this is my setup pin. i connect my rs pin to dc pin, are they have same function?

#include "SPI.h"
#include <Adafruit_GFX.h>
#include <ILI9488.h>

#define TFT_CS 12
#define TFT_DC 11//my lcd pin RS
#define TFT_RST 13
ILI9488 tft = ILI9488(TFT_CS, TFT_DC, TFT_RST);

Use the wireing like in the example. Arduino SPI Pins are defined in Hardware you cant use 10/11/12/13 like you want.

#define TFT_CS 10
#define TFT_DC 9
#define TFT_RST 12

SCK is 13, 11 is Data.
