The USB HID keyboard driver is about to report through the upper half rather than through a character device of its own, which changes what read() returns from a byte stream to struct keyboard_event_s. Ten in-tree configurations have an application that consumes the byte stream. Add INPUT_KEYBOARD_BYTESTREAM, which renders each event with the keyboard codec instead of copying the event structure, so those applications keep working while they are converted. Only the press events are rendered. A byte stream has no way to say that a key came up, which is exactly what a keyboard reporting through a character device has always delivered, so this reproduces the previous behaviour rather than adding to it.

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.
