Posted on October 16, 2017 at 11:54Dear community,is there an embedded software available (for STM32L476 or similar microcontrollers) which shows how to read a passive type 4B tag (ISO14443B) with the ST25R3911B reader? I was working on a device wit...
Posted on September 26, 2017 at 09:23I use a CR95HF with UART communication. I make the startup sequence with t0= 200 us. I have 30 boards with CR95HF. One of them don't communicate with my microcontrolleur. I change t0 = 250 ms and after this opera...
Posted on August 11, 2017 at 11:26Hi,is there a way to detect if a tag ISO14443A/B leave the field of CR95HF antenna? I need to detect the event 'card removed' without change status of the card , therefore I can't send any messages to the card.Best ...
Posted on April 02, 2015 at 06:35I am trying to use the CR95HF to read mifare classic tags. I am trying to send the authentication with key a command. I have been monitoring the communications between the CR95HF and the card using a proxmark. I am c...
Posted on September 21, 2017 at 16:40Hello,I am working on Project which have ST25TA02K-PC6H5 as a portion. I am seeing that interface between MCU and the NFC is the GPIO pin only.Neither have I2C nor SPI. With the GPIO pin, How can I read/write th...

Posted on September 14, 2017 at 09:00Hello,I got stuck while trying to make changes in code of ST25TA02K-P NFC tag for read/write access protection through password. I'm using X-NUCLEO-NFCC03A1 as reader and writter .So does ST25TA support protect...
Posted on September 13, 2017 at 01:41Our application will have two st95hf devices connected by external microcontrollers through SPI. I just need to be able to transfer data from one st95hf to another. I don't need two way communication, just one di...
Posted on September 10, 2014 at 13:02Hi,I have designed a CR95HF based Board. The circuit diagram is exactly as per the 0018253A PLUG-CR95HF-B.pdf found on the ST Website. I have tried to match the PCB layout of my board to this board as far as poss...
Posted on August 10, 2017 at 13:52ST25DV04 NFC I2C communication problem if ST25DV04 all time under Reader. There are cases (one per tens of minutes) that communication on I2C and RF is closed together and there is no way to reset if ST25DV04 to nor...
