shields: Add arduino uno click shield
The shield converts Arduino UNO R3 headers to two mikroBUS sockets. Two mickoBUS sockets are exposed via the overlay labelled mikrobus_header_1 and mikrobus_header_2. mikrobus_header_1 is used as the default and assigned the node label mikrobus_header.

Arduino UNO click shield | ||
######################## | ||
|
||
Overview | ||
******** | ||
|
||
The Arduino UNO click is an extension to the Arduino UNO R3 headers. | ||
It's a simple shield that converts Arduino UNO R3 headers to two mikroBUS | ||
host sockets that allow you to connect many other click shields to your | ||
board. | ||
In other words, the Arduino UNO click will generally be used by other | ||
shields using the mikroBUS interface. | ||
|
||
Two mikroBUS headers are exposed by the overlay: ``mikrobus_header_1`` and | ||
``mikrobus_header_2``, each corresponding to a socket on the Arduino UNO | ||
click shield. | ||
|
||
The first socket (``mikrobus_header_1``) is the default socket which is | ||
assigned the node label ``mikrobus_header`` in the overlay. | ||
|
||
More information about the shield can be found at | ||
`Arduino UNO click shield website`_. | ||
|
||
Requirements | ||
************ | ||
|
||
This shield can only be used with a board which provides a configuration | ||
for Arduino R3 connector. | ||
|
||
The board must also define node aliases for arduino Serial, | ||
SPI and I2C interfaces (see :ref:`shields` for more details). | ||
|
||
Connecting shields should use the first socket (``mikrobus_header_1``). This | ||
socket is assigned the ``mikrobus_header`` node label. | ||
|
||
Programming | ||
*********** | ||
|
||
Include ``-DSHIELD=arduino_uno_click`` when you invoke ``west build`` with | ||
other mikroBUS shields. For example: | ||
|
||
.. zephyr-app-commands:: | ||
:zephyr-app: samples/net/sockets/echo_server | ||
:host-os: unix | ||
:board: sam_v71_xult | ||
:gen-args: -DOVERLAY_CONFIG=overlay-802154.conf | ||
:shield: "arduino_uno_click atmel_rf2xx_mikrobus" | ||
:goals: build | ||
