The rp23xx common board sources reference rp23xx_st7735.c from both Make.defs and CMakeLists.txt under CONFIG_LCD_ST7735, but the file was never added. Enabling CONFIG_LCD_ST7735 on any rp23xx board therefore fails the build on the missing source. Add the file, modelled on the existing RP2040 sibling boards/arm/rp2040/common/src/rp2040_st7735.c and retargeted to rp23xx/SPI1. It implements board_lcd_initialize(), board_lcd_getdev() and board_lcd_uninitialize(): bring up SPI1, claim the D/C (shared with the unused SPI1 RX pad, per the rp23xx common convention), RST and BL pads as GPIO, pulse the panel reset and bind the ST7735 driver. Validated on silicon on a Waveshare RP2350-LCD-0.96 (RP2350A + ST7735S 160x80 IPS): the panel powers up and displays correctly, painted at boot with no console interaction. Build-tested raspberrypi-pico-2:nsh with CONFIG_LCD_ST7735=y (compiles and links). Assisted-by: Claude (Anthropic Claude Code) Signed-off-by: Ricard Rosson <ricard@groundbits.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.
