ST25 NFC/RFID tags and readers

Resolved! Information about the possibility to upgrade Firmware on STM32

I have heard the ST25DV can be used to upgrade the Firmware of any STM32 Microcontroller. I would like to understand how this is done. Also how the PINs needs to be connected to the STM32. Or is the code transfered via I2C? If so, how does the STM32 ...

Resolved! I am having difficulty reading tags

Hi,I’m trying to use the CR95HF in what I think should be the simplest mode. Reading a 14443a tag.I am controlling it from a pic micro. I have detailed exactly what I have done. Clearly the SPI is working but I am also missing something. Really appre...

Resolved! Hi , is there any android support .? for ST25RU3993 kit

Resolved! Can't make ST25R95 example to work in my MCU

Hello guysI'm using the STM32F070CB MCU in a custom board connecting SPI pins and IRQ pins to the MCU and trying to scan for NFC devices. We've tested the board and the ST25R95 with std32duino libraries and we could make it work, but we needed to see...

Resolved! Looking for smart cards working on different standards. Anybody have an idea where can I find those?

I have been working on a project with CR95HF multi-protocol transceiver IC. The obvious advantage of it is that it can read tags working with different protocols (different standards). I already coded so the IC reads different standards according to ...

Resolved! ST25DV64K-IER6S3 load on I2C bus with VCC = 0

Hi thereIt seems that ST25DV64K-IER6S3 does not load the I2C bus even when there is no power on VCC. I have checked the datasheet but I have not found any information on that.Could you confirm it?BRGilberto

Resolved! ST25DV64K-IER6S3 - GPO Operation (open drain)

HiI am trying to obtain the smallest possible power consumption with an ST25DV64K-IER6S3 device. I am wondering is the GPO pin is still operational when VCC is removed? Is it the GPO circuit powered by the RF interface?Best RegardsGilberto

Resolved! what to do when you want to password protected write for nfc 5 tag using st25dvXX ?

I am implementing nfc reader and writer application. i am able to write in a tag. But I want password authentication before write what i should do to achieve this.Thanks st community for your Helpful information.

Resolved! Development Kits antenna considerations

Hi,I've noticed that the pcb antenna (ANT300) on ST25R3916-DISCO has the 3rd pin unconnected. The X-NUCLEO-NFC06A1 has this 3rd pin tied to GND. On the other hand, an identical antenna (same dimension and turns that previous one) on X-NUCLEO-NFC05A1 ...

Resolved! Control Impedance trace transmitter and receiver to connector antenna.

Hi everybody, I use chip set ST25R3912-AWLT for NFC design,In PCB layout, i was draw ST25R3912 in main circuit and connect Tx, Rx to antenna use connector.Do i need control impedance trace transmitter and receiver. Thank you,AnhDN
