| .. zephyr:board:: particle_argon |
| |
| Overview |
| ******** |
| |
| The Particle Argon is a Wi-Fi enabled development board with a Nordic |
| Semiconductor nRF52840 for mesh support and an ESP32 for Wi-Fi. The |
| board was developed by Particle Industries and has a SWD connector on it |
| for programming. |
| |
| It is equipped with a onboard LIPO circuit and conforms to the |
| Adafruit Feather formfactor. |
| |
| The Particle Argon provides support for the Nordic Semiconductor nRF52840 ARM |
| |reg| Cortex |reg|-M4F SoC with an integrated 2.4 GHz transceiver supporting |
| Bluetooth |reg| Low Energy and IEEE |reg| 802.15.4. |
| |

| - `Argon Hardware Files`_ |
| |
| Hardware |
| ******** |
| |
| On the front of the board are RGB-LED, LED and LIPO circuitry. |
| The RGB-LED is controlled by the nRF52840 via GPIO pins. |
| |
| Power supply |
| ============ |
| |
| The board is optimized for low power applications and supports two |
| power source configurations: battery and micro USB connector. |
| |
| It contains circuitry for LIPO usage and can be charged via the USB port. |
| |

| Connections and IOs |
| =================== |
| |
| Please see the `Argon Datasheet`_ for header pin assignments, which are |
| common to all Feather-compatible Particle boards. Some peripherals are |
| available to applications through DTS overlay include directives: |
| |
| - ``mesh_feather_i2c1_twi1.dtsi`` exposes TWI1 on labeled Feather |
| SDA1/SCL1 pins |
| - ``mesh_feather_spi_spi1.dtsi`` exposes SPI1 on labeled Feather |
| SPI pins |
| - ``mesh_feather_spi_spi3.dtsi`` exposes SPI3 on labeled Feather |
| SPI pins |
| - ``mesh_feather_spi1_spi3.dtsi`` exposes SPI3 on labeled Feather |
| SPI1 pins |
| - ``mesh_feather_uart1_rtscts.dtsi`` adds hardware flow control to |
| labeled Feather UART pins |

| Programming and Debugging |
| ************************* |
| |
| .. zephyr:board-supported-runners:: |
| |
| Applications for the ``particle_argon`` board configuration can be |
| built and flashed in the usual way (see :ref:`build_an_application` |
| and :ref:`application_run` for more details). |
| |
| Flashing |
| ======== |
| |
| Build and flash an application in the usual way, for example: |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/basic/blinky |
| :board: particle_argon |
| :goals: build flash |
| |
| Debugging |
| ========= |
| |
| You can debug an application in the usual way. Here is an example for the |
| :zephyr:code-sample:`hello_world` application. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: particle_argon |
| :maybe-skip-config: |
| :goals: debug |
| |
| |
| Testing the LEDs and buttons |
| **************************** |
| |
| There are 2 samples that allow you to test that the buttons (switches) and |
| LEDs on the board are working properly with Zephyr: |
| |
| * :zephyr:code-sample:`blinky` |
| * :zephyr:code-sample:`button` |
| |
| You can build and flash the examples to make sure Zephyr is running correctly on |
| your board. |
