Hello,I'm trying to communicate to ST NFC IC ST25r3914 with another mcu through SPI communication. I have successfully initialised NFC IC but I am getting NFC IRQ interrupt only four times. After this control comes only till RFAL_NFC_STATE.
Can X-NUCLEO-NFC06A1 module be connected to a raspberry pi without ARPI600 raspberry pi to Arduino adapter? If not, which Arduino is recommended to run the module?
Which ST25R reader would you recommend for the MB89R118C Fujitsu Tag which has FRAM of 256 memory blocks/ 2048 bytes and uses ISO/IEC15693? For some reasons I could not write or read from this NFC type 5 tag with the NFC Tap app? Please advise.
The "AN5276" application note says we should measure the antenna at 1MHz.I don't understand why we couldn't measure it directly at 13.56MHz.
Hi,I'd like to integrate calypso protocol (Calypso Networks Association) in a terminal based on STM32 + ST25R3911.The STM32 will run a SW package which implements Calypso (taken from https://keyple.org/learn/build-your-first-app/cpp-app/).My question...
No example of analog M1 was found in the provided routines，Can you provide technical support for this ?
We are trying to interface ST25R3914/5 NFC reader IC with another microcontroller through SPI communication. But while the ST NFC reader IC is not able to detect the card.Can you please tell what all steps are to be considered before interfacing NFC ...
Hello,I'm new to RFID and I have troubles with the RATS command of the ISO-14443 standard. I am currently working with a CR95HF (reader) and a ST25TA02KB-D (tag). The uC driving the reader is an Arduino UNO, this part is working fine so far.My issue ...
After writing a NDEF message to the M24SR02-Y NFC Tag the Chip doesn't work anymore. If I scan it with a NFC app I can see that under technologies NDEF isn't listed anymore. Before the writing process it was listed. Does anybody know a reason for thi...
