WEMOS LOLIN D32 PRO
===================

.. contents::

Hardware
--------

Platform :ref:`platform_espressif32`: Espressif Systems is a privately held fabless semiconductor company. They provide wireless communications and Wi-Fi chips which are widely used in mobile devices and the Internet of Things applications.

.. list-table::

  * - **Microcontroller**
    - ESP32
  * - **Frequency**
    - 240MHz
  * - **Flash**
    - 4MB
  * - **RAM**
    - 320KB
  * - **Vendor**
    - `WEMOS <https://wiki.wemos.cc/products:d32:d32_pro?utm_source=platformio.org&utm_medium=docs>`__


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

Please use ``lolin_d32_pro`` ID for :ref:`projectconf_env_board` option in :ref:`projectconf`:

.. code-block:: ini

  [env:lolin_d32_pro]
  platform = espressif32
  board = lolin_d32_pro

You can override default WEMOS LOLIN D32 PRO settings per build environment using
``board_***`` option, where ``***`` is a JSON object path from
board manifest `lolin_d32_pro.json <https://github.com/platformio/platform-espressif32/blob/master/boards/lolin_d32_pro.json>`_. For example,
``board_build.mcu``, ``board_build.f_cpu``, etc.

.. code-block:: ini

  [env:lolin_d32_pro]
  platform = espressif32
  board = lolin_d32_pro

  ; change microcontroller
  board_build.mcu = esp32

  ; change MCU frequency
  board_build.f_cpu = 240000000L


Uploading
---------
WEMOS LOLIN D32 PRO supports the next uploading protocols:

* ``esp-prog``
* ``espota``
* ``esptool``
* ``iot-bus-jtag``
* ``jlink``
* ``minimodule``
* ``olimex-arm-usb-ocd``
* ``olimex-arm-usb-ocd-h``
* ``olimex-arm-usb-tiny-h``
* ``olimex-jtag-tiny``
* ``tumpa``

Default protocol is ``esptool``

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

.. code-block:: ini

  [env:lolin_d32_pro]
  platform = espressif32
  board = lolin_d32_pro

  upload_protocol = esptool

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`.

WEMOS LOLIN D32 PRO 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.
