WavePhoenix – open-source implementation of the Nintendo WaveBird protocol

a year ago

The WaveBird controller is highly regarded for its wireless capability, long battery life, and comfort.
An open-source implementation of the Nintendo WaveBird protocol was developed using Silicon Labs Wireless Gecko SoCs.
The project includes firmware components like libwavebird (WaveBird protocol), libsi (SI protocol), receiver firmware, and a bootloader.
Hardware design focuses on affordability and ease of building, featuring a PCB with an RF-BM-BG22C3 module and a 3D printable case.
The WaveBird protocol uses DSSS (Direct Sequence Spread Spectrum) with 15 chips per bit for robust communication.
Silicon Labs Wireless Gecko EFR32FG1 SoCs were chosen for their hardware support of the required modulation.
The project overcame challenges in packet decoding and radio configuration to achieve near-original performance.
Features include channel selection, virtual pairing, and support for multiple controllers on the same channel.
Potential future enhancements include transmitter firmware, N64 WaveBird receiver, and USB HID dongle support.
The project acknowledges contributions from the community and is licensed under MIT for firmware and Solderpad Hardware License v2.1 for hardware.
