Alan Carvalho de Assis e73dd2a9a9 boards/sim: register /dev/mouse0 when CONFIG_SIM_MOUSE is enabled
The X11 mouse emulation driver (arch/sim/src/sim/sim_mouse.c) is built
and fed by the X11 event loop whenever CONFIG_SIM_MOUSE=y, but nothing
ever called sim_mouse_initialize(), so /dev/mouse0 was never registered
and applications could not read any mouse reports.  Since nothing
referenced sim_mouse.o, the linker did not even pull it in and the
build failed with "undefined reference to `sim_mouseevent'".

Call sim_mouse_initialize(0) from sim_bringup(), next to the existing
touchscreen and keyboard initialization.

Tested with sim:nsh + CONFIG_SIM_X11FB, CONFIG_SIM_MOUSE and
CONFIG_SIM_KEYBOARD: /dev/mouse0 is now listed and reports left, middle
and right button state plus pointer motion.

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.
