Not able to read the UID from tags · 2022-10-19

I'm using an ST MCU (STM32F765VGT6) on a custom board, wired to an X-NUCLEO-NFC06A1 communicating via I2C. I've integrated the RFAL library into an existing codebase. I've taken elements of the Disco demo code into our codebase, to exercise the RFAL....

I copied the code from demo_polling.c from NFC6_V1.1.0. I've attached my thread. I have copied demoCycle() as nfc_reader_process_tags(), which is called from an infinite loop, with a configurable delay between calls. I can't go below a 40ms delay wit...

Hi Ulysses, I removed some printing which could have caused delays along with access to the other I2C device. (and also fixed the ground problem causing those glitches)At 3:77ms, I see it read the FIFO status register, which looks like it says only 2...

Hi Ulysses, Thank you for the I2C tip. I believe I have resolved that part of the issue and am properly accessing the Register B space. However, I still don't see a read of the ID. I've attached another Saleae trace.Should I be getting to the RFAL_NF...

I've attached a capture of a Saleae trace including I2C + INT. I believe I have sufficient protection, but I will double check in the I2C driver as well. Thank you very much for your time. -Katie

To follow up, in rfalNfcPollActivation we copy from nfcid1, but nfcid1 is also 0. So where should nfcid1 be set? Or rather, where in the library is the actual request to the reader to return the ID (a FIFO read)? Thanks,Katie
