| Programming and Debugging |
| ************************* |
| |
| Applications for the ``bl653_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 BL653 development board, the FTDI USB should be used to access the UART console. |
| |
| .. code-block:: console |
| |
| $ minicom -D <tty_device> -b 115200 |
| |
| Replace :code:`<tty_device>` with the port where the BL653 development kit |
| 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: bl653_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 BL653 DVK |
| *********************************** |
| Many of the Bluetooth examples will work on the BL653 DVK. |
| Try them out: |
| |
| * :ref:`ble_peripheral` |
| * :ref:`bluetooth-eddystone-sample` |
| * :ref:`bluetooth-ibeacon-sample` |
| |
| |
| Testing the LEDs and buttons on the BL653 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/lairdconnect/bl653_dvk/bl653_dvk.dts`. |
| |
| Using UART1 |
| *********** |
| |
| The following approach can be used when an application needs to use |
| more than one UART for connecting peripheral devices: |
| |
| 1. Add devicetree overlay file to the main directory of your application: |
| |
| .. code-block:: devicetree |
| |
| &pinctrl { |
| uart1_default: uart1_default { |
| group1 { |
| psels = <NRF_PSEL(UART_TX, 0, 14)>, |
| <NRF_PSEL(UART_RX, 0, 16)>; |
| }; |
| }; |
| /* required if CONFIG_PM_DEVICE=y */ |
| uart1_sleep: uart1_sleep { |
| group1 { |
| psels = <NRF_PSEL(UART_TX, 0, 14)>, |
| <NRF_PSEL(UART_RX, 0, 16)>; |
| low-power-enable; |
| }; |
| }; |
| }; |
| |
| &uart1 { |
| compatible = "nordic,nrf-uarte"; |
| current-speed = <115200>; |
| status = "okay"; |
| pinctrl-0 = <&uart1_default>; |
| pinctrl-1 = <&uart1_sleep>; |
| pinctrl-names = "default", "sleep"; |
| }; |
| |
| In the overlay file above, pin P0.16 is used for RX and P0.14 is used for TX |
| |
| 2. Use the UART1 as ``DEVICE_DT_GET(DT_NODELABEL(uart1))`` |
| |
| See :ref:`set-devicetree-overlays` for further details. |
| |
| Selecting the pins |
| ================== |
| |
| Pins can be configured in the board pinctrl file. To see the available mappings, |
| open the `nRF52833 Product Specification`_, chapter 7 'Hardware and Layout'. |
| In the table 7.1.1 'aQFN73 ball assignments' select the pins marked |
| 'General purpose I/O'. Note that pins marked as 'low frequency I/O only' can only be used |
| in under-10KHz applications. They are not suitable for 115200 speed of UART. |
