In development
Your glasses’ firmware. Booting on a Mac.
A full-system emulator for RayNeo iO smart glasses. A Renode board model and a native Swift viewer, aimed at booting the unmodified stock firmware and showing its real display output.
Unofficial · MIT licensed · No firmware distributed
Why
Stop flashing for every change.
Iterate safely
Boot the firmware you already own on your laptop, as many times as you like, with no risk to the glasses.
Learn the hardware honestly
Every peripheral model is written from what the firmware actually does on the emulated bus, not from guesses dressed up as results.
No patched instructions
The goal is to run the stock image as-is. When something fails, the model gets fixed, not the firmware.
Boot progress
Stock firmware, booting on a Mac.
The stock firmware enters NuttX on the emulated CPU, runs board init, mounts storage and shows its boot logo in a Mac window. Next stop: bring up the BTH subsystem and boot all the way to the home screen.
How it works
A virtual board. A native window.
Scripts turn your firmware into an installed-format flash image and run it on a BES1700 board model in Renode. The display controller model scans out the frame buffer the firmware actually wrote, and a Swift Mac app shows that frame in a window.
Quick start
Four commands.
You need macOS 14 or later, the Xcode command line tools, Python 3 and Renode (MIT licensed, installed separately, not bundled).
git clone https://github.com/owenc1122/rayneo-io-on-mac.git && cd rayneo-io-on-mac
swift test # unit tests
sh scripts/build-app.sh # builds "build/RayNeo io on Mac.app"
sh scripts/run-app.sh # boots .local/firmware.bin and shows the display
sh scripts/emulate.sh <ota-files-dir> 15 # headless run, 15 s of emulated timeBring your own firmware from your own device or another lawful source and keep it under .local/ (ignored by Git). The scripts only read it and never modify it.
