And this is the Arduino Code:

/***************************************************************************
 

This is a library for the AMG88xx GridEYE 8x8 IR camera

This sketch tries to read the pixels from the sensor

Designed specifically to work with the Adafruit AMG88 breakout

These sensors use I2C to communicate. The device’s I2C address is 0x69

Here’s my arduino code for the amg8833, note, in the processing code, match “COM3” or whatever number to what the serial port is in the Arduino IDE

#include <Wire.h>
#include <Adafruit_AMG88xx.h>

Adafruit_AMG88xx amg;

float pixels[AMG88xx_PIXEL_ARRAY_SIZE];


float Tmax = 36.0;  //what max and min temps are (actually 0-80)
float Tmin = 16.0;
float valMax = 5.0; //values that processing uses to map the colors
float valMin = 1.0;

float range = (Tmax - Tmin);  //used to normalize to range 2
float range2 = (valMax - valMin);
float pix;
int resetPin = 12;

void setup() {
  digitalWrite(resetPin, HIGH);
  delay(200);
  pinMode(resetPin, OUTPUT);
  Serial.println("RESET");
  
  
  Serial.begin(115200);

  bool status;

  // default settings
  status = amg.begin();
  if (!status) {
    Serial.println("Could not find a valid AMG88xx sensor, check wiring!");
    while (1);
  }



  delay(100); // let sensor boot up
}


void loop() {
  //read all the pixels
  amg.readPixels(pixels);


  for (int i = 0; i < AMG88xx_PIXEL_ARRAY_SIZE; i++) {
    pix = (abs((pixels[i] - Tmin)) / range);
    if (pix >= 0 && pix <= 1) {
      Serial.print(((pix * range2) + valMin), 3);
      Serial.print(',');
    } else {
      delay(10);
      digitalWrite(resetPin, LOW);
    }
  }


  Serial.println();
  //delay a second
  delay(100);
}

@DZR please can you format your code as @kfrajer asked?

@kfrajer

Please provide your latest code. No screenshots. Copy and paste, select code and hit the </> button before publishing your post so to format your code.

You can still edit your code to do so.

Thanks

[DZR]

I thought I had done that. See above. “Preformatted text”

[DZR]

Ok. I think I followed your instructions from your email. Thank you for the reply. I appreciate any help.

[DZR]

Can someone help me please?

In the line “Pixels[i-1]/10” You’ll want to change that to ((Pixels[i-1]/20)+1). Because, as I said, you want a number between 1 and 5 and the range it can read is from 0-80, so you should only expect those values. and just dividing by 10 alone doesnt properly normalize it
