IoT node reference design supporting Wi-Fi® functionality and NFC connection switching

TIDM-TM4C129XNFC

Overview

Configuration of Wi-Fi network connection parameters in embedded applications can be completed with a simple tap using NFC technology. This reference design illustrates how to perform NFC connection switching (pairing) and URL sharing on a Wi-Fi node using the TM4C1294 high-performance microcontroller, the CC3100 network processor, and the TRF7970A NFC transceiver or RF430CL330H NFC transponder.

characteristic

● TM4C1294 MCU host and CC3100 network processor serve as Wi-Fi HTTP server
● Wi-Fi HTTP server used as access point or site
● CC3100 implements Wi-Fi stack to simplify TM4C1294 host processor application
● HTML code to remotely control TM4C1294 MCU via web browser
● TRF7970A NFC transceiver shares pairing information and HTTP server URL in access point mode
● RF430CL330H NFC transponder receives pairing information in station mode and shares HTTP server URL
