  • Hello,

    I am having trouble using this MPL3115A2 with an Arduino Fio v2 (https://www.sparkfun.com/products/10116). I have hooked it up as instructed (without resistors since it's a 3.3V board) and installed the library. The example of the library gives me obviously wrong measurements for temperature and pressure (way overestimated). I tried with a Arduino Uno and it work perfectly with the exact same parameters (setOversampleRate(x), for instance) so it's not a problem of calibration. I'm therefore guessing thats something's wrong with the I2C protocol, but I can't figure out what. Can anyone help me ?

    Thanks, RĂ©mi
