ST / Mbed 2 deprecated HelloWorld_Async_M24SR

M24SR NFC example. Simple application to asynchronously write and read an URL from a M24SR tag.

Dependencies:   M24SR NDefLib mbed

This simple application provides an example of usage of the M24SR NFC Tag component library.
It is derived from the HelloWorld_Async_NFC01A1 application and currently supports X-NUCLEO-NFC01A1 and ST-Discovery-L475E-IOT01A.
