET usage: Do *not* install the provided UIPEthernet-library. Remove UIPEthernet-include below and uncomment the Ethernet.h.
  20. *
  21. * VERA CONFIGURATION:
  22. * Enter "ip-number:port" in the ip-field of the Arduino GW device. This will temporarily override any serial configuration for the Vera plugin.
  23. * E.g. If you want to use the defualt values in this sketch enter: 192.168.178.66:5003
  24. *
  25. * LED purposes:
  26. * - RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
  27. * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
  28. * - ERR (red) - fast blink on error during transmission error or recieve crc error
  29. *
  30. *  ----------- Connection guide ---------------------------------------------------------------------------
  31. *  13  Radio & Ethernet SPI SCK
  32. *  12  Radio & Ethernet SPI MISO (SO)
  33. *  11  Radio & Ethernet SPI MOSI (SI)
  34. *  10  Ethernet SPI Slave Select (CS)    Pin 10, the SS pin, must be an o/p to put SPI in master mode
  35. *  9   Radio TX LED using on board LED   (optional)  +5V -> LED -> 270-330 Ohm resistor -> pin 9.
  36. *  8   Radio RX LED                      (optional)  +5V -> LED -> 270-330 Ohm resistor -> pin 8.
  37. *  7   Radio error LED                   (optional)  +5V -> LED -> 270-330 Ohm resistor -> pin 7.
  38. *  6   Radio SPI Slave Select
  39. *  5   Radio Chip Enable
  40. *  3   Inclusion mode button             (optional), 10K pull down to GND, button to VCC)
  41. *  2   Radio IRQ pin                     (optional), W5100 Int, if linked to pin 2)
  42. * -----------------------------------------------------------------------------------------------------------
  43. * Powering: both NRF24l01 radio and Ethernet(ENC28J60) uses 3.3V
