Qwiic Dynamic NFC/RFID Tag (SPX-19035)
DESCRIPTION
The STMicroelectronics ST25DV dynamic Near Frequency Communication / Radio Frequency Identification tag ICs are awesome! The ST25DV64KC offers 64-kBit (8-kBytes) of EEPROM memory which can be accessed over both I2C and RF (NFC)! It's a state-of-the-art tag which conforms to ISO/IEC 15693 or NFC Forum Type 5 recommendations. You can read and write the tag's memory using NFC even while the tag is powered down or disconnected!
意法半導體ST25DV動態近頻通信/射頻識別標籤IC非常棒！ST25DV64KC 提供 64 千位 （8 千位元組） 的 EEPROM 記憶體，可通過 I2C 和射頻 （NFC） 訪問！這是一個最先進的標籤，符合 ISO/IEC 15693 或 NFC 論壇類型 5 的建議。您可以使用NFC讀取和寫入標籤的記憶體，即使標籤斷電或斷開連接也是如此！
The EEPROM memory can be divided into four areas, each of which can have different levels of protection applied. Want to store your data so everyone has read and write access over both I2C and RF? You can do that. In fact, that's the default. Want to store your data in an area which can only be read if you know the password, and cannot be written to (via RF)? You can do that too!
EEPROM記憶體可分為四個區域，每個區域都可以應用不同級別的保護。想要存儲您的數據，以便每個人都可以通過I2C和 RF 進行讀寫訪問？你可以做到這一點。事實上，這是預設設置。想要將數據存儲在只有在知道密碼時才能讀取且無法寫入（通過RF）的區域嗎？你也可以這樣做！
Our Arduino Library provides all of the methods you need to read and write the user memory, control the read and write permissions, alter the area sizes and apply password control. Not only that! We've included extra methods which will let you read and write NDEF (NFC Forum Data Exchange Format) URI, WiFi and Text records which your smart phone can understand! We've tested it with ST's "NFC Tap" App - available from the Apple App Store and Google Play. For Android users, we can also recommend wakdev's NFC Tools.
我們的Arduino庫提供了讀取和寫入用戶記憶體，控制讀取和寫入許可權，更改區域大小和應用密碼控制所需的所有方法。不僅如此！我們提供了額外的方法，可讓您讀取和寫入您的智能手機可以理解的NDEF（NFC論壇數據交換格式）URI，WiFi和文本記錄！我們已經使用意法半導體的“NFC Tap”應用程式對其進行了測試 - 可從蘋果應用商店和谷歌Play獲得。對於安卓用戶，我們還可以推薦瓦克德夫的NFC工具。
Do you want your project to be able to log up to 8-kBytes of data (via I2C) and then be able to read it using your smart phone - even if your project is powered off? Our library lets you do that!
您是否希望您的項目能夠記錄多達8千位元組的數據（通過I2C），然後能夠使用智慧手機讀取它 - 即使您的專案已關閉電源？我們的圖書館可以讓你做到這一點！
Do you want to be able to write WiFi credentials (SSID and Password) into tag memory using your smart phone and then to be able to read them over I2C so your Arduino board can join the network? With our library you can do that too!
您是否希望能夠使用智能手機將WiFi憑據（SSID和密碼）寫入標籤記憶體，然後能夠通過I2C讀取它們，以便您的Arduino板可以加入網路？使用我們的圖書館，您也可以做到這一點！
Do you want to be able to manufacture and test your product and then program it with keys or other credentials just before you ship? We've got you covered.
您是否希望能夠製造和測試您的產品，然後在發貨前使用密鑰或其他憑據對其進行程式設計？我們已經為您準備好了。
Are you developing equipment or appliances for the home? Would you like to store diagnostic information so that the repair engineer can access it using their smart phone? Our library lets you do that! Would you like the customer to be able to read the diagnostics with their smart phone and then email them to you? Our library will let you do that too! (Apart from the email bit - obvs.. You will need to add that bit yourself.)
您是否正在為家庭開發設備或電器？您是否希望存儲診斷資訊，以便維修工程師可以使用其智慧手機訪問它？我們的圖書館可以讓你做到這一點！您是否希望客戶能夠使用其智慧手機讀取診斷資訊，然後通過電子郵件將其發送給您？我們的圖書館也會讓你這樣做！（除了電子郵件位 - 訃告。您需要自己添加該位。
Are you designing a poster for your project? Do you want to be able to program your tag using Arduino and then stick it to your poster so people can interact with it? Hey, we've got you covered there too!
您正在為您的項目設計海報嗎？您是否希望能夠使用Arduino對標籤進行程式設計，然後將其粘貼到海報上，以便人們可以與之互動？嘿，我們也把你覆蓋在那裡！
