More Code

So the code finally reached a tipping it's time to package the code up into a library. I'm calling it HomeNet because it describes its perfectly it's a new home net work and amazingly enough, there isn't anything going by the name yet.

Compared to the long mess of code posted before, Moving most of the code to a library really simplified things:

#include <ports.h>
#include <rf12.h>
#include <homenet.h>

HomeNet stack(0x04);//start stack with a node id
MilliTimer sendTimer;

void setup() {
  // put your setup code here, to run once:
  stack.init();

}

void loop() {
  // put your main code here, to run repeatedly: 
  stack.receive();
  if (sendTimer.poll(2000)){
    PayloadBuffer buffer;
    buffer.print(123,DEC);
    stack.addUdpPacket(0, 255, 2, CMD_BYTE, buffer.payload());
  }
  stack.process();
}

and the processing sketch using the library

import processing.serial.*;
import xmlrpclib.*;
import org.apache.commons.codec.binary.Base64; //part of the xmlrpclib

XmlrpcClient homeNetXmlrpcClient = new XmlrpcClient("http://matthew.sgcs.usf.edu/mcdportal/public/xmlrpc.php?api_key=dfgdfgdgdgd");
XmlrpcServer homeNetXmlrpcServer = new XmlrpcServer(8081);



final int  NODE_ID = 255;
final int PACKET_TIMEOUT = 150;
PacketStack stack = new PacketStack(NODE_ID);

Serial myPort;  // The serial port


XMLElement xmlConfig;



XMLElement commands[];
XMLElement devices[];

String findXMLid(XMLElement[] xml , int value, String rAttribute){
  String rValue = ""; 
  for(int a = 0; aif(unhex(commands[a].getAttribute("id")) == value){
      return commands[a].getAttribute(rAttribute);
    }
  }
  return rValue;
} 


void setup() {
  size(600, 400);  // Stage size
  //noStroke();      // No border on the next thing drawn
  homeNetXmlrpcServer.add("testserver", this); //setup server
  println("HomeNet XML-RPC Server started at " + homeNetXmlrpcServer.ip()+":8081/RPC2"); // Note that /RPC2 is hard-coded to URI in the Apache Library.
  
  textFont(createFont("Consolas", 14));
  //fixedFont);
  
  xmlConfig = new XMLElement(this, "config.txt");
  devices = xmlConfig.getChildren("devices/device");
  commands = xmlConfig.getChildren("commands/command");
  
  //load the above as hash table from my sevrer.
  
  // Print a list of the serial ports, for debugging purposes:
  //println(Serial.list());
  
  String portName = Serial.list()[1];
  myPort = new Serial(this, portName, 115200);
}

boolean arduinoBoot = false;
int count = 0;
long sendTimer;
void draw() {
  
  if(arduinoBoot == false){
    delay(2500);
    sendTimer = millis();
    arduinoBoot = true;;
  }
  
  if((millis() - sendTimer) > 2000){
    //DataPacket packet = build_udp_packet(NODE_ID,0,3,2,CMD_STRING,str_to_payload("Hello "+count));
    //packet.status = STATUS_READY;
    sendTimer=millis();
    count++;
  }

  stack.process();
    
  stack.tempSerialCheck(myPort); //this is temp until I add support for multiple serial ports, and pass a list of ports to the packetStack
}
void packetEvent(DataPacket packet){
  packet.status = STATUS_CLEAR;
  Hashtable send = new Hashtable();
  String packetBase64 = new String(Base64.encodeBase64(packet.payload));
  send.put("received",packet.received);
  send.put("packet", packetBase64);
  println("Server Reply: "+homeNetXmlrpcClient.execute("HomeNet.addPacket", send));
}  

void serialEvent(Serial port) {
  stack.buildSerialPacket(port);
}

Much easier to use now!
