UPDATE: Seemed to answer my own question. Surely it can't be that convoluted to just add a library to an existing project and have it function normally?! I've used PICs in the past and coming to Atmel I've found horrible documentation and a weird super-slick super-fly whizz bang interface that can't leave well enough alone and obfuscates simple function. The 'Add Library' dialog box in Atmel Studio is awful, it seems. I also can't find a way to add something by right clicking the project and clicking 'Add.' It wants me to find. I tried this tutorial and still no dice: I've searched for answers to this problem and I find long tutorials about changing the compiler settings for the project, the linker settings, etc. I don't want Atmel Studio to control my libraries by wrapping them up in some 'library project' or somethig, I want to put them in a folder of my choosing and add them when I need them. So, this is probably a stupid problem to have. Why should it matter that functions are in an external library, now the compiler doesn't understand what those data types mean? I also get many error messages of the type 'unknown type name int16_t/uint16_t/uint8_t/etc.' That part is really baffling to me. h file are apparently undefined as far as the compiler is concerned. All of the things that are defined in the.

However, this doesn't work! I get an exceedingly long list of errors. I put them into the src folder under the project name. Then copy these files into the solution in Atmel Studio. Copy the appropriate functions/definitions into each file. I would have OLED.h and OLED.c for functions that control an OLED display. I started writing a test program for a prototype PCB, and now that it's grown to nearly 1000 lines I'm trying to break it up into libraries that I can use for particular functions. I know there are a lot of questions on this topic, and I've looked through a fair number of them.
