Hello! I'm a new member!
So, I have an EVK1104 with AT32UC3A3256S microcontroller. I must build a guitar tuner with that, so I need to do a FFT into microcontroller to get fundamental frequency. The microphone that I use is MAX9814.
Guitar note has this frequency range: 0-1000Hz. I want to get foundamental frequency with 1 Hz resolution (maybe I should use 4096 samples).
There is any library that can help me? Or anyone can give me any advice?
