u-blox C030-N211 IoT Starter Kit
================================

.. contents::

Hardware
--------

Platform :ref:`platform_ststm32`: The STM32 family of 32-bit Flash MCUs based on the ARM Cortex-M processor is designed to offer new degrees of freedom to MCU users. It offers a 32-bit product range that combines very high performance, real-time capabilities, digital signal processing, and low-power, low-voltage operation, while maintaining full integration and ease of development.

.. list-table::

  * - **Microcontroller**
    - STM32F437VG
  * - **Frequency**
    - 180MHz
  * - **Flash**
    - 1MB
  * - **RAM**
    - 256KB
  * - **Vendor**
    - `u-blox <https://os.mbed.com/platforms/ublox-C030-N211/?utm_source=platformio.org&utm_medium=docs>`__


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

Please use ``ublox_c030_n211`` ID for :ref:`projectconf_env_board` option in :ref:`projectconf`:

.. code-block:: ini

  [env:ublox_c030_n211]
  platform = ststm32
  board = ublox_c030_n211

You can override default u-blox C030-N211 IoT Starter Kit settings per build environment using
``board_***`` option, where ``***`` is a JSON object path from
board manifest `ublox_c030_n211.json <https://github.com/platformio/platform-ststm32/blob/master/boards/ublox_c030_n211.json>`_. For example,
``board_build.mcu``, ``board_build.f_cpu``, etc.

.. code-block:: ini

  [env:ublox_c030_n211]
  platform = ststm32
  board = ublox_c030_n211

  ; change microcontroller
  board_build.mcu = stm32f437vg

  ; change MCU frequency
  board_build.f_cpu = 180000000L


Uploading
---------
u-blox C030-N211 IoT Starter Kit supports the next uploading protocols:

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

Default protocol is ``mbed``

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

.. code-block:: ini

  [env:ublox_c030_n211]
  platform = ststm32
  board = ublox_c030_n211

  upload_protocol = mbed

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`.

u-blox C030-N211 IoT Starter Kit does not have on-board debug probe and **IS NOT READY** for debugging. You will need to use/buy one of external probe listed below.

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

    * - Name
      - Description

    * - :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.

    * - :ref:`framework_stm32cube`
      - STM32Cube embedded software libraries, including: The HAL hardware abstraction layer, enabling portability between different STM32 devices via standardized API calls; The Low-Layer (LL) APIs, a light-weight, optimized, expert oriented set of APIs designed for both performance and runtime efficiency.
