SparkFun RED-V Thing Plus
=========================

.. contents::

Hardware
--------

Platform :ref:`platform_sifive`: SiFive brings the power of open source and software automation to the semiconductor industry, making it possible to develop new hardware faster and more affordably than ever before. 

.. list-table::

  * - **Microcontroller**
    - FE310
  * - **Frequency**
    - 320MHz
  * - **Flash**
    - 16MB
  * - **RAM**
    - 16KB
  * - **Vendor**
    - `SparkFun <https://www.sparkfun.com/products/15799?utm_source=platformio.org&utm_medium=docs>`__


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

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

.. code-block:: ini

  [env:sparkfun_thing_plus_v]
  platform = sifive
  board = sparkfun_thing_plus_v

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

.. code-block:: ini

  [env:sparkfun_thing_plus_v]
  platform = sifive
  board = sparkfun_thing_plus_v

  ; change microcontroller
  board_build.mcu = fe310

  ; change MCU frequency
  board_build.f_cpu = 320000000L

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`.

SparkFun RED-V Thing Plus has on-board debug probe and **IS READY** for debugging. You don't need to use/buy external debug probe.
