Arduino uno + ethernet shield + iPhone + iOSC(OSC Application)

Arduino uno + ethernet shield + iPhone + iOSC(OSC Application)

A LCD didn’t work when I was coding like below.

LiquidCrystal lcd(12, 11, 10, 5, 4, 3, 2);

Take care about a LCD connection port.

I referred to UDPSendReceiveString, Arduino examples (Ethernet).

/*
  UDPSendReceive.pde:

#include          // needed for Arduino versions later than 0018
#include 
#include          // UDP library from: bjoern@cs.stanford.edu 12/30/2008
#include

// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network:
byte mac[]	= { 0xAA, 0xBB, 0xCC, 0xDD, 0xEE, 0xFF };
byte ip[]	= { 192 , 168 , 1 , 1 } ;  //

unsigned int localPort = 10000;      // local port to listen on

// the next two variables are set when a packet is received
byte remoteIp[4];        // holds received packet's originating IP
unsigned int remotePort; // holds received packet's originating port

// buffers for receiving and sending data
char packetBuffer[UDP_TX_PACKET_MAX_SIZE]; //buffer to hold incoming packet,
char  ReplyBuffer[] = "acknowledged";       // a string to send back
LiquidCrystal lcd(8, 7, 6, 5, 4, 3, 2);

void setup() {
  // start the Ethernet and UDP:
  Ethernet.begin(mac,ip);
  Udp.begin(localPort);

  lcd.begin(16,2);
  lcd.clear();
  lcd.setCursor(0, 0);

  Serial.begin(9600);
}

void loop() {
  // if there's data available, read a packet
  int packetSize = Udp.available(); // note that this includes the UDP header
  if(packetSize)
  {
    packetSize = packetSize - 8;      // subtract the 8 byte header
    Serial.print("Received packet of size ");
    Serial.println(packetSize);

    // read the packet into packetBufffer and get the senders IP addr and port number
    Udp.readPacket(packetBuffer,UDP_TX_PACKET_MAX_SIZE, remoteIp, remotePort);
    char* c = packetBuffer;
    if( strcmp(c, "/osc/button1") == 0 ){
      lcd.setCursor(0,0);
      lcd.print("button 1 pushed");
    }
    if ( strcmp(c, "/osc/button2") == 0 ){
      lcd.setCursor(0,0);
      lcd.print("button 2 pushed");
    }
    Udp.sendPacket( ReplyBuffer, remoteIp, remotePort);
  }
  delay(500);
}
