This program is the full source code in displaying temperatures measured from an MLX90640 thermal camera. The camera is a 32 x 24 sensor array, but this program will scale the display up to 310 x 230 through interpolation. Color mapping between temperatures and a 565 color palet is used for displaying data. Other features are legends with a temperature gradient and a histogram showing temperatur frequencies. Other controls let the user set the temperatue, range, and refresh rate.
This porgram was tested using a Teensy 4.0 and ILI9341-based display. It is highly unlikely this program can be ported to use an Arduino, as they will probably not have enough memory or computing power.
