I would like to use ST25DV-I2C for I2C communication and GPO output.The datasheet states that to use GPO output, an external pull-up is required for the 8-pin package, and an external power supply (VDCG) is required for the 12-pin package.However, I ...
Hi everyone,I am working with the X-NUCLEO-NFC08A1, which uses the ST25R3916B chip, and I am planning to use it's main IC (ST25R3916B ) with 6 antennas. The idea is to use the two RF interfaces of the chip, with each interface connected to 3 antennas...
Hello everyone,I’m looking for recommendations on setting up an NFC system that meets the following requirements. I’m aiming to keep the project as cost-effective as possible, and I would like to utilize both NFC readers and chips. I’d appreciate any...
We programmed the ST25DV16 tag using the antenna and the GUI using the ST25R3919B. However, when we use the android apps to read the ST25DV16 tag its not getting read. The android apps read all the other tags of 13.56 mHz available in the market, but...
I'm in trouble using dll with c# for using the mailbox.Can someone help me?Please @Ulysses HERNIOSUS , my friend, help me! I'm pain too! Here is the code: private void TxRxNBytes_Click(object sender, EventArgs e) {//This is a button click event handl...
This might be *** question but I have to ask as as I'm a biginner... I want to interface ST25r3916 with STM32F072xx without using BSP package and HAL. I'm currently using bare metal embedded c. I've been trying to change rfal_Platform.h file which I ...
We are using an ST25R3916B to read and write to both ST25TV512C tags and Mifare Classic 1K cards. While we have successfully communicated with ST25 tags, we are encountering issues at the authentication stage with Mifare Classic.Steps We Are Followi...
Hi everyone,I'm working on a product that involves multiple sensors connected to a main system. Up to six sensors can be attached (see image). The overall diameter of the system (as shown in the image) is approximately 20cm. I want to use NFC tags on...
hello, im designing an RFID board, using the ST25R3918, no where in the datasheet have i been able to find what to do with BSS/MOSI (float, pull up or down). I saw that BSS is used with I2C regarding transparent mode, but that's not needed for my pro...
We are having an unusual issue where we are failing emissions at 67.8Mhz or the 5th harmonic of the NFC frequency. We are also close to the limit for the 3rd and 4th harmonic as well. It is unusual because it does not fail in all operating modes. ...
