What I want to do is read my MLX90614 IR temperature sensor via my spark core. After struggeling to do this for a while I come here to ask for help. It is possible to read this sensor succesfully via arduino, using some libraries which are not compatible with spark (AVR library is used for instanc…

Hi peekay Thank you. I don’t know why I didn’t look at that, I guess that I thought they would keep those pins compatible with Arduino. Everything is working perfect now. Thanks again Mike

Hi guys, I’m also trying to communicate with this sensor using Arduino Micro board this time. I’ve tried to use the official Adafruit library, but no success. ArduinoMicro uses the following I2C pins 2-SDA(PD0) and 3-SCL(PD1). Of course my sensor is connected with pullups to this pins. I’m always…

Hey @moska2004 , Just wanted to let you know that this forum is about the Spark Devices. Although they share a lot of similarities with Arduinos, they are also very different. It may well be that the code on the Spark does not work on the arduino, and the other way around. Although this community is…

@peekay123 , Is there a tutorial on porting libraries? I’d like to port Adafruit’s MPL115A2 library but not knowing the subtle differences between an Arduino library and what the Photon needs it would challenging for me. Here’s a link to their library. Adafruit MPL3115A2 Library If there’s a tutori…

@tkurtz , search the community for “arduino port” and you will find stuff to help. This library is straight forward to port since it uses I2C which is built into the Photon firmware (no Wire.h required). The board has a regulator and level shifters so power the breakout by connecting Vin (on the bo…

@ScruffR , I did read that other thread and attempted the MPL3115A with the MPL115A2 without success. I believe they are actually different. Would you mind reviewing the library with me so this community can learn more about how to port an i2c library? I haven’t been able to find a good instructional…

@tkurtz , there is no “step-by-step” tutorial. I believe either @ScruffR or I can help you here but he’s a lot smarter than me : :stuck_out_tongue_winking_eye:

[image] peekay123: he's a lot smarter than me : :stuck_out_tongue_winking_eye: Says the one who's about ten times the experience of me (just count the library ports - I've only got three still) But since @peekay123 is already juggling way more balls than I even got, I can have a look …

@ScruffR @peekay123 , Thanks guys! I gave it a good try but I’m resulting in some ugly errors during compile. Here’s a look at my files. Errors point to various issues in the library. Would love to hear your thoughts! :smile: The INO: // This #include statement was automatically added by the Partic…

@tkurtz, if you really mean the MPL3115A lib it’s already on the Web IDE - and as in the other thread my suggestion was to try if it also supports the MPL115A2.
