Hi Ulysses, Thank you for your response... I understand that the ST25R3916B doesn't send frames autonomously. From what I've read in the datasheet, it seems that this chip can generate an RF field (in response to commands sent via the micro through S...

Hi Brian!Thanks for your response. I performed additional checks with the oscilloscope on all signals (MISO and MOSI), and they appeared correct. However, I was still experiencing issues with reading and writing registers via SPI.I made some changes ...

Hi Ulysses!The problem has been resolved. Checking the MISO, MOSI and CD lines again with the oscilloscope I realized that the CS was not working correctly. In fact, I noticed that in the microcontroller I use (STM32U575), the pins of the CN5 are not...

Hi Ulysses!!I'm trying to understand the ndef_rw example, but I'm encountering some difficulties. Especially, there are a few points where I need clarification:Which mode should I enable to work with ISO 15693? I noticed that the example is based on ...

Hi Ulysses!Thank you for your response.I know that the management of messages and NFC protocol details is the responsibility of the micro, but this isn't the issue that i'm facing. I've successfully used the ST25DV64KC chip as tag, interacting with i...
