Hardware
--------

Platform :ref:`platform_nxplpc`: The NXP LPC is a family of 32-bit microcontroller integrated circuits by NXP Semiconductors. The LPC chips are grouped into related series that are based around the same 32-bit ARM processor core, such as the Cortex-M4F, Cortex-M3, Cortex-M0+, or Cortex-M0. Internally, each microcontroller consists of the processor core, static RAM memory, flash memory, debugging interface, and various peripherals.

.. list-table::

  * - **Microcontroller**
    - LPC1347
  * - **Frequency**
    - 72MHz
  * - **Flash**
    - 64KB
  * - **RAM**
    - 12KB
  * - **Vendor**
    - `Solder Splash Labs <https://developer.mbed.org/platforms/DipCortex-M3/?utm_source=platformio.org&utm_medium=docs>`__


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

Please use ``lpc1347`` ID for :ref:`projectconf_env_board` option in :ref:`projectconf`:

.. code-block:: ini

  [env:lpc1347]
  platform = nxplpc
  board = lpc1347

You can override default DipCortex M3 settings per build environment using
``board_***`` option, where ``***`` is a JSON object path from
board manifest `lpc1347.json <https://github.com/platformio/platform-nxplpc/blob/master/boards/lpc1347.json>`_. For example,
``board_build.mcu``, ``board_build.f_cpu``, etc.

.. code-block:: ini

  [env:lpc1347]
  platform = nxplpc
  board = lpc1347

  ; change microcontroller
  board_build.mcu = lpc1347

  ; change MCU frequency
  board_build.f_cpu = 72000000L


Uploading
---------
DipCortex M3 supports the following uploading protocols:

* ``jlink``
* ``mbed``

Default protocol is ``mbed``

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

.. code-block:: ini

  [env:lpc1347]
  platform = nxplpc
  board = lpc1347

  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`.

DipCortex M3 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.
