Hi @BartButenaers,  
Thank you for sharing. I haven't try it yet, but my first feedback is:

- can you provide the option for displaying numbers on the canvas, not only colors?
- include at the bottom a legend (from minimum to maximum with colors) similar to the legend in a picture here [https://github.com/sparkfun/SparkFun\_MLX90640\_Arduino\_Example](https://github.com/sparkfun/SparkFun_MLX90640_Arduino_Example)  
Cheers
