Stopwatch Micro v0.4.0

The first public binary release of Stopwatch Micro, an unofficial Codex Micro-compatible firmware
for the M5Stack StopWatch Dev Kit (ESP32-S3).

Highlights

  • Six tactile circular controls: Plan, New Task, Fast, Fork, Approve, and Decline.
  • A touch-sensitive reasoning arc for changing and selecting reasoning effort.
  • A central status dial showing Codex quota remaining, reset countdown, and watch battery.
  • Wireless quota updates over paired Bluetooth HID; USB is not required for daily use.
  • Always-on AMOLED with periodic pixel shifting.
  • Persistent BLE bonding and hardened automatic reconnection.
  • Windows backup, build, flash, restore, diagnostics, wireless bridge, and logon-startup tools.

One-time Codex Desktop setup

Open Settings → Codex Micro and configure:

  1. Dial → Reasoning only
  2. Enable Use separate microphone keys
  3. Assign independent ACT11 to New Task
  4. Confirm Analog Up → Toggle plan mode

These mappings are stored by Codex Desktop rather than by the firmware.

Wireless quota bridge

python -m pip install hidapi
.\tools\stopwatch.ps1 bridge -Transport bluetooth
.\tools\bridge_autostart.ps1 install

The bridge uses the desktop-managed Codex App Server and current login. It requires no separate API
key and copies no authentication token. The watch can run from its battery with USB disconnected.

Validation

Validated with ESP-IDF 5.5.4, Windows, Codex Desktop 26.820.7780.0, and the 16 MiB flash / 8 MiB
PSRAM M5Stack StopWatch ESP32-S3:

  • HAL self-test: 17/17
  • Controls: 13/13
  • BLE ready/connected/protocol: 1/1/1
  • 50 Hz transport: 151/151, zero dropped reports
  • Wireless quota frames: zero rejected
  • Host suite: pass=10 skip=1 failures=0

Download the ZIP and .sha256 file, verify the checksum, and read FLASHING.md. Preserve a complete
factory backup before the first installation. The ZIP includes all firmware images, flashing tools,
bridge helpers, manifest, checksums, license, and third-party notices.

Stopwatch Micro v0.4.0 中文版

Stopwatch Micro 的首个公开二进制版本：面向 M5Stack StopWatch Dev Kit（ESP32-S3）的非官方
Codex Micro 兼容固件。

主要功能

  • 六个具有分层质感和按压反馈的圆形按钮：Plan、New Task、Fast、Fork、Approve、Decline。
  • 顶部弧形触控区可调整并选择推理强度。
  • 中央状态圆盘显示 Codex 剩余额度、重置倒计时和手表电量。
  • 通过已配对的 Bluetooth HID 无线更新额度，日常使用不需要 USB。
  • AMOLED 常亮，并通过周期性像素漂移降低静态画面磨损。
  • BLE 绑定持久保存，增强断线和重新上电后的自动重连。
  • 提供 Windows 备份、构建、刷机、恢复、诊断、无线桥接和登录自启动工具。

Codex Desktop 一次性设置

打开 Settings → Codex Micro：

  1. 设置 Dial → Reasoning only
  2. 开启 Use separate microphone keys
  3. 将独立的 ACT11 分配为 New Task
  4. 确认 Analog Up → Toggle plan mode

这些映射保存在 Codex Desktop 中，而不是固件内。

无线额度桥接

python -m pip install hidapi
.\tools\stopwatch.ps1 bridge -Transport bluetooth
.\tools\bridge_autostart.ps1 install

桥接程序使用 Codex Desktop 管理的 App Server 和当前登录状态，不需要单独的 API Key，也不会
复制认证令牌。拔掉 USB 后，手表仍可依靠电池运行并持续更新额度。

验证结果

已使用 ESP-IDF 5.5.4、Windows、Codex Desktop 26.820.7780.0，以及 16 MiB Flash / 8 MiB
PSRAM 的 M5Stack StopWatch ESP32-S3 验证：

  • HAL 自检：17/17
  • 控制项：13/13
  • BLE ready/connected/protocol：1/1/1
  • 50 Hz 传输：151/151，零丢包
  • 无线额度帧：零拒绝
  • Host 测试：pass=10 skip=1 failures=0

请下载 ZIP 和 .sha256 文件，校验后阅读包内 FLASHING.md；首次安装前应保存完整原厂备份。
ZIP 包含全部固件镜像、刷机工具、桥接助手、manifest、校验值、许可证和第三方声明。
