Undefined reference to initUSART

[hexagon5un]

Sorry for the late reply.

Studio does strange things. Are you using the Studio makefile or mine? If Studio's, then it won't know where to find the additional headers and code that lives in AVR-Programming-Library/

As you noticed, the easiest way to fix everything with Studio is just to copy the contents of the AVR-Programming-Library/ folder into each and every project's folder.

There must also be a way to add additional code/library folders to the project, but I haven't used Studio extensively in like 10 years.

Hope you've gotten it working in the meantime. Let me know?

Hope all worked out. :)
