feather tft thermal camera
I use the interpolated pixel thermal camera program with the TFT 2.4" with AMG88xx Featherwing + ESP8866. It works well and see the temperature patterns for 28 deg.C. When I change this value to 50,it stops working What should I do to extend the temperature rang from RT to 50 ?

Re: feather tft thermal camera
Please precisely explain what you mean by "stops working".
You are using the "Thermal Cam Featherwing" example in Arduino?

Yes
On line #85: #define MINTEMP = 30 (my current RT)
Line #88 MAXTEMP= 38
The display stays blue even if I put my hand in front of the detector.
I also would like a larger range of temperature, up eventually to 80C. even with a temperature step larger.
Is that possible?

Re: feather tft thermal camera
The way it works is that it maps the reading to a value 0-255 based on your min & max values then uses that to look up the color. What temperatures are you reading? If they are below your minimum, it'll get clipped to 0 after mapping and be blue.
