Multiple errors in my code [Solved]

My code:

#include <SoftwareSerial.h>

SoftwareSerial myUART(0, 1); 

#include <Adafruit_TFTLCD.h> 
#include <Adafruit_GFX.h>    
#include <TouchScreen.h>

#define LCD_CS A5 
#define LCD_CD A4 
#define LCD_WR A7 
#define LCD_RD A8 
#define LCD_RESET A6 

#define BLACK    0x0000
#define BLUE     0x001F
#define RED      0xF800
#define GREEN    0x07E0
#define CYAN     0x07FF
#define MAGENTA  0xF81F
#define YELLOW   0xFFE0 
#define WHITE    0xFFFF

Adafruit_TFTLCD tft(LCD_CS, LCD_CD, LCD_WR, LCD_RD, LCD_RESET);

void setup() {
  
  myUART.begin(115200);  
  
  tft.reset();
  uint16_t identifier = tft.readID();
  tft.begin(identifier);
  -------------------------------------
  tft.setRotation(0);
  tft.fillScreen(WHITE);


  tft.setCursor(30,40); //Tal vez haya que cambiar la posicion
  tft.setTextColor(BLACK);
  tft.setTextSize(2);
  tft.print("CONTROLADOR REYMI");
  
 tft.setCursor(5,120);
 tft.setTextColor(BLACK);
 tft.setTextSize(1);
 tft.print("Corriente:");  


 tft.setCursor(5,100);
 tft.setTextColor(BLACK);
 tft.setTextSize(1);
 tft.print("Temperatura:");  
  

}

void corriente(){

 float c_TOTAL = 0;
 int contador = 0;
 int Prom = 10;
 while ( contador < Prom ){
 int c_READ = analogRead (A2); 
 float c_VOLT= c_READ*(5/1023);  
 c_TOTAL += c_VOLT;
 contador +=1;
 }

 float c_CORR = c_TOTAL / Prom;

 String corrString = String(c_CORR)+"mA";
 
 tft.setCursor(10,120); 
 tft.setTextColor(BLACK);
 tft.setTextSize(1);
 tft.print(corrString);
 delay(50);
 
 }

 void temperatura(){


   myUART.println("T?");
   
   while (myUART.available() > 0) {

   char temp = myUART.read();
   delay(50);
   String tempString = String(temp)+"°C";
   tft.setCursor(10,100); // Corrido de donde esta la corriente puesta
   tft.setTextColor(BLACK);
   tft.setTextSize(1);
   tft.print(tempString);
   }

 }

void loop() {

 corriente();
 temperatura();

}

The errros are the following:

C:\Users\Reymi\Documents\Arduino\PE\PE.ino: In function 'void temperatura()':
PE:136:23: error: lvalue required as decrement operand
136 | myUART.println("T?");
| ^
exit status 1

EDIT: Only those two errors are giving me problems now. Thanks to both comments below.

doesn't the UNO have only 6 analog inputs: A0 - A5

3

gcjr:
doesn't the UNO have only 6 analog inputs: A0 - A5

Indeed that was the problem.

Now I only need help with the last two errors.

Start with removing this decorative line of minuses. It's being interpreted by the complier.

  tft.begin(identifier);
  -------------------------------------
  tft.setRotation(0);

 tft.setRotation(0);

Thank you very much sir.

All errors have been solved
