The GPIO interrupt handler had hardcoded values that only worked correctly for RP2350A (30 GPIOs). For RP2350B (48 GPIOs): - Loop count was hardcoded to 6 registers but should be computed based on RP23XX_GPIO_NUM (4 for RP2350A, 6 for RP2350B) - Reserved bits mask was always applied at register index 3, but for RP2350B register 3 contains valid GPIOs 24-31. This caused interrupts for GPIOs 30-31 to be incorrectly discarded - PWM port validation rejected valid ports 8-11 on RP2350B which has 12 PWM slices instead of 8 Changes: - Add RP23XX_GPIO_NREGS macro to compute number of interrupt registers - Use conditional compilation to only mask reserved bits on RP2350A where the last register has 6 valid GPIOs (bits 0-23) - Fix PWM port validation to allow 12 ports on RP2350B Signed-off-by: paolo <paolo.volpi@gmail.com> |

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.
