Hi, I am trying to understand the difference between blocking/non-blocking rfal apis. ReturnCode rfalNfcvPollerReadMultipleBlocks( uint8_t flags, const uint8_t* uid, uint8_t firstBlockNum, uint8_t numOfBlocks, uint8_t* rxBuf, uint16_t rxBufLen, uint...
Hello community,I'm developing a FW for a board that uses the ST25DVxxxKC to show some board info (as tags) and to allow to update the FW.I've no problem or doubt on the board side (FW).I'm trying also to develop an application on a PC equipped with ...
I have purchased X-NUCLEO-NFC03A1 (CR95HF) evalboard, and nucelo-F072RB board.I want to develop RFID reader/writer . Please suggest a firmware example code which I can program in the eval board. Secondly Does ST has any PC based utility which can be ...
Hi Sir/Madam, I am working with I2C in x-nucleo-nfc07a1 where ST25DV IC incorporated interfaced with Nucleo-WB55 board, what is the slave address(device address) for this?I am firmware engineer, I have I2C Scanning program wherePreviously, I work wit...
Currently, I'm using CR95HF on our product which went into mass production already. The tag is small with diameter only 9mm. In the field, we are seeing a few percentage of unsuccessful read from the first read and need to retry several times. How...
Hi,It may be a *** question but, im quite sure i read time ago that on VDD_AM pin the 2u2 cap must not be place at one sccenario, but now im not able to find where i read that info and also i dont remember which was the scenario. I start to think im ...
Hello,I am trying to port/get running the NFC08A1 RFAL polling demo on the NUCLEO-F072B. I had no issues using L476RG. I am fairly certain I have SPI set up correctly in CubeMX. But, I am getting stuck at initialization, specifically at st25r3916C...
I'm working on implementing STEVAL-ST25R3916B reader expansion board circuit schematic into custom PCB. Can I please get the actual design files for these, including the layout. I did find the pdf version but it would be great to have the design file...
I have a product already developed using the M24LR64ER and I need to read and write using an IPhone 14 with IOS 17, would it be possible to read and write using Swift's "import CoreNFC"?
I am in the final stretch of my project using the ST25R95 with an ATTINY88. I am working on custom hardware and not using libraries.I have all of the ST25R95 related commands working on my development setup with an Arduino UNO and X-NUCLEO-NFC03A1 b...
