Hardware
--------

Platform :ref:`platform_nordicnrf52`: The nRF52 Series are built for speed to carry out increasingly complex tasks in the shortest possible time and return to sleep, conserving precious battery power. They have a Cortex-M4F processor and are the most capable Bluetooth Smart SoCs on the market.

Configuration
-------------

Please use ``delta_dfbm_nq620`` ID for :ref:`projectconf_env_board` option in :ref:`projectconf`:

.. code-block:: ini

  [env:delta_dfbm_nq620]
  platform = nordicnrf52
  board = delta_dfbm_nq620

You can override default Delta DFBM-NQ620 settings per build environment using
``board_***`` option, where ``***`` is a JSON object path from
board manifest `delta_dfbm_nq620.json <https://github.com/platformio/platform-nordicnrf52/blob/master/boards/delta_dfbm_nq620.json>`_. For example,
``board_build.mcu``, ``board_build.f_cpu``, etc.

.. code-block:: ini

  [env:delta_dfbm_nq620]
  platform = nordicnrf52
  board = delta_dfbm_nq620

  ; change microcontroller
  board_build.mcu = nrf52832

  ; change MCU frequency
  board_build.f_cpu = 64000000L


Uploading
---------
Delta DFBM-NQ620 supports the next uploading protocols:

* ``blackmagic``
* ``cmsis-dap``
* ``jlink``
* ``mbed``
* ``nrfjprog``
* ``stlink``

Default protocol is ``cmsis-dap``

You can change upload protocol using :ref:`projectconf_upload_protocol` option:

.. code-block:: ini

  [env:delta_dfbm_nq620]
  platform = nordicnrf52
  board = delta_dfbm_nq620

  upload_protocol = cmsis-dap

Debugging
---------

:ref:`piodebug` - "1-click" solution for debugging with a zero configuration.

.. warning::
    You will need to install debug tool drivers depending on your system.
    Please click on compatible debug tool below for the further
    instructions and configuration information.

You can switch between debugging :ref:`debugging_tools` using
:ref:`projectconf_debug_tool` option in :ref:`projectconf`.

Delta DFBM-NQ620 has on-board debug probe and **IS READY** for debugging. You don't need to use/buy external debug probe.

.. list-table::
    :header-rows:  1

    * - Name
      - Description

    * - :ref:`framework_arduino`
      - Arduino Wiring-based Framework allows writing cross-platform software to control devices attached to a wide range of Arduino boards to create all kinds of creative coding, interactive objects, spaces or physical experiences.

    * - :ref:`framework_mbed`
      - The mbed framework The mbed SDK has been designed to provide enough hardware abstraction to be intuitive and concise, yet powerful enough to build complex projects. It is built on the low-level ARM CMSIS APIs, allowing you to code down to the metal if needed. In addition to RTOS, USB and Networking libraries, a cookbook of hundreds of reusable peripheral and module libraries have been built on top of the SDK by the mbed Developer Community.
