Hello all,I am trying to read NFC Type V (ISO15693) tags using an ST25R200 and an ESP32-S3. For this purpose, I am using the ST25R200 evaluation kit and have connected the ESP32-S3 by soldering enamelled copper wires to the exposed pads on the develo...
Hello,I am designing an NFC reader based on the ST25R95 transceiver and I would like to use the ST online NFC Tuning Circuit / Antenna Matching Tool to calculate the antenna matching network.However, I cannot find the ST25R95 among the selectable ICs...
Hello, i need help for an issue with HLTA command.I'm working with ST25R100 and I'm writing code direclty in uP without RFAL library. I finished writing anticollision routine and it works fine, but when I try to put PICC in HALT mode it continues to ...
Hi STM teams , i have developed a custom NFC board using the STM32L476RCT6 and the ST25R3916B NFC reader, based on the reference design of STEVAL-D25R16B (https://www.st.com/resource/en/schematic_pack/steval-25r3916b-schematic.pdf). I am using an ext...
Hello,I start testing with the STEVAL-M25R16B Board and use this Time the self compiled Demo from ST to test it. All works find.Then i made an own PCB with Reader IC and Antenna on it and connect it to your MCU /Display Board.The Board is connected ...
