Resolved! st25r3911b RX failed in FIFO reading

Hi,​I'm surveying st25r3911b now. Currently, I have verified SPI, register read/write, IRQ handler, TX process, but not RX process.So far, I can get the necessary IRQ, but I can't get the correct data in FIFO.​I make the following steps to test RX pr...

Resolved! hi there, need the c code to use UART protocol on X-NUCLEO-NFC03A1 RFID Reader with the STM32MP157-dk1 develeopment board

Resolved! ST25DV16K: Wrong data for Fast Extended Read Multiple Blocks

Hello,I' am using a ST25DV16K transponder. If a Fast Read command is executed with a block number > 255, the tag does not respond with the correct content. The tag seems to evaluate only the low byte of the address. For address 256 (0x0100) the conte...

Resolved! I am using the ST25TA64K, and I want to use the TruST25TM Digital signature Authenticity with this TAG, how can I verify the tags authenticity?

Resolved! STM32L476RG + ST25R95 : write in the NFC tag several times and put the data in the rxbuffer following without overwriting previous data.

I'm using the X-NUCLEO NFC03A1 board with the NUCLEO L476RG board. I'm testing the STM32L4xx-ST25R95-Polling software example to exchange datas between my PC and a NFC tag ( an ISO 15693 ICODE SLIX). my tag is a icode slix iso15693 so I use the demoP...

Resolved! How to use UART interface instead of SPI with X-NUCLEO-NFC03A1 and X-CUBE-NFC3 polling demo

I have the X-NUCLEO-NFC03A1 expansion board connected to the NUCLEO-F401RE, successfully running the demo polling code from X-CUBE-NFC3. I would like to modify the code to allow the two boards to communicate using UART alone (no SPI pins necessary). ...
