16-bit Real-Time FFT Demo on an 8bit AVR (ATMega88 @8Mhz)
This is a 64-point Fast Fourier Transform sampling at ~9.8 kS/s using 16-bit mathsss.
The brain is an Atmel ATMega88 running at 8Mhz.
Display is an OLED “ 128 x 64 SSD1308 (similar to SSD1306) using SPI (Bit-Banged).
FTT takes to run, uses ~11% code space & ~25% data space.
To make use of the FFT’s output takes considerably more time and space.
Audio input is through a Condenser Mic with a Butterworth filter (-3db ~7khz).
This is my “version 3“ FFT code. (All code in assembly language).
