Can we use PN7160 NFC Reader instead of PN532 Adafruit NFC Reader

[sagarnayakm]

Hello,

In my project, I want to use PN7160 NFC Reader instead of PN532 NFC Reader because in nRF SDK had a library for PN532 but the library is comfortable for PN7160 or not .??

Yes, i can go for PN532 also but they are not recommended for a new design by anybody. So Please let us know if it's comfortable or not.??

Thank You.

Yes, the nRF Connect SDK is built on the Zephyr RTOS, and all applications are built with the Zephyr RTOS in mind. 

If you're not familiar with the nRF Connect SDK I would strongly recommend reading the introduction page of the documentation, and checking out our DevAcademy where we have some courses on how to get started with development on the nRF Connect SDK.

You're currently basing your project on the NFC: Tag reader sample project, correct? It should already use SPI to communicate. For a simpler SPI application you can check out the JEDEC SPI-NOR sample for instance.

Can you explain what you mean about "not getting any clock cycles"? How does the oscilloscope trace look when measuring on I.E. the lines to the ST25's crystal?

Best regards,

Simon

Hello,

Using st25's with nrf52840 dev kit can we use spi0 because spi0 in nrf52840 dev kit disabled so the library example Tag_reader is for spi0 or spi1.??

and please confirm the nrf52840 dev kit spi 0 pins are correct.??

SCLK-(0,27)

MISO-(0,29)

MOSI-(0,26)

CS-(O,12)

IRQ(0,3)

OR 

SCLK-(1,15)

MISO-(1,14)

MOSI-(1,13)

CS-(0,12)

IRQ-(0,3)

I have connected the second spi pins which i mentioned  and in the logic analyzer i got this 

and in NRF terminal
