arch/xtensa: add support for capture driver on ESP32 and ESP32|S3| Squashed: Initial settings for MCPWM Capture on board level Created lower half files - compilation ok Using capture debug features. Simple example on fops works Successful duty and freq calculation Documentation update Fixed and added interupt capabilities for all 3 capture channels Cleaned defconfig Renamed macros, added S3 options and moved arch source to common dir Added support for ESP32S3 Added capture example to defconfig and renamed Basic bring up ready. New Kconfig options for motor. Good motor registration Working on enabling pwm generators Working on enabling pwm generators Added fops functions Success on PWM 50% stable pwm operation for bdc Added loopback option for testing Improved rules on fsm Working motor direction control Testing new ISR for fault handling Issues on fault ISR Removed fault implementation (not working) Added support for esp32s3 Documentation improvements Added default motor spin direction Added parameter change while running Review fixes arch/xtensa: add support for fault signal on motor control Squashed: Initial settings for MCPWM Capture on board level Created lower half files - compilation ok Using capture debug features.

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.
