'SDA1' undeclared

[o7-machinehum]

Here is an very basic broken project. For some reason Wire1 is being included when it shouldn't be.

I've been using the U8g2 library with Atmega1284P without any issues before. However, I've included an older version of the library.

Try this instead, and see if it helps:

lib_deps =
