README
README.mdPHYLLO · 声音生长成光
让声音沿着“向日葵”的黄金角排列变成光。PHYLLO把浏览器音频演示、STM32信号处理、144灯PCB与可拆卸外壳放在同一个工程中，共用一份几何与灯链数据，便于从画面追溯到代码和设计文件。
原项目保存的候选结构渲染，不是实板照片；电路、制造、接线、打印配合与实物性能仍待验证。
状态与功能
开发中：采购前数字工程，软件可独立体验，硬件未实测。 本次开源整理不启动EDA、不改变原设计、不制造或烧录。
- 浏览器演示黄金角阵列、三种空间灯效与配色；支持合成信号及本地音频分析。
- 固件核心实现去直流、Hann窗、512点FFT、RMS、七频段能量和谱通量节拍检测。
- STM32F411候选工程包含I2S DMA、音频队列、灯链映射、WS2812 DMA输出与串口遥测。
- PCB、原理图、可读电路图、参数化机械源与自有打印件模型可审阅。
- 网页设备区只读显示串口状态；浏览器动画不代表实体设备已正常工作。

|---|---|
| 网页 | 原生JavaScript、Canvas、Web Audio、Web Serial；Node.js 18+用于本地服务/测试，无npm运行依赖 |
| 可移植核心 | C11、GCC、CMake 3.20+、Ninja、数学库 |

快速体验网页
git clone https://github.com/yangwei251003/phyllotaxis.git
cd phyllotaxis
node web/server.mjs打开 http://127.0.0.1:8765/，默认合成信号即可体验，不需要麦克风或硬件。麦克风需要浏览器授权；音频在本地处理。Web Serial需要支持该API的浏览器和安全上下文，不能笼统承诺所有手机可用。
仓库配置了GitHub Pages静态发布工作流，启用后可从 在线演示 直接体验。网页展示与实体硬件验收是两件事。
测试可移植固件核心
需要GCC、CMake与Ninja已在PATH中：
cmake -S firmware -B .runtime/host -G Ninja -DCMAKE_C_COMPILER=gcc
cmake --build .runtime/host
ctest --test-dir .runtime/host --output-on-failure网页单元测试与本地HTTP检查：
cd web
node --test tests/*.test.mjs
cd ..
python scripts/smoke-web.py可选：离线构建F411候选
需要Git、Python 3、CMake、Ninja及 arm-none-eabi-gcc/objcopy/nm/size 在PATH：
python firmware/bootstrap_sources.py
python firmware/build_candidate.pybootstrap只下载锁定版本的官方源码并检查提交/哈希，遇到本地修改会停止，不重置源码。供应商目录和编译输出已忽略。此命令不连接、枚举、烧录或操作开发板；候选输出不构成烧录放行。真实板型、麦克风槽位、数据时序、供电、温升和灯链需要后续实物核实。

Questions
How big is the Phyllo copper review PCB?
It measures 180 × 180 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Phyllo copper review use?
171 parts, built around the 74AHCT1G125GW,125-JSM, WS2812B-B-V6, APXF100ARA271MF61G and B4B-XH-A-G. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Phyllo copper review KiCad files?
From the yangwei251003/phyllotaxis repository on GitHub, at the commit this page was made from: the board is hardware/prototype-v02/phyllo-copper-review.kicad_pcb and its schematic hardware/kicad-check/phyllo-copper-review.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Phyllo copper review design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
