One of [Dooievriend]’s friends recently pressed him into service to write software for a 3d spectrum analyzer/VU that he made. The VU is a fairly complex build: it’s made up of 1280 LEDs in a 16x16x5 ...

This project implements the fft algorithm on the Spartan 3E FPGA (Papillio One Platform) which in turn is used as a spectrum analyzer with some added hardware (e.g. ADC).

You can create a release to package software, along with release notes and links to binary files, for other people to use. Learn more about releases in our docs.
