hello, im designing an RFID board, using the ST25R3918, no where in the datasheet have i been able to find what to do with BSS/MOSI (float, pull up or down). I saw that BSS is used with I2C regarding transparent mode, but that's not needed for my pro...
Hello,I'm running a demo from STSW-ST25R-LIB which uses NFC-V. The Inventory poll returns RFAL_ERR_FRAMING as the SOF does not match. Also I have to push the tag really close to get this behaviour. The tag (M24LR64) should be fine as I can communicat...
Hi All, I'm working on implementing the fast transfer mailbox into a project and I've hitt a wall. The work-flow that I want is for my host chip to wake-up and initialize system registers and write some static data I know will never change to area1, ...
I would like to connect a 1.4uH antenna to ST25DV-I2C.The datasheet says that there is a 28.5pF capacitor inside the IC for RF interface tuning.However, when using a 1.4uH antenna, the resonant frequency shifts from 13.56MHz.How should I adjust the r...
I would like to use ST25DV-I2C for I2C communication and GPO output.The datasheet states that to use GPO output, an external pull-up is required for the 8-pin package, and an external power supply (VDCG) is required for the 12-pin package.However, I ...
我手里有 X-nucleo nfc03A1 和 nucleo f103rb。如何修改示例程序上的 uid，然后读取 HID 类卡？
I am currently using STM32U5 + ST25R3196B with STM32CubeMX and X-CUBE-NFC6.The program is based on the documentation from X-CUBE-NFC6.Previously, I tested the example on the STM32F4 series, and it worked correctly. However, after migrating to STM32U5...
Hello, I couldn't find any examples with RFAL to use capacitive sensing and the usage of AAT. I'm using a single ended matched antenna. I tried using rfalAdjustRegulators(), it always gives a value of 3000. I also wanted capacitive sensing: the chip ...
We programmed the ST25DV16 tag using the antenna and the GUI using the ST25R3919B. However, when we use the android apps to read the ST25DV16 tag its not getting read. The android apps read all the other tags of 13.56 mHz available in the market, but...
Hi guys,Can someone explain to me why there is no ESD protection for this circuit?Or is it not necessary?Thank you
