This commit refactors the logic of workqueue processing delayed and periodic work, and changes the timer to be set in `work_thread`. The improvements of this change are as follows: - Fixed the memory reuse problem of the original periodic workqueue implementation. - By removing the `wdog_s` structure in the `work_s` structure, the memory overhead of each `work_s` structure is reduced by about 30 bytes. - Set the timer for each workqueue instead of each work, which improves system performance. - Simplified the workqueue cancel logic.

Apache NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. Scalable from 8-bit to 64-bit microcontroller environments, the primary governing standards in NuttX are POSIX and ANSI standards. Additional standard APIs from Unix and other common RTOSs (such as VxWorks) are adopted for functionality not available under these standards, or for functionality that is not appropriate for deeply-embedded environments (such as fork()).
For brevity, many parts of the documentation will refer to Apache NuttX as simply NuttX.
Getting Started
First time on NuttX? Read the Getting Started guide! If you don't have a board available, NuttX has its own simulator that you can run on terminal.
Documentation
You can find the current NuttX documentation on the Documentation Page.
Alternatively, you can build the documentation yourself by following the Documentation Build Instructions.
The old NuttX documentation is still available in the Apache wiki.
Supported Boards
NuttX supports a wide variety of platforms. See the full list on the Supported Platforms page.
