Компонент Adafruit CC3000 WiFi Shield
В течение многих лет мы видели всевозможные модули Wi-Fi, совместимые с микроконтроллерами, но ни один из них не был по-настоящему достоин Adafruit. Либо они были слишком медленными, либо слишком сложными в использовании, либо требовали подписания соглашения о неразглашении, либо имели ограниченную функциональность, либо были слишком дорогими, либо слишком большими. Поэтому мы отказались от создания или разработки Wi-Fi Arduino shield.БОЛЬШЕ НЕТ! Модель CC3000 идеально подходит по соотношению практичности, цены и возможностей. Он использует SPI для связи (не UART!), так что вы можете передавать данные так быстро, как хотите, или так медленно, как хотите. Он имеет надлежащую систему прерываний с выводом IRQ, так что вы можете иметь асинхронные соединения. Он поддерживает 802.11b / g, open /WEP / WPA / WPA2 security, TKIP и AES. Встроенный стек TCP/IP с интерфейсом "BSD socket". TCP и UDP как в клиентском, так и в серверном режиме, до 4 одновременных сокетов. Он не поддерживает режим "AP", он может подключаться к точке доступа, но не может быть точкой доступа. Пожалуйста, обратите внимание, что модуль CC3000 постепенно выводится из эксплуатации, и мы предлагаем WINC1500 в качестве замены - он имеет поддержку SSL, возможность soft-AP и является более надежным.
