Progress in USB driver Nothing is working yet. But just getting this in here so it is saved. Minor changes with USB power enabled Serial over USB is working now. Removed stm32_usbdev.c, added stm32_usbfs.c. Still needs review before pull-request. Rewrote VDDUSB valid check to use register definitions. Wait for USB33RDY before moving on. Also style updates. Renamed stm32_usbdev files to stm32_usbfs. Renamed STM32H5 configuration options from STM32H5_USB to STM32H5_USBFS. Properly named REGDEBUG defines. Added STM32H5_USB_REGDEBUG to Kconfig and updated stm32_usbfs.c to use it. TRACE functionality still needs work. Updated REGDEBUG for 32-bit register accesses. More style updates. Added usbnsh defconfig to nucleo-h563zi Update to allow 16 buffers (max for 8 endpoints). Renamed lpinterrupt and lptransfer. Changed board.h to use SYNCSRC_USB only if USB is enabled. Buffer size is still set to max packet size of 64 bytes, because we are using a full-speed peripheral. It is unclear to me whether having a buffer larger than the max packet size has any benefit. Double buffering is a way to increase throughput, though that still needs to be implemented. Adapted USBFS Buffer table for 32-bit accesses. Style updates Build stm32_hsi48.c based on CONFIG_STM32H5_HAVE_HSI48. Change LPMODE CNTR bit to SUSPRDY. |

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.

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.
