Replace the divergent board conventions for the timer input clock frequency with a single uniform convention provided by every board: - STM32_APBx_TIMn_CLKIN and BOARD_TIMn_FREQUENCY -> STM32_TIMn_CLKIN - STM32_APBx_LPTIMn_CLKIN, BOARD_LPTIMn_FREQUENCY and STM32_LPTIMn_FREQUENCY -> STM32_LPTIMn_CLKIN - STM32_APB1_THRTIM1_CLKIN and BOARD_HRTIM1_FREQUENCY -> STM32_HRTIM1_CLKIN All STM32 consumers (tim/lptim/pwm/adc/dac/capture/sdadc/dfsdm/ pulsecount) updated to match; the timer input clock is now bus-agnostic in the drivers. Boards that carried the same timer clock in more than one convention now define STM32_TIMn_CLKIN exactly once, derived from the APB bus clock (PCLKx with the x2 doubler when the APB prescaler is greater than 1), instead of redefining it with a second, sometimes different, value. BREAKING CHANGE: The timer input-clock board macros STM32_APBx_TIMn_CLKIN, BOARD_TIMn_FREQUENCY, STM32_APBx_LPTIMn_CLKIN, BOARD_LPTIMn_FREQUENCY, STM32_LPTIMn_FREQUENCY, STM32_APB1_THRTIM1_CLKIN and BOARD_HRTIM1_FREQUENCY are removed in favor of STM32_TIMn_CLKIN, STM32_LPTIMn_CLKIN and STM32_HRTIM1_CLKIN. Out-of-tree boards must define the new macros (drop the APB bus from the name, keep the value), and out-of-tree drivers referencing the old names must be updated.

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.
