Wire the RTL8720F to the shared Ameba I2C master driver (arch/arm/src/common/ameba/ameba_i2c.c), reusing it unchanged. Add the per-chip header arch/arm/src/rtl8720f/ameba_i2c_chip.h supplying the chip's I2C wiring: two controllers (I2C0/I2C1) on their non-secure register aliases (0x401c8000 / 0x401c9000), the APBPeriph function/clock masks, the crossbar SCL/SDA pad-mux codes (59/60 and 61/62), and AMEBA_I2C_HAS_DMA_FIELDS=1 (the chip's I2C_InitTypeDef carries the DMA request-level fields). Add the board glue: rtl8720f_i2c.c registers I2C0 at /dev/i2c0 (PA22/PA23) and I2C1 at /dev/i2c1 (PA24/PA25), plus the build wiring (Make.defs / CMakeLists.txt / ameba_board.mk pull in the common driver and the fwlib ram_common/ameba_i2c.c data-table source), the bringup registration hook and the board header declaration. Add the i2c defconfig (minimal NSH with the i2ctool) and document the config in the board index. Signed-off-by: dechao_gong <dechao_gong@realsil.com.cn> Assisted-by: Claude <noreply@anthropic.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.
