Posted on September 06, 2016 at 02:03Hello, I am interested in using the M24LR64E-R in an application very similar to STEVAL-IPR002V2. Is the firmware available to download for this evaluation module? -Mike #m24lr64e-r
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...
