Lots of errors when trying to compile example sketch



  • Hi,

    i have wired a gateway node with an NRF2401+ radio and a W5100 ethernet module and an Arduino nano. Pretty much like the tutorial.
    So now i want to flash the arduino. I have downloaded the 2.0.0 library and imported the zipfile as a library in the Arduino software. I have copy&pasted the example sketch for this type of gateway, and tried to compile it. But i get LOTS of errors according to code in the library itself. Let me show you:

    Error compiling for board Arduino Nano.
    

    So my question is now: How can i resolve these issues? I am quite sure that you didn't commit faulty code, so it's somehow an error on my side...but where am i wrong?


  • Mod

    @simonszu on my mobile now so I have trouble reading everything but try changing name of the Mysensors-master folder to just MySensors


  • Mod

    The easiest way to install the MySensors library is to use the Board Manager. See https://www.mysensors.org/about/arduino#installing-the-sensor-libraries for instructions. You'll need to delete the folder that was added manually first though.
