Hi,I am reading mifare desfire tag which is iso14443-4 compliant using cr95hf.Most of the time, communication is completed successfully but sometime, i am getting 0x90 result code when using SendRecv command.0x90 EUnintByte Residual bits in last byte...
Hello,I am working with an NFC reader with an ST25R3911B chip. The problem I am experiencing is the output power. The power emitted by the antenna is too high; therefore, my task is to reduce the transmitted power.To do this I have relied on reading ...
As written in the title, the ST25PC-NFC software does not detect the STEVAL-25R3916BA reader, despite being in the list of compatible readers. What can I do?Thank you
Hello,I added the RFAL software library to my existing wireless charger project.When I set totalDuration to 50U, there are cases where it cannot detect the card. I get better results when I set totalDuration to 25U. Will it cause problems if I reduce...
Hi,I have a X-NUCLEO-NFC08A1 and trying to use ST25R3916B RFAL library with nRF5340 from nordic semiconductor. SPI communication and initialization are working. I am running demoCycle() function from demo_polling.c. However, in the logs, I receive a...
Hey All, I'm looking to bootstrap a custom NFC antenna and was wondering if anyone could point me in the right direction for how to attach a ST NFC chip to a silver nanoparticle printed antenna using a laser jet (with this ink). Someone suggested us...
Hi ST Micro Team. We are planning to start a pilot project on the use of RFID in our office, We want to to place the tags on the laptops so that whenever an engineer with laptop exits a room the reader should detect. Could you please suggest a possi...
hello, I'm working on ST25DV64KC, especially on FTM mailbox function and EH power supply. Current situation is I need to test maxium frequency avaliable for supplied by EH(STM32L476VGT6 with ST25DV64KC) while communicating through mailbox(FTM). The ...
Hello,I'm trying to use the ST25 java SDK. The software_guide pdf document says I need to load in my IDE the natives libraries the SDK will need. It says I will find them in t \readers\st\resources, but in this folders there is only windows/x86 for t...
Is it possible to adjust the slew rate of the RFO1/RFO2 outputs of the ST25R3916B?
