Hello hello, I’m doing a project where I have to use a MLX90614 thermometer in conjunction with a stamp micro controller. However the product parallax made, https://solarbotics.com/product/35003/
Has unfortunately been discontinued and I can’t really get my hands on enough of the models to accomplish what I wish to achieve. Now im using the one made from melexis. http://www.melexis.com/Infrared-Thermometer-Sensors/Infrared-Thermometer-Sensors/MLX90614-615.aspx and it doesn’t have the processor in it to easily communicate to the micro controller. Long story short, I talked to tech support and I was in formed that that means that all the sample code and diagrams are effectively useless. I was wondering if anyone had experience with using this model and could help me use it with the basic stamp microcontroller.

    Unfortunately, the MLX90614 is designed to work initially in SMBus mode (I2C bus) and has a lower limit for the clock signal at 10KHz which the BS2 can't do (it has to do I2C in subroutines and these are too slow). Any of the BS2p models could be used to talk I2C using the built-in I2C statements.

    There is a ready-to-go object in the Propeller Object Exchange that handles the MLX90614 directly (see here).
