Part Number: TRF7970A
Other Parts Discussed in Thread: CC3100

Hello everybody , 

I m using a CortexM4  and would like to use NFClink package to design a reader  with TRF7970A   . I would like NFClink package  to be able to use its  features and robustness .

is there anything ready to use  on M4 ?     I cannot find  NFClink on M4   , where should I look ? 

any other suggestion  ?  I m looking for a complete protocol package  not just basic examples .

thank you

regards

Carlo

    Hello Carlo,

    The NFCLink NCI package is a 3rd party solution and the only example provided for it is on the MSP430 platform. Porting that package to an M4 MCU may be possible but not trivial, and is not something we will support beyond providing a .lib file specifically for the chosen M4 platform.

    The NFCLink NCI solution also should only be used in host-based systems which need to rely on the NCI protocol such as interfacing with an OS like Windows or Android.

    If a complete protocol solution is desired, the NFCLink Standalone firmware should be looked at. This firmware is as robust, if not more so, than NFCLink NCI, has been updated more recently, provides full source code, has full app note documentations, and most important exists on an ARM M4 Platform as the stack has been ported to MSP432. See our App notes:

    There also is a stack example for TM4C using TI-RTOS. That example also includes the CC3100, so there would need to be some effort to separate out the WiFi portions from the NFC portions, but that is also an option. See this TI Design: www.ti.com/.../tidm-tm4c129xnfc
