I'm working on porting the RFAL for ST25R3916B to an nRF5340, using the pairing example for X-NUCLEO-8. I have it all compiling and flashing correctly, but things break down during initialization here:In rfalInitialize() -> st25r3916Initialize(), the...

Is there any example code for ISO14443A passive target mode, which is supported on the ST25R3916B? I'm prototyping basic functionality before fully implementing our application, and it would be nice to do a proof of concept without having to grapple ...

I'm working on writing drivers to use an ST25R3916B to interface with a non-ST host chip as an NFCIP-1 passive communication initiator. I've made progress on the communication to establish an active connection to a tag, but one part I'm stuck on is ...

Hi Ulysses,I think you're right, but it's not (directly) about the missing CS positive pulse. Here's where I'm at:The host sends a 0x42 to read register 02.An IRQ is sent.The host sends a 0x5A to read this IRQ. Instead of a 0x00 from the ST25 as usua...

Whoops, here's the log file.

Here's the log file, it looks like the self test completes without any issues.I hadn't noticed what Ulysses pointed out; no CS transition after the command may very well be the issue. My CS deselect port doesn't fail anywhere else, but I'm going to t...

I just spent a while researching and that does seem to be correct; most competitor chips have similar operation to the ST25R3916B. (Except an old MediaTek chip for some reason! The MT6605 looks like it would work, but it's not even mentioned on the M...

The intention is to have a device that can scan NFC tags to store IDs, then be out in remote operation for a period of hours to days without necessarily being recharged. When the device is found, still out in the field and out of power, it should sti...
