Hi there,first of all: I'm a software engineer and working with electronics only as a hobbyist. Therefore expect *** errors :)I'm trying to use a ST25R3916B in my ESP32 project. The I2C communication to the ST25R3916B is working.The call to rfalNfcIn...
Hello,I am in the process of obtaining the inventory information of ISO15693 tag using ST25R3916.But the data received seems not normal, so I want to get help.. My register settings are as followsDircet_Command(SET_Default);Register_Write(IO_configur...
Hi ST team, Can I connect an external antenna to STEVAL-25R3916B board ? In my project i need to connect the external antenna through a SAM connector cable. what changes i have to do in this board for antenna tuning and matching network?
Hello,I'm using it with a custom board. I'm facing problem with switches the ST25R95 into low power consumption modeWhen I send Calibrate command, it can work and return 0x78.But if I send another command like wake up in IRQ_IN(07 0E 08 01 00 38 00 1...
Hi, May I know the available test points on STEVAL-D25R16B for me to connect S11 of NANOVNA to ? Also, which of the register values (space a and b registers) are essential to set the board to high impedance (VNA mode) before connecting the nanovna t...
Hello Developers,In my product solution based on the STM32L496VGTX, I am currently adding NFC DFU functionality. Using the FTM Demo Feature in the ST25 NFC Tap App, we were successfully able to update and store firmware packets using the mailbox of ...
Hi,I have successfully ported the ST25R95 library from STMicroelectronics to my own microcontroller, an nRF52832. I am now trying to read the payload of an NFC-A Passive ISO-DEP device with the UID: 5F471DC2783A8E.In the polling_demo.c file, I see th...
Hello everyone,Is there an example project available to make the ST25R95 on the X-NUCLEO-NFC03A1 shield work with the NUCLEO-G071RB?
Hello everyone,I'm working with the NFC08A1 (ST25R3916) reader, and I'm encountering an issue with SPI communication when trying to read the ST25R3916 registers.I’ve written a simple function to read a register, as shown below: uint8_t Read_A_RegSp...
Hi, I'm currently examining the X-NUCLEO-NFC08A1 as a NFC chip for our project. And I've stumbled across a problem. Our own Hardware runs predominantly on 3.3V. In theory, this would not be a problem as the Chip st25r3916b supports the 3.3V operation...
