Advanced Zephyr RTOS kernel services. Covers inter-thread communication using Zbus (pub/sub), behavioral management with the State Machine Framework (SMF), background processing via work queues, and persistent configuration with the Settings subsystem. Trigger when building modular application architectures, complex state-driven logic, or requiring persistent data storage.

怎么用

商店整理自技能原文 · 版本 ed63cdf · 表述以原文为准
它做什么

这个技能让Claude能够协助你使用Zephyr RTOS的Zbus（发布/订阅）、状态机框架（SMF）、工作队列和设置子系统，构建模块化、事件驱动的嵌入式应用。

什么时候触发

当你需要开发模块化架构、复杂状态逻辑或持久化存储时，这个技能会自动激活并提供指导。

装好后可以这样说
Claude会给出Zbus通道定义和发布/订阅的示例代码。
Claude会使用SMF框架创建状态表并给出过渡逻辑。
Claude会介绍Settings子系统的用法。

Zephyr Kernel Services

Move beyond basic threading and logging to build modular, event-driven, and robust Zephyr applications.

Core Workflows
1. Event-Driven Communication (Zbus)

Decouple your modules using a lightweight publish-and-subscribe bus.

  • Reference: [zbus.md](references/zbus.md)
  • Key Tools: ZBUS_CHAN_DEFINE, ZBUS_SUBSCRIBER_DEFINE, zbus_chan_pub.
2. Behavioral Logic (SMF)

Manage complex system states and transitions using the State Machine Framework.

  • Reference: [smf.md](references/smf.md)
  • Key Tools: smf_set_state, SMF_CREATE_STATE, Hierarchical states.
3. Background Processing (Work Queues)

Defer long-running or non-critical tasks to prevent blocking interrupts or high-priority threads.

  • Reference: [settings_workqueue.md](references/settings_workqueue.md)
  • Key Tools: k_work_submit, k_work_delayable, Custom work queues.
4. Persistence (Settings)

Save and restore configuration data and state across reboots.

  • Reference: [settings_workqueue.md](references/settings_workqueue.md#settings-subsystem)
  • Key Tools: settings_load, settings_save_one, NVS backends.
Quick Start (Zbus)
// Define a channel for sensor data
ZBUS_CHAN_DEFINE(sensor_data_chan, struct sensor_msg, NULL, NULL, ZBUS_OBSERVERS_EMPTY, ZBUS_CHAN_DEFAULTS);

// Publish from a thread
zbus_chan_pub(&sensor_data_chan, &msg, K_NO_WAIT);
Professional Patterns (Asset Tracker Style)
  • Modularity: Use Zbus as the backbone for inter-module communication.
  • Predictability: Use SMF to define clear lifecycle states for each module (e.g., Uninitialized -> Ready -> Active -> Error).
  • Responsiveness: Use custom work queues for sensor data ingestion to keep the main thread responsive for cloud communication.
  • Sensor Integration: For sensor data ingestion patterns, see the [hardware-io](../hardware-io/SKILL.md) skill.
Automation Tools
  • [zbus_channel_lint.py](scripts/zbus_channel_lint.py): Detect duplicate ZBUS_CHAN_DEFINE names across source files.
Examples & Templates
  • [smf_state_table_template.c](assets/smf_state_table_template.c): Starter SMF state table and lifecycle wiring.
Validation Checklist
  • [ ] Zbus publishers and subscribers exchange messages without deadlock or missed updates.
  • [ ] SMF transitions follow expected state graph under normal and error conditions.
  • [ ] Deferred work executes on intended queue context with bounded execution time.
  • [ ] Settings values persist across reboot and reload successfully at startup.
