Adafruit WINC1500 Wifi Shield

#############################

Overview

********

The Adafruit WINC1500 Wifi shield is an Arduino

compatible shield based on the ATWINC1500 wifi controller

from Microchip.

The shield also provides a micro SD card socket

The SD card socket is currently not supported

More information about the shield can be found

at the `Adafruit WINC1500 website`_.

Pins Assignment of the Adafruit WINC1500 WiFi Shield

====================================================

+-----------------------+---------------------------------------------+

| Shield Connector Pin  | Function                                    |

| D13 (a)               | SPI SCK          (Serial Clock Input)       |

+-----------------------+---------------------------------------------+

The pins marked (a) must be jumpered to the SPI port at the shield

To enable low power support, wire the pin marked (b) to the En connector

at the shield

Requirements

************

This shield can only be used with a board which provides a configuration

for Arduino connectors and defines node aliases for SPI and GPIO interfaces

(see :ref:`shields` for more details).

Programming

***********

Set ``-DSHIELD=adafruit_winc1500`` when you invoke ``west build``. For example:

.. zephyr-app-commands::

   :zephyr-app: samples/net/wifi

   :board: frdm_k64f

   :shield: adafruit_winc1500

   :goals: build
