This commit introduces a software-based fake capture driver that simulates a 10Hz square wave with 50% duty cycle, enabling development and testing of capture-related applications without requiring real hardware. Background: The capture driver subsystem requires hardware support (timers with input capture functionality) to measure external signal frequency and duty cycle. During development, testing, or on platforms without capture hardware, it's difficult to develop and test applications that use the capture API. Problem: Without a fake/simulator driver: - Developers cannot test capture applications without specific hardware - Continuous Integration (CI) systems cannot run capture-related tests - Applications cannot be developed on platforms lacking capture hardware - Testing edge notification features requires complex hardware setup - Difficult to reproduce specific timing scenarios for debugging Solution: This commit provides a software-simulated capture driver that generates predictable capture events using a watchdog timer. The fake driver produces a square wave signal at 10Hz frequency with 50% duty cycle, allowing applications to test the full capture API without hardware.

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.
Contributing
If you wish to contribute to the NuttX project, read the Contributing guidelines for information on Git usage, coding standard, workflow and the NuttX principles.
