hello all, i've been busy working on getting the mlx90640 sensor working better. and it does. it works faster on arm devices, and it works reasonably well on arduino. the code from the ground up has modifications that are designed to work on multiple processors. when i did the amg8833 optimizations i only gave consideration to the atmega and the nano and uno. 

i'm going to start to modify the library within the next week or so to ensure it is compatible with arm processors. i will also take what i have learned in optimizations from the i2c and also include a terminal output graphics mode in the amg8833 code and ability to output 8x8 -128x128 data on terminal both in graphics mode and in deg c. so some exciting stuff coming up soon.
