Connections and IOs =================== LED --- * LED1 (blue) = P0.13 * LED2 (blue) = P0.14 * LED3 (blue) = P0.15 * LED4 (blue) = P0.16 Push buttons ------------ * BUTTON1 = SW1 = P0.11 * BUTTON2 = SW2 = P0.12 * BUTTON3 = SW9 = P0.24 * BUTTON4 = SW10 = P0.25 * RESET = SW3 = nReset/IF BOOT Programming and Debugging ************************* Applications for the ``bl654_dvk`` board configuration can be built, flashed, and debugged in the usual way. See :ref:`build_an_application` and :ref:`application_run` for more details on building and running. Flashing ======== Follow the instructions in the :ref:`nordic_segger` page to install and configure all the necessary software. Further information can be found in :ref:`nordic_segger_flashing`. Then build and flash applications as usual (see :ref:`build_an_application` and :ref:`application_run` for more details). Here is an example for the :ref:`hello_world` application. First, run your favorite terminal program to listen for output. NOTE: On the BL654 DVK, the FTDI USB should be used to access the UART console. .. code-block:: console $ minicom -D -b 115200 Replace :code:`` with the port where the board nRF52 DK can be found. For example, under Linux, :code:`/dev/ttyUSB0`. Then build and flash the application in the usual way. .. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: bl654_dvk :goals: build flash Debugging ========= Refer to the :ref:`nordic_segger` page to learn about debugging Nordic based boards with a Segger IC. Testing Bluetooth on the BL654 DVK *********************************** Many of the Bluetooth examples will work on the BL654 DVK. Try them out: * :ref:`ble_peripheral` * :ref:`bluetooth-eddystone-sample` * :ref:`bluetooth-ibeacon-sample` Testing the LEDs and buttons on the BL654 DVK ************************************************ 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. The button and LED definitions can be found in :zephyr_file:`boards/arm/bl654_dvk/bl654_dvk.dts`.
