Unable to output color sensor values on Nextion Screen

[gbri29]

I am using Easy Nextion Library to output variables of a color sensor connected to an Arduino UNO. However, when I go to debug on the NextionEditor software this does not even connect to the microcontroller. Although this is working and on. I have put the color sensor code inside the trigger function and I am pasting printh 23 02 54 01 in the bottom to trigger the function. Still nothing happens. The color sensor works by itself but not once it is combined.

#include "EasyNextionLibrary.h" // Include EasyNextionLibrary
EasyNex myObject(Serial); // Create an object of EasyNex class with the name "myNex"
// Set as parameter the Serial you are going to use
#include <SoftwareSerial.h>
SoftwareSerial mySerial(0,1); // RX, TX pins in your aduino

// Define color sensor pins
const int S0 = 2;
const int S1 = 3;
const int S2 = 4;
const int S3 = 5;
const int sensorOut = 6;

// Connections to A4988
const int dirPin = 7; // Direction
const int stepPin = 8; // Step

// Calibration Values from Calibration Sketch
int redMin = 148; // Red minimum value
int redMax = 178; // Red maximum value
int greenMin = 143; // Green minimum value
int greenMax = 167; // Green maximum value
int blueMin = 139; // Blue minimum value
int blueMax = 155; // Blue maximum value

// Motor step angle: 18 -- Motor steps per rotation: 20 (360/18)
const int STEPS_PER_REV = 20; //100 goes 3/8in = 0.375in, so every 1 moves 0.00375in (or 0.9525mm). 8mm/0.09525 = 83.989 ~ 84 (8mm is distance between center of one square on the strip to another square)

// Variables for Color Pulse Width Measurements
int redPW = 0;
int greenPW = 0;
int bluePW = 0;

// Variables for final Color values
int redValue;
int greenValue;
int blueValue;
int redVal;
int greenVal;
int blueVal;

//Variables for averages and totals of readings
int avgRed;
int avgGreen;
int avgBlue;

// Results
int pH = 0;
int Leukocytes = 0;
int Nitrite = 0;
#include <stdbool.h>
// For Nextion Display
//#include
String pHString = String(pH,2);
String LeukocytesString = String(Leukocytes,2);
String NitriteString = String(Nitrite,2);

int x = myObject.readNumber("dp"); // Store to x the ID of the current Loaded page

bool rgb_test(int minr, int maxr, int ming, int maxg, int minb, int maxb, int r, int g, int b) {
return r <= maxr && r >= minr && g <= maxg && g >= ming && b <= maxb && b >= minb;
}

}

void setup() {
myObject.begin(9600); // Begin the object with a baud rate of 9600

}
void loop(){
myObject.NextionListen(); // This function must be called repeatedly to response touch events
}
void trigger01(){

void begin(){
myObject.begin(115200); // for baud rate 115200
}
void writeStr(){
if(myObject.currentPageId != myObject.lastCurrentPageId){
if(myObject.currentPageId == 0){
// [send the data to refresh the page0]
}else if(myObject.currentPageId == 2){
myObject.writeStr("page page0"); // Sending this command to change the page we are on Nextion using pageName
myObject.writeStr("page 2"); // Sending this command to change the page we are on Nextion using pageId

    myObject.writeStr("t1.txt", pHString);
    myObject.writeStr("t2.txt", "\\r" + LeukocytesString);
    myObject.writeStr("t3.txt+", "\\r" + NitriteString);
/* By writing \\r, you send Nextion the change line character " \r "
 * The second \ is required, in order to print the \ as character
