Hello everyone, I'm exploring the possibility of using NFC technology to operate and read data from a sensor equipped with an I2C ADC (Analog-Digital Converter). Specifically, I'm interested in leveraging an antenna cable or a smartphone as part of m...
Hello,I'm developing a system based on a ST25DVxxKC (tag side) and a ST25R3916B (reader side) and I need to use the FTM feature. This is what I'm currently testing:- The reader detects the tag. (That part works fine.)- When detected, the reader sends...
Hi, I am running ST25R100 on a different processor and coding it at the register level. With the codes I shared below, I was able to run the chip in wakeup mode as I wanted and ensure that an interrupt occurs when the card is approached. However, I c...
Hi ST membersI am using the ST25R95, following the application note and matching tool to define LC components for EMC filter and matching circuit. the function test is good, but I have a high pulse at 3rd harmonics 40.8MHz and 7th 94.92MHz, do you ha...
Hello ST Community,I'm currently trying to implement a simple function: turning the RF field ON and OFF for a desired duration using the X-NUCLEO-NFC08A1 board.Here is my current setup and progress:I’m using the STM32F401RE Nucleo board as the host ...
Hello ST Community,I found this forum and the example code to our custom hardware very helpful and are successfully reading both NFC-A/NFC-V and emulating NFC-A on ST25R3918.During testing, I've noticed that NFC-V tags with NDEF messages can also tri...
Hi everyone,I'm working on writing the configuration password (PWD_CFG, 0x00) to an ST25TV02KC NFC tag using the ST25R3916B reader and the RFAL middleware (X-CUBE-NFC6). I am following the standard procedure:Open a CONFIG security session using Pres...
Hello,i'm using arduino to code a STM32C011J6M6 and I want to use the Energy harvesting pin of ST25DV04K to source the IC when the VCC be off and the NFC Field be on.But with this code the EH is on just when VCC and NFC Field are on.if I remove all t...
Hello, I have x nucleo 09a1 and I managed to run it in wake up mode with a different processor than stm and register. But there is a high current in wake up mode and power down mode. I am sharing the relevant graphics and code, please help.
