Problem: UDP Wraped with If Statement

Projects Programming
20

Gentlemen,

I removed the muxShield (the multiplexer) and wrote a similar code with only 2 sensors and I used digital pins 5 and 6. This works just fine. See the code below.

I think the pin conflict is what's causing the problem. Look at the code below. Can you please suggest a solution?

#include <SPI.h>
#include <Ethernet.h>
#include <EthernetUdp.h>

const int pinNumber1=5;
const int pinNumber2=6;

byte dataBuff[2];

int sensorVal1;
int sensorVal2;

byte arduinoMac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress arduinoIP(192, 168, 1, 192);  // desired IP for Arduino
unsigned int arduinoPort = 8888;        // port of Arduino

IPAddress receiverIP(192, 168, 1, 135); // IP of udp packets receiver
unsigned int receiverPort = 6000;       // port to listen on my PC

EthernetUDP Udp;

void setup() {
  Ethernet.begin(arduinoMac,arduinoIP);
  Udp.begin(arduinoPort);

  
  pinMode(pinNumber1, INPUT);
  pinMode(pinNumber2, INPUT);
  
  Serial.begin(9600);
}

void loop(){
  
   int dataChanged=readData();
   if(dataChanged){
     ProcessData();
   }
   
}


int readData() {
  int dataChanged=0;
  
      sensorVal1=digitalRead(pinNumber1);
      sensorVal2=digitalRead(pinNumber2);

  
  if (sensorVal1 != 1 || sensorVal2 != 1) {
    dataChanged=1;
    } 
  return dataChanged;
}

void ProcessData() {
  Serial.println("Process");
  
    dataBuff[0] = (char) sensorVal1;
    dataBuff[1] = (char) sensorVal2;

  Udp.beginPacket(receiverIP, receiverPort);
  Serial.println("UPD Recieved");
  Udp.write(dataBuff, sizeof(dataBuff));
  Serial.println("UPD Written");
  Udp.endPacket();
  Serial.println("UDP Ended");
}
