Setup in use:P-NUCLEO-STM32WB development board.X-NUCLEO-NFC04A1 expansion board with software pack ( NFC 4.2.05) Added : DMA support for I2C , .ioc cubeMX image attached.The issue is that I cannot read the ST25DV ID via I2C DMA read. I simply do not...
Hello Can NFC tag be used to transmit audioif yes , which type can be used from ST and what reader would be appropriate.not the physical proximity tags but other thanks
Hello, sorry for the inconvenience but I really can't understand why I can't write/read new cards (the ones he has work) from my customer reader. What am I doing wrong?I enclose the photos, his card (working and writable / readable) and the one I cre...
We have used your ST25 NFC Tap app to read NFC tags emitted by a device with an ST25 chip. That has worked quite well up to a point when certain smartphones got their Android 12 update. Now the app displays an error.The phones are a minority but they...
In the app note an4974, ST recommends a matching impedance of around 16-20 Ohms, this part is reasonable and makes complete sense. In my configuration, I'm using differential with AAT. According to the app note, the target impedance should be at the...
Hardware:Im using SP1 of the STM32L476RET:SPI1_MOSI -> PA7SPI1_MISO -> PA6SPI1_SCK -> PA5SPI_CS ->PB6and Ext Interrupt:IRQ_3911 -> PA0my LEDs on:LED_A -> PB0LED_B -> PA4LED_F -> PA1LED_V -> PAB4LED_AP2P -> PB5LED_Tx -> PA8
The details on transparent mode are fairly lacking in the datasheet. I've found in another thread a few years ago a comment by Ulysses HERNIOSUS which revealed a bunch of extra info (Transparent mode (similar as in ST25R3911B) allows to have all nece...
Currently I am using the ST25R3911 Dev kit as a reference schematic but that IC seems to extra features compared to the ST25R95. Can I just ignore the trim capacitors and treat the RFO and RFI as Tx and Rx?Is there a better app note / dev kit I shoul...
Hi,I am interested in a device that can do both, read and be read.
Hi,Could anyone help us find the right NFC IC for our application?Our team is developing a FIDO2 authenticator that should support the CTAP 2.0 NFC transport binding found in the CTAP 2.0 January 30 specification (I'm not allowed to post links as a n...
