Hello,I'm designing a battery powered device with integrated payment terminal. The goal is to pass EMV Level 1 certification.Our approach is very bare metal. We design the board, circuitry and firmware from scratch. No HAL or RFAL is being used. Our ...
I'm trying to change from ST25DV16K board to ST25DV64KC and use it.The board setup part seems to be fine, but there's a problem with the interrupt setup part.When writing data to the EEPROM of the tag board with RF from NFC08A1, the code that worked ...
Hello,I am working on a project where I need to read the UID of an NFC tag using the ST25R3916 and communicate via I2C. After powering on, I can successfully read single register, but after setting the device to "Ready mode" by setting bit 7 of the O...
I'm working with the STEVAL-25R200SAand trying to implement Transparent Mode to directly receive raw data from the MISO line. I've followed the datasheet and configured everything as per the documentation, but I'm still not receiving any data.Setup a...
This seems like an "easy" topic, yet I'm struggling to get a clear understanding.Section 3.2 of the datasheet (Operating Conditions) defines a single, wide range for VDD (2.4V to 5.5V). But Section 1.3.2 (IO Configuration Register 2) defines two non...
Hi Community,We are currently developing an NFC reader for our access control system that needs to read NFC passes stored in Google Wallet and Apple Wallet. The system should: Read emulated NFC tags from both Android and iOS devicesExtract the NDEF p...
We are considering transferring power along with NFC communication using the ST25R3916 chip.From one of the application notes, we found the following block diagram, as shown in the image below. According to the diagram, the power amplifier is placed ...
Hi,About rfalST25xVPollerFastReadMultipleBlocks and rfalNfcvPollerReadMultipleBlocks。I use st25r3916 to read NFCV tag.The farthest reading distance of my reader can reach 70mm.When I use the command RFALNFCVPoller Read Multipleblocks, I can successfu...
Hello everyone,As a students at a company do I try to build a tool or method to evaluate some parameters of NFC coils (Q and L). I have been given some NFC tags to proof the correct functionality later. One of those tags is the "ANT7-T-ST25DV04K" wit...
Hello!Is there any additional information about on how to use on ST25R3916 the bypass mode of internal VDD_RF regulator to be able to a transmitter output current higher than 350 mA (up to 500 mA) supplied from an external source.In ST25R3916 datashe...
