Ask questions and find answers on ST25 NFC/RFID tags and readers, including connectivity implementations and antenna design.
Dear Sir,When I read 2.2.4 in the datasheet, there is a Note asUsing hardware based wake-up in combination with the automatic antenna tuning feature isnot recommended. Contact your nearest ST office for further support.Could you tell me where I can f...
I'm trying to port the NFC-RFAL library to a smaller Arduino based MCU. I need an extremely minimal setup for retrieving UIDs from ISO15693 tags, so I'm getting rid of 50-80% of the state machines and structures, the whole analogConfig module, maybe ...
We are developing RFID reader with ST25R3916. As design reference and parts selection, I wonder if we can get the schematic and BOM of ST25R3916-EMVCO. best regardsDai Sai
Hi all,I'm trying to read and write values to an STmicro tag(ST25TA02KB-D, ISO 14443-4) using the X-Nucleo board from a python program. I've tried a number of approaches(waveshare pi hat, standalone PN532 modules, using libnfc and adafruit libraries...
I tried to build the NFC Tap app in iOS, but was not able to compile.I added the J2ObjC paths.The problem is a Swift Compiler Error in the include chain, see screenshot.
Hello,I have a nucleo-nfc06a1 board that I would like to use for wireless charging and communications to a st25dvi2c tag. On the tag side, I have a rectifier bridge that supplies a battery charger. The resonant frequency of the tag antenna has been s...
Hello,I have a problem with the ST25DV04KC-IE.In the datasheet the register MB_WDG (000Eh) must have a factory value of 0x03 but my chips have 0x1a. Bits 3-7 are RFU in the datasheet. Do you know why there is a difference?The real problem is that I t...
Hello,We currently have a desktop application based on C# for communicating between ST25R3911B-DISCO board and ST25DV dynamic tag. The application itself is similar to ST PC software for ST25R3911B-DISCO board but with limited functionalities as cu...
I am using ST25DV. Access from RF must be restricted.I'm trying to use RFSwitchOff / RFSwitchOn for this purpose, but NACK is returned.Before using these, I changed the I2C_CFG setting in the System register to 0x3A (I2C_DEVICE_CODE: 1010, I2C_E0: 1,...
Hello,I am currently interfacing ST25DV with STM32L073 MCU using lower level drivers for I2C instead of HAL drivers. I have successfully configured and tested the ST25DV FTM mode.Now i want to use the user memory region in ST25DV to store product inf...
