Adafruit_ssd1306 example did not compile

[KurtE]

The library is up at: https://github.com/adafruit/Adafruit_SSD1306

I tried compiling their example for 128x64 spi and first off it did not want to find Wire library... I imported the library again, and then, ran into compile errors.

[Build] Error occurred.

Note: I have edited libraries, but program does build file on Arduino 1.8.2 Teensyduino latest, and T3.6 selected.

It is like it is not autogenerating the appropriate functions forward references.

Fixed, still caused by macro, thanks,

I have the exact same problem now with PlatformIO with latest master. Any idea how to fix?

Ok, I found the problem. The example files are wrong. When I moved the setup() and loop() functions to the end of the file, it worked. You might want to update the examples.

[KurtE]

@buzzy Just an FYI - I currently no longer use Stino as I kept running into memory issues with it and Stino did not follow the same rules as Arduino on which version of library was to be used...

And that @Robot-Will has not updated the code, or issues in over a year and a half.

Thanks ... That solved it for me
