Hi, I recently found this library for the ST25DV and I was wondering if anyone had an example code I could follow. I am interested in using the fast transfer mode of the ST25DV to send data from my STM32 to a phone.This is the Github library: https:/...
Hello,I've been trying several distributors but as of today I can't find one that can provide the new ST25TA-E NFC tag.Here is the tag I am talking about:https://www.st.com/content/st_com/en/campaigns/luxury-brands-security-st25tae-z21.htmlPlease can...
When I try to add the STEVAL-SMARTAG2 as a device to the ST Asset Tracker app, nothing happens. It detects the NFC, yet no ID is registered. Must I activate the NFC before?Edit: I tried the steps (see below) in the manual to enable the UART by removi...
I followed the user manual and loaded the examples as it is, however, I didn't get any sensor data return as expected, any possible reason or steps I may have missed? This is the user manual expected output Where as this is my resultWould appreciate...
Hi,We are planning to use ST part# ST25R3916B in one of our projects. The product is targeted for European market, and it might also be targeted to US and other global markets as well. Could you help us to know the various design aspects (Electrical ...
Hello,i'm working on implementing a system using ST25DV64KC Dynamic Tag with an NFC Reader.Here is a summary of my current situation and issues:1. Current Setup:- I've successfully tested ST25DV Tag using the NFC07A1 board- I'm now transitioning to u...
Hi,I'm working with the NUCLEO-NFC07A1 (that mounts ST25DV64KC chip), and I'm trying to read the dynamic registers via the I2C interface. However i've some problems reading the IT_STS_Dyn register at 0x2005 addr.This register should indicates which e...
你好我正在使用 NFC08A1 Nucleo 扩展板。我正在尝试通过 SPI 将此板与另一个 renesas 微控制器连接。我已经通过 SPI 线、IRQ 和 GND、VCC 上的跳线连接了扩展板。我正在将 RFAL 堆栈用于 3916B IC。此时，程序初始化 （demoIni（）） 已经完成，进入 demoCycle（）;我发现 rfalSetAnalogConfig（（RFAL_ANALOG_CONFIG_POLL |RFAL_ANALOG_CONFIG_TECH_NFCV |RFAL_A...
The ST25DV and M24LR define custom commands for specific purposes. Is there a way to override these command values so I can send a small few byte payload over NFC to the chip, read the payload, and send back a response with the same command value?Th...
Hi,I have been working with the st25r3916 in my reader. My idea is to use a mobile to communicate with the reader in card emulation mode. I have been using the demo code for st (ST25NFCEmbeddedLibSrc_ST25R3916(B)_1.6.0).With IOS it is working fine, a...
