Hello everyone, in a project we are using the ST25R3916 chip to read RFID cards. To do this we are using the sources of the STSW-ST25R-LIB library. If the ST25R3916 sets its IRQ output, the routine st25r3916isr() is called. In this ISR the interrupt ...
Hi,Is there any NFC chip that is capable of emulation NFC-V Tags (ISO 15693)?Thanks.
I am designing a custom board using your ST25R95 chip. To design the matching network given the antenna parameters, which I show in the following picture: The tool you recommend (ST25R95_EMI_FILTER_CALCULATION) for the matching network returns me ...
Hello, I’m working on a project with an X-NUCLEO-NFC08A1 board to use it as an NFC Reader. Specifically, I have an NFC TAG, and I want to use the NFC08A1 board to read and write to this TAG.I’m currently looking for some example code to help me use t...
I'm working on emulating a T2T with my device. It successfully makes it through automatic anticollision, then starts looking for commands. When I see 0x30 0x00, I go ahead and send the first 16 bytes, but the reader does not react or show the read da...
We use STM32F103C8T6 as the main control chip, ST25DV64KC to do the slave and ST25R3911B NFC communication project process, we found that we are very confused about the initialization of ANT7-T-ST25DV64KC, we have been initializing failure in the pro...
I am working with the ST25DV tags. I have generated a capability container, TLV Header and Terminator and construct a well-formed NDEF message with 5 records. I am able to read/write single/multiple blocks and perform most actions that i need in in...
Hi ST team, We are going to use the ST25R3916B chip in our project to design NFC reader. Due to mechanical design constraints, I have to place the antenna in separate PCBA near NFC tag. I would like to know how should i connect my RF output from read...
Hi,I am using the ST25R3916 (NFC06A1 board) to perform NFC read/write operations with passive tags and Android-based devices (essentially used as passive tags without any background apps). Recently, I tried to use an iPhone, but I can't get it to wor...
我目前正在从事一个需要使用 STM32F103C8T6 微控制器和标准库进行代码编写的项目。在此过程中，我遇到了 ANT7-T-ST25DV64KC 芯片初始化的问题，一直卡在“while （！I2C_CheckEvent（I2C2， I2C_EVENT_MASTER_MODE_SELECT））;在此步骤中，我还对读取 I2C_SS0_Dyn 数据感到困惑。读出的数据永远是我在 read 函数中写的 slave 地址，有时读出的数据会增加 1。这是我的代码 无效 ST25DV_Init（void...
