Generic ESP8266
|
||
|
|
===============
|
||
|
|
|
||
|
|
All ESP8266-based devices are supported by esphomeyaml. Simply select ``ESP8266`` when
|
||
|
|
the esphomeyaml wizard asks you for your platform and choose a board type
|
||
|
|
from `this link <http://docs.platformio.org/en/latest/platforms/espressif8266.html>`__ when the wizard
|
||
|
|
asks you for the board type.
|
||
|
|
|
||
|
|
|
||
|
|
.. code:: yaml
|
||
|
|
|
||
|
|
# Example configuration entry
|
||
|
|
esphomeyaml:
|
||
|
|
name: livingroom
|
||
|
|
platform: ESP8266
|
||
|
|
board: <BOARD_TYPE>
|
||
|
|
|
||
|
|
Many boards have a pin numbering for the exposed pins that is different from the internally used
|
||
|
|
ones. esphomeyaml tries to map the silk-screen pin numbers into the internal pin numbers with a few
|
||
|
|
boards, but for generic ESP8266 boards it is often required to just use the internal pin numbers.
|
||
|
|
To do this, just prefix all pins with ``GPIO``, for example ``GPIO0`` for the pin with the internal pin
|
||
|
|
number 0.
|
||
|
|
|
||
|
|
Some notes on the pins:
|
||
|
|
|
||
|
|
- ``GPIO6`` - ``GPIO11``, ``GPIO0``, ``GPIO2`` and ``GPIO15`` are often already used by the internal
|
||
|
|
flash interface and boot mode detection. So it's best to avoid using these pins.
|
||
|
|
- ``GPIO17`` additionally has an ADC connected to it. See the :doc:`/esphomeyaml/components/sensor/adc`
|
||
|
|
to read out voltages (in the range from 0 to 1.0V) on this pin.
