This Near Field Communication (NFC) reference design provides a firmware example for implementing an NFC Peer to Peer (P2P) application. It is used for showing the application developer the correct way to implement a robust peer-to-peer project using the TRF7970A in both active and passive modes. The complexity of the Peer to Peer protocols and amount of NFC documentation that needs to be reviewed has traditionally been a barrier to developers creating NFC applications. This reference design solves this problem by providing a small number (five total) of easy to use Application Programming Interfaces (APIs). The documentation, hardware, and example code provided allows the designer to quickly implement NFC P2P functionality with an MSP430 or other MCU of choice.
Firmware build options available for MSP-EXP430F5529 or MSP-EXP430F5529LP boards
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
