  • Melexis MLX90632 Thermopile

    I'm trying to make heads or tails of the necessary I2C calls to get this to continuously output the raw sensor data. Not sure if there's a general call necessary but also the registers involved seem a bit buried or maybe I'm just not getting it. .PDF attached

    Keith, It looks like you can place the device into CONTINOUS triggering mode but, you will have to set the address each time you retrieve the 6 results.

    The sequence should look like the following:



    Write new_data = 0


    Check when new_data = 1


    Read cycle_pos to get measurement pointer


    If cycle_pos = 1


    Calculate TA and TO based on RAM_4, RAM_5, RAM_6, RAM_9


    If cycle_pos = 2


    Calculate TA and TO based on RAM_7, RAM_8, RAM_6, RAM_9


    Return to top

      Thanks, I'll see if I can make sense of what you're saying by finding those registers. I am also just looking for the raw data and the low byte at that.
