AMG88xx Camera Display

Using Arduino Displays
1

Please correct this code
I am using 3.5'' UNO display driver ili9486 Dots:320x480 Touch:No

Original code file compatible with adafruit 1.44" display is attached. I tried to modify it but it didn't work ... can somebody help me where I am wrong?

This the code I modified for 3.5''. There is an attachment in which original code is attached (adafruit).

Please follow the "how to use this forum" guidelines.

I bet that the original code did not have italics and did not have emoji. Therules are there for a reason.

OK, but "didn't work" isn't very helpful. The code does something. If this something is not the something you were expecting, tell us what you expected and what it actually did.

Can you get the simpler examples to work? Can you print "hello" or anything onto the screen? Can you get any values from the sensor?

Actually I want real time display of thermal image camera AMG88xx on my screen. Adafruit has given us code which is attached (original post). They made for 1.4" display (driver : ST7735) however I am using 3.5" display( driver : ili9486).
Yes by using this code I can print different things.

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

#define LCD_CS A3 
#define LCD_CD A2 
#define LCD_WR A1 
#define LCD_RD A0 
#define LCD_RESET A4 

#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() {

  tft.reset();
  tft.begin(0x9481);
  tft.setRotation(1);
  tft.fillScreen(RED);
  tft.fillScreen(GREEN);
  tft.fillScreen(BLUE);
  tft.fillScreen(BLACK);
  delay(1000);
  tft.setCursor(80,100);
  tft.setTextColor(WHITE);
  tft.setTextSize(4);
  tft.print("Hello");

  tft.setCursor(220,100);
  tft.setTextColor(RED);
  tft.setTextSize(4);
  tft.print("YouTUBE!");

  tft.fillRect(80,200, 321, 60, RED);

  tft.setCursor(135,215);
  tft.setTextColor(WHITE);
  tft.setTextSize(4);
  tft.print("Subscribe");

  tft.drawRect(0,0,480,320,WHITE);
  delay(1000);
}

void loop() 
{
  tft.fillRect(80,200,321,60,BLACK);
  delay(1000);
  tft.fillRect(80,200,321,60,RED);
  tft.setCursor(135,215);
  tft.setTextColor(WHITE);
  tft.setTextSize(4);
  tft.print("Subscribe");
  delay(1000);
}

Thanks

Ok. Step2: are you getting any values from the sensor?

Step3: can you print just one value to the screen as a number?

I suspect the problem is the color array. The two displays likely have a different representation of colors. Try to make it work with brightness levels of a single color.
