Wifi NINA Module

Use my sketch for VidorNinaSerialPassthrough. It was based on this code: https://gist.github.com/sameer/6ee696303579798d2e20c9ab7e52a088

Communicate using command line esptool.

Software Setup

Arduino code

Inside the ArduinoSketch directory, there is the MusicJukebox project which contains the code to program the Arduino along with bitstream generated from FpgaProject

FPGA code

The FpgaProject directory is the project to be opened in Quartus IDE. After generating the bitstream, run convert_bitstream.sh to convert the bitstream into an Arduino header file.
