platformio and mysensors for atmega328p on breadboard?

  • Hi all,

    I am new to MySensors, and I have only limited experience with platformio and Arduino programming in general.

    I was able to get the temperature sensor built with a Nano and an NRF24L01+ I had laying around -- worked great! As usual, I used platformio to manage the dependencies and the build (I don't care much for the Arduino editor or library and board manager).

    Now I want to make a version of the same sketch using an atmega328p on a breadboard. I figure it should work as it's the same MCU.

    However, I'm running into a slew of errors, mostly "not declared in this scope." My INO file is identical to the one from the temp sensor tutorial.

    In file included from .piolibdeps/MySensors_ID548/MySensors.h:257:0,
    from rf24_temp/src/tempsensor.ino:38:
    .piolibdeps/MySensors_ID548/core/MyTransport.cpp: In function 'void stInitTransition()':
    .piolibdeps/MySensors_ID548/core/MyTransport.cpp:80:45: error: 'hwReadConfigBlock' was not declared in this scope

    .piolibdeps/MySensors_ID548/core/MyTransport.cpp:347:18: error: 'hwMillis' was not declared in this scope
    return hwMillis() - _transportSM.stateEnter;

    So far I've found a few useful links:

    What I've tried (with a pio run target=clean before each attempted build):

    • Adding #include <Arduino.h> to the top of my sketch (nothing changes)
    • Specifying build_flags = -I/path/to/MySensors
    • Specifying lib_ignore = MySensors

    I'm using:

    • MacOS 10.13.1
    • platformio 3.4.1
    • MySensors 2.1.1

    My platformio.ini:

    platform = atmelavr
    board = 328p8m
    framework = arduino
    upload_protocol = usbasp
    lib_deps = 
    build_flags = -I../MySensors
    lib_ignore = MySensors

    Any ideas? Again, this builds fine with the same code but using a nano as the target platform, just won't build for the atmega328p for some reason.

    Hi, welcome to the mysensors forum.

    About your problem, I'm not entirely sure that is mysensors related. Have you asked in the platformio forum?

  • @gohan -- thanks! Sorry for the delayed response, thought I had email notifications for replies set up, but I guess not. Yeah, I'm not sure either, but I've used platformio for a number of other projects without running into this issue, so I thought there might be people here using MySensors with platformio that could perhaps shed some light.

    I'll ask over at their community forum first, and if I don't have any luck will likely make issues at both repos.

    I have installed the mysensors lib from platformio (platformio lib install xx, or something like that)

    And my platformio.ini file look like this:

    platform = atmelavr
    framework = arduino
    board = pro8MHzatmega328

    I think you could remove the build_flags and the lib_ignore

  • Solved with some changes in the Dallas temp library (and platformio 3.5 which allows installing a library from a git url).
