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...
I've been reading through the Wake-Up Mode and Automatic Antenna Tuning application notes, and while I understand that AAT and Wake-Up with inductive sensing require more involved software wake-up logic, it doesn't seem to me that capacitive sensing ...
After reading the data through the ios NFC Tap app, the Linux platform can't read or write data to the ST25DV64KC through the iic.Below is a log of the app after it was read and operated with linuxBelow is the log that is not read with the app and op...
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 ...
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 ...
I have two Nucleo boards, both NUCLEO-L476RG. The first board is equipped with the X-NUCLEO-NFC08A1 (ST25R3916B), while the second board has the NFC 5 Click board (ST25R3918).I am trying to establish peer-to-peer (P2P) communication between these boa...
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...
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...
