WeMos D1 ESP-WROOM-02 | ||
===================== | ||
|
||
.. contents:: | ||
|
||
Hardware | ||
-------- | ||
|
||
Platform :ref:`platform_espressif8266`: 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** | ||
- ESP8266 | ||
* - **Frequency** | ||
- 80MHz | ||
* - **Flash** | ||
- 2MB | ||
* - **RAM** | ||
- 80KB | ||
* - **Vendor** | ||
- `WeMos <https://artofcircuits.com/product/esp-wroom-02-wifi-18650-battery-charger-board?utm_source=platformio.org&utm_medium=docs>`__ | ||
|
||
|
||
Configuration | ||
------------- | ||
|
||
Please use ``d1_wroom_02`` ID for :ref:`projectconf_env_board` option in :ref:`projectconf`: | ||
|
||
.. code-block:: ini | ||
[env:d1_wroom_02] | ||
platform = espressif8266 | ||
board = d1_wroom_02 | ||
You can override default WeMos D1 ESP-WROOM-02 settings per build environment using | ||
``board_***`` option, where ``***`` is a JSON object path from | ||
board manifest `d1_wroom_02.json <https://github.com/platformio/platform-espressif8266/blob/master/boards/d1_wroom_02.json>`_. For example, | ||
``board_build.mcu``, ``board_build.f_cpu``, etc. | ||
|
||
.. code-block:: ini | ||
[env:d1_wroom_02] | ||
platform = espressif8266 | ||
board = d1_wroom_02 | ||
; change microcontroller | ||
board_build.mcu = esp8266 | ||
; change MCU frequency | ||
board_build.f_cpu = 80000000L | ||
Uploading | ||
--------- | ||
WeMos D1 ESP-WROOM-02 supports the following uploading protocols: | ||
|
||
* ``espota`` | ||
* ``esptool`` | ||
|
||
Default protocol is ``esptool`` | ||
|
||
You can change upload protocol using :ref:`projectconf_upload_protocol` option: | ||
|
||
.. code-block:: ini | ||
[env:d1_wroom_02] | ||
platform = espressif8266 | ||
board = d1_wroom_02 | ||
upload_protocol = esptool | ||
Debugging | ||
--------- | ||
:ref:`piodebug` currently does not support WeMos D1 ESP-WROOM-02 board. | ||
|
||
Frameworks | ||
---------- | ||
.. list-table:: | ||
:header-rows: 1 | ||
|
||
* - 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_esp8266-nonos-sdk` | ||
- The non-OS SDK provides a set of application programming interfaces (APIs) for core ESP8266 functionalities such as data reception/transmission over Wi-Fi, TCP/IP stack functions, hardware interface functions and basic system management functions | ||
|
||
* - :ref:`framework_esp8266-rtos-sdk` | ||
- ESP8266 SDK based on FreeRTOS, a truly free professional grade RTOS for microcontrollers |
