sduino MB (STM8S208MBT6B)
=========================

.. contents::

Hardware
--------

Platform :ref:`platform_ststm8`: The STM8 is an 8-bit microcontroller family by STMicroelectronics an extended variant of the ST7 microcontroller architecture. STM8 microcontrollers are particularly low cost for a full-featured 8-bit microcontroller.

.. list-table::

  * - **Microcontroller**
    - STM8S208MBT6
  * - **Frequency**
    - 16MHz
  * - **Flash**
    - 128KB
  * - **RAM**
    - 6KB
  * - **Vendor**
    - `sduino <https://github.com/roybaer/sduino_mb?utm_source=platformio.org&utm_medium=docs>`__


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

Please use ``mb208`` ID for :ref:`projectconf_env_board` option in :ref:`projectconf`:

.. code-block:: ini

  [env:mb208]
  platform = ststm8
  board = mb208

You can override default sduino MB (STM8S208MBT6B) settings per build environment using
``board_***`` option, where ``***`` is a JSON object path from
board manifest `mb208.json <https://github.com/platformio/platform-ststm8/blob/master/boards/mb208.json>`_. For example,
``board_build.mcu``, ``board_build.f_cpu``, etc.

.. code-block:: ini

  [env:mb208]
  platform = ststm8
  board = mb208

  ; change microcontroller
  board_build.mcu = stm8s208mbt6

  ; change MCU frequency
  board_build.f_cpu = 16000000L


Uploading
---------
sduino MB (STM8S208MBT6B) supports the next uploading protocols:

* ``serial``
* ``stlinkv2``

Default protocol is ``serial``

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

.. code-block:: ini

  [env:mb208]
  platform = ststm8
  board = mb208

  upload_protocol = serial

Debugging
---------
:ref:`piodebug` currently does not support sduino MB (STM8S208MBT6B) board.

Frameworks

    * - 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_spl`
      - The ST Standard Peripheral Library provides a set of functions for handling the peripherals on the STM32 Cortex-M3 family. The idea is to save the user (the new user, in particular) having to deal directly with the registers.
