Hi,I go my own hardware, that connects the ST25R3916b-aq chip to a nRF52840 Bluetooth Module and its SPI bus. (and the I2C bus, just in case).Im using the Segger Embedded Studio with the nRF5 SDK for programming.Because and the communication is quit...
Hello,I am designing a system that uses the ST25R3920. I am using the STSW-ST25RFAL002 software library to interface to the NFC reader.For performance & power saving reasons, I am attempting to complete NFC transactions as quickly as possible, and tu...
Hi, It looks like the kill command is not working for ST25TV16K. I am getting an error command as shown below:The register values are given below:
I am attempting to create an NFC antenna for the M24LR04E-R chip, following the circuit diagram of the x-nucleo-nfc02a1 board. My challenge is that the x-nucleo-nfc02a1 board uses a double-sided antenna, but I want to design a single-sided antenna th...
Hello community,I´m trying to use LL driver for the communication with ST25DV64KC chip, the register address of this chip is 16bits, but the current LL driver only supports 8bit, I tried to adjust it and failed. Do you have some LL driver examples f...
Using st25DV tag on our embedded system. In short, the second I2c read does not display the same data that was written. It differs, as the first byte changes to 0xFF. When I write to the mailbox the first time, and then read the data, it's the same. ...
Hi,I want to know if there is a provision to lock an entire area in ST25TV tags. I can see from the datasheet that blocks 0 and 1 can be locked, but I cannot see anything for other blocks. I know that I can use a password to do same but I do not want...
I'm tring to detect tag infomation by ST25R95.Main board is STM32L476RG.I got the sample code from https://www.st.com/en/embedded-software/x-cube-nfc3.html.Example commands are descripted in the datasheet https://www.st.com/resource/en/datasheet/st25...
Hello all,I'm currently working on a project to detect multiple objects on a grid. I plan to put NFC tags on each object and use only one reader to detect all of them. One of the solution is to have one reader's antenna per cells.Is it possible for m...
How can I power the STM32L476RG board via the EH pin of the ST25DV? Is there a module for this?
