Dear all,
I am trying out AMG8833 thermal cam with arduino mega and UTFT ILI9341 library. I tried to use the original code with minimal modifications for UTFT. The result was a slow, misshapen thing whose grid produces nothing like an image of an object. Can anyone tell me if there is limitation for this arduino card and or the libraries. Attached is the adapted code.
Thanks for any help
Cesar
#include <UTFT.h>
#include <URTouch.h>
UTFT tft(ILI9341_16,38,39,40,41); //Parameters should be adjusted to your Display/Schield model
URTouch myTouch( 6, 5, 4, 3, 2);
extern uint8_t SmallFont[];
#define YAXIS 0 //Axis of the TFT sceen
#define XAXIS 1
#include <Adafruit_AMG88xx.h>

//low range of the sensor (this will be blue on the screen)
#define MINTEMP 20
//high range of the sensor (this will be red on the screen)
//#define MAXTEMP 28

//the colors we will be using
