Some problems of using PNEV5180B V2.0 SPI interface

lakie — Mon, 12 Oct 2020 13:00:55 GMT

When I use PNEV5180B, I hope to get the NCI commands for understand NCI protocol easily. so I connect the SPI interface (J301) to the logic analyzer and use cockpit to send some commands like "Activate Layer3" to PNEV5180B.

When I clicked the "Activate Layer3" button, I captured some data from the MOSI like below:

00 28 00 00 00 00 11 0D 8D 11 0D 8D ...

The data does not accord with NCI specification.

The data from MISO always "0xFF".

so my question is what the format of the data and how to capture the NCI command with PNEV5180B?

Hi,

Hope you are doing well. The PN5180 does not work with NCI commands.

What you see is how the host (LPC) communicates with the PN5180. You can find more information about this communication in section 11.4 of the Data Sheet.

If you are interested, our PN7150 is a full NFC controller solution with integrated firmware and NCI interface.

Best Regards,

Ricardo
