HEX

Using Arduino Project Guidance

I have a device that returns RGB color in serial everything is working except it returns it in Hexadecimal here is a example of what I get out of the serial monitor.

code below (I did not make code got it online)

#include <SoftwareSerial.h>

SoftwareSerial Color90(2, 3);

/*====================================================
 / Connect ColorPAL SIG signal to Arduino pin 2 and 3
 / Baud Rate = 9600 kbps
 /
 /====================================================*/

void setup()
{
    pinMode(11, OUTPUT);  
  Serial.begin(9600);
  Color90.begin(4800);

  pinMode(2,INPUT);
  pinMode(3,INPUT);
  digitalWrite(2,HIGH); // Enable the pull-up resistor
  digitalWrite(3,HIGH); // Enable the pull-up resistor

  pinMode(2,OUTPUT);
  pinMode(3,OUTPUT);
  digitalWrite(2,LOW);
  digitalWrite(3,LOW);
  
  pinMode(2,INPUT);
  pinMode(3,INPUT);
  
  Serial.println("Pass 1");
  
  while( digitalRead(2) != HIGH || digitalRead(3) != HIGH ) {
    Serial.println("In the loop");
    delay(50);
  }
  
  Serial.println("Pass 2");

  pinMode(2,OUTPUT);
  pinMode(3,OUTPUT);
  digitalWrite(2,LOW);
  digitalWrite(3,LOW);
  delay(80);
  
  pinMode(2,INPUT);
  pinMode(3,OUTPUT);
  delay(100);  
}

//---------------------------------

void loop()
{
  char rByte[9];
  
  Color90.begin(4800);
   Color90.print("= (00 $ m) !");// Color90.print("= rFFFFFF !");
  pinMode(3,INPUT);

  rByte[0] = Color90.read();
  if( rByte[0] == '

) {
    for(int i=0; i<9; i++) {
      rByte[i] = Color90.read();
      Serial.print(rByte[i]);
        digitalWrite(11, HIGH);
       
    }
   
    Serial.println();
  }

delay(500);
    digitalWrite(11, LOW);    // set the LED off
}

See http://arduino.cc/en/Serial/Print

I think you want to change this line:

      Serial.print(rByte[i]);

to:

      Serial.print(rByte[i], DEC);

but you really haven't stated what you're asking for.

the hex should have three values. I need to turn them into 3 int variables (should be from 0-255) I took all the char and instead of printing them I saved all of them to a string.

so long story short how do I convert a string with Hexadecimal in it to a regular decimal (int)

4

when doing the above it returns really long string

484857484848484850

Put some spaces between the values ==>
48 48 57 48 48 48 48 48 50
Then, consult an ASCII table ==>
0 0 9 0 0 0 0 0 2
Now, can you figure out how to get 9, 0, 2 from that?
