GitHub / delhatch / Spectrum

Spectrum analyzer system using a 512-point FFT, in a Cyclone IV FPGA. Reads i2s audio from the codec and then does all FFT/VGA functions. Nios just reads the FFT result and draws the display bars. VGA frame buffer on-chip. VGA signals generated on-chip. See the included video files to watch it in action.
