I am looking for an HF reader board to which I can connect an external antenna. I own the STEVAL-253916B and it might be possible to modify it to accomplish this but I can't locate the Gerber files on the ST website to make sure I'm doing it correct...
HelloWe are currently using ST25DV64KC nfc-v tags in our products, and found a possible bug during production.We set the NFC password in the last production step, using a self-developed android app (as, to my uderstanding, it cannot be done via i2C),...
Hello everyone,I am using an NFC08A1 for my project and I would like to use the AAT. I roughly understand what happens in the AAT algorithm. However, I don't get any noticeable improvement when I apply it. The range in particular remains almost the s...
I am using the ST25R3918 and the 'pollingTagDetect' example from the RFAL library. This chip does not have the ST25R3916_CMD_TEST_ACCESS register.How can I modify this library?
Hello everyone,I'm trying to compile the code wich is give at this address on STM32CubeIDE and I have some problems when I want to compile the code. CubeIDE choose automaticalement the wrong "stm32l4xx_hal.h" and don't bring the one wich is in my wo...
On both boards the demo application is installed, Oneshot on the STEVAL-SMARTAG2 and PollingTagDetect on the X-NUCLEO-NFC03A1. When using the STEVAL-SMARTAG2 without battery it can be read however I always see the same sensor data. On the debug port...
Hello everyone, for my project, I need to read a tag in two different places. Currently I am using an X-Nucleo-NFC08A1. I would like to add an additional X-Nucleo-NFC08A1 reader.The communication is done via SPI. What adjustments do I have to make in...
Hi,My application used ST25R3916B for transmit power for the card only.1. Is it possible to leave the EXT_LM pin unused or exclude external load modulation from my application?2. Can I use the testing point only on the pin EXT_LM pin?Best,Dalik LIM
1. NFC ST25R95 Can I process if I don't use the MCU to control?2. Can I boot up voltage to 10V for pin TX1 and TX2 for differential pair?Best,Dalik
Hello, I want to perform data read/write operations using NFC. However, I have some concerns due to NFC standards. ST25DV64KC and PN5180 module both adhere to the ISO 15693 standard. Has anyone previously done read/write operations using the C langua...
