HelloI'm trying to setup i2c communication from our microcontroller atxmega128a1u to the st25dv64kc.I've been trying to set it up via a twi interface of the microcontroller and no matter what command I send to the s25dv I always get a NoAcK response....
Hi,i want to use the I2C Communication between the X-NUCLEO-NFC08A1 and the NUCLEO F401RE.My Problem is that i don´t know what i have to change on the X-NUCLEO-NFC08A1, because there is default SPI communication.Should i only add the resistors for th...
Hello,Using the X-NUCLEO-NFC03A1 module and ST25DV02K-W1R8S3 or M24SR64-YMN6T/2' IC. I want to do block reading and block writing. Is there a middleware and software package that supports X-NUCLEO-NFC03A1 like x-cube-nfc4, x-cube-nfc6 and x-cube-nfc7...
How can i use the ST25R3911B-DISCO without the GUI of ST? Maybe with the help of the Framework, but how can I use the code or is there any documentation, because i can not found any.
Hello everyone! I have difficulties to run the 2.8.0 Linux Demo (the latest one) the X-NUCLEO-NFC08A1 with the ST25R3916B on Linux/Raspberry both with SPI as well as the less oftendused I2C. I don't have the interface board "ARPI600" to interface the...
Hi,I am looking for an appropriate RFID reader IC for reading multiple tags simultaneously. The reader should be able to read 50-300 RFID stickers attached to packages stored in a container. Also the reader should cover a distance of 1m - 3m. Is ther...
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?
