JxOS ├── demo_code — Reference code (unorganized) ├── jxos │ ├── bsp — Legacy classification being migrated to driver and lib │ ├── kernel — Core system functions: tasks, events, messages, mailbox, pipes, memory allocation │ ├── driver — Static initialization modules, hardware-related: sensors, key scanning, displays │ ├── lib — Dynamic initialization modules, hardware-independent: ring buffers, CRC16, stack, software timers │ ├── sys_service — Task-based system services: power management, software timers, print output │ └── std_app — Standard applications: independent key scanning, multiple-click detection, LED blinking ├── platform — Specific projects using different hardware platforms ├── JSnet — Network functions based on JxOS └── SRTnet — Additional network modules

This is the most frequent culprit. Many micro-USB and USB-C cables bundled with consumer electronics only contain wires for power, missing the internal data lines (D+ and D-). Without data lines, the JXMCU chip cannot send its hardware ID to your computer. 2. Driver Signature Enforcement (Windows)

：能够为传感器、按键、显示屏等外设编写驱动代码，并遵循JxOS的静态初始化规范，使用 config.h 进行模块配置。
