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 [1].
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 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 --shield arduino_uno_click when you invoke west build with
other mikroBUS shields. For example:
# From the root of the zephyr repository
west build -b sam_v71_xult/samv71q21 --shield arduino_uno_click --shield atmel_rf2xx_mikrobus samples/net/sockets/echo_server -- -DEXTRA_CONF_FILE=overlay-802154.conf
