MAX1284 Multiple TX to emoncms
------------------------------
For the MAX1284 Internet Gateway http://max1284.homelabs.org.uk/
Receives data from multiple TinyTX sensors and/or emonTX and uploads to an emoncms server
Optional feature to gets NTP time every so often and transmit for remote GLCD displays

Based on emonbase multiple emontx example for ethershield by Trystan Lea and Glyn Hudson at OpenEnergyMonitor.org


Requires modification to Jeelib library as follows or use version here: https://github.com/nathanchantrell/jeelib


In RF12.cpp

Add new pin definitions for the MAX1284:


  #elif defined(__AVR_ATmega1284P__)

  #define RFM_IRQ     2     // The PIN the IRQ is on
  #define RFM_IRQ_NO  2     // The IRQ number
  #define SS_DDR      DDRC
  #define SS_PORT     PORTC
  #define SS_BIT      5

  #define SPI_SS      4     // PB4, pin 5
  #define SPI_MOSI    5     // PB5, pin 6
  #define SPI_MISO    6     // PB6, pin 7
  #define SPI_SCK     7     // PB7, pin 8



AND CHANGE:

  #else
      if ((nodeid & NODE_ID) != 0)
          attachInterrupt(0, rf12_interrupt, LOW);
      else
          detachInterrupt(0);
  #endif

TO:

  #else
      #if RFM_IRQ_NO  // If IRQ number is defined use that, if not use IRQ0
      if ((nodeid & NODE_ID) != 0)
          attachInterrupt(RFM_IRQ_NO, rf12_interrupt, LOW);
      else
          detachInterrupt(RFM_IRQ_NO);
      #else
      if ((nodeid & NODE_ID) != 0)
          attachInterrupt(0, rf12_interrupt, LOW);
      else
          detachInterrupt(0);
      #endif
  #endif
