IXM collector

See here information on the Illuminato X Machina (IXM)

The collector is a small utility which can be included in your sketches to allow printing directly back to a central observer (probably your laptop) through a virtual face. The following example sketch (included as sketch.pde in this repository) demonstrates it's usage.

#include "collector.h"          // include the collector
int cface;                      // the virtual face assigned to the
                                //   collector
int ledPin = 13;                // LED connected to digital pin 13
int wait;                       // a variable for the delay time

void setup() {
  cface = collector_init();     // initialize the collector and assign
                                //   the virtual face
}

void loop() {
  wait = random(2000);          // set wait to a random number
  delay(wait);                  // wait for the assigned time
  digitalWrite(ledPin, LOW);    // sets the LED on
  // print to the collector face and the result will be automatically
  //   routed to your laptop
  facePrintf(cface, "waited %d miliseconds\n", wait);   
  delay(500);                   // wait for the assigned time 
  digitalWrite(ledPin, HIGH);   // sets the LED off
}

Once this sketch has burned to your boards, you send a c-packet (c2 in the example below) telling your boards that you will be the collector. Each c-packet should contain a number – boards keep track of the highest c-number they have received and will ignore any c-packets with lower numbers. Once the boards receive this c-packet their collector face will be connected to the sender of the c-packet. this is should in the following output of the above example sketch.pde.
