If you ended up here, I think you likely got an error like what is pictured above. For some reason your avr-gcc library doesn't include the header files for the ATTiny1608 or ATTiny808 processors. But the good news is you can just download a few files (like from here) drop them in the right place and then everything will work.

Extracting the fundamental frequency from a time-domain signal

"Extracting the fundamental frequency from a time-domain signal" is basically a long-winded way of saying "demodulating the baseband signal from FM-encoded signal". Well, that's still long winded, but I digress.

In an FM radio, the contraption that accomplishes this task is referred to as a "discriminator". So the task here is to implement a software-based frequency discriminator. There are a few different ways

	/// You must specify the size of the chamfer, the height of the child
