Hi,
I'm working on a project involve controlling multiple MLX90614 from parallax. I've got one sensor worked thanks to TC_Chu's Point website
However, when i try to put on another one (pretty much copy and paste to new function). Sensors doesn't seem to read at all (nothing print out on command window). Could anyone give me some hint on where i could do things wrong?
Thank you so much
