I've been looking for a while inside Arduino's files to find the core library. However, I haven't found them yet. Where on my hard drive can I obtain the core library files (.cpp and .h) necessary for all Arduino code?
Looking around on Google, I couldn't find a way to find the above files. I did see something about getting an .a file while Arduino is compiling, however, that isn't what I want. I want to browse the code and look at functions such as delay to see how they would react when given the values not expected. (i.e. Will my code stall if I use
delay(-200); by not being to exit the loop, or will it create a black hole and disrupt the space-time continuum?)
