error to convert int to char on Arduino

Projects Programming

Hello everyone, I would like to display a variable on my TFT LCD screen

During the uploading, the software indicates an error related to the conversion from INT to CHAR.

I've join my code hoping to get your help to tell me where the problem is and help me solve it thank's you in advance.

cordially

#include <UTFT.h>

//désignation des polices

extern uint8_t SmallFont[];
extern uint8_t BigFont[];
extern uint8_t SevenSegNumFont[];

UTFT myGLCD(CTE32HR,38,39,40,41);

float range_max = 12.8 ;
float range_min = 12 ;
float Read_Volts = 12.5 ;

// Déclarations des variable
int Laser = A10;
int Detector = A11;
int coup;
int JP;
int kmh;
int tour;
int tt;
int vall;

void setup()
{
myGLCD.InitLCD();
myGLCD.clrScr();
Serial.begin(19200); // Déclacration du protocole de communication avec les composants
pinMode(Laser, OUTPUT); // Dire que le laser est un émetteur (TX)
pinMode(Detector, INPUT); // Dire que le Détecteur est un récepteur (RX)
coup = 0; // initialisation de la variable coup
kmh = 0; // initialisation de la variable kmh
}

void loop()
{

digitalWrite(Laser, HIGH); // allumer le laser
boolean val = digitalRead(Detector); // Demmander de lire l'état du récepteur laser

for (int vall = 0; vall <= 3436; vall++ ) { //dire que "vall" et = a 0, pour toute valeur "vall" <= 0, "vall" = vall+1
vall++;

if (val == 1 && JP == 0) { // Si la variable "val"= à 1 et que la variable JP = 0, alors coup = coup+1 et JP = 1
coup++;
JP = 1;

}

else {
if (val == 0 && JP == 1) { // Si la variable "val"= à 0 et que la variable JP = 1, alors coup = coup+1 et JP = 0
coup++;
JP = 0;

}
}
if (coup == 12) { // Si la variable coup = 12, alors la variable tour = tour+1 et la variable coup = 0
tour = tour + 1;
coup = 0;}
{ myGLCD.setColor(255,0,0);//désignation de la couleur
myGLCD.setFont(BigFont);
myGLCD.print(tour, CENTER, 150);
}}}

You can't convert an int to a char. You can convert an int to a string - a NULL terminated ARRAY OF chars.

Which line does the compiler complain about? Details like that ARE important.

Why is your code full of useless curly braces?

Only ONE curly brace belongs on any line.

You wasted bandwidth posting a picture of text. Why?

Obviously, the myGLCD.print() method (as if you would be using anyone else's GLCD) takes a string. The itoa() function knows how to convert an int to a string.
