hello everyoneI am using st25ru3993.The features we want are:1. Is it possible to split the frequency down to 0.1 MHz?2. Is it possible to split the db by 0.5 or 0.1?3. I am testing the sdk and I want to check the dbm value. What class or structure c...
I want to implement writing of data on password-protected NFC 25 tag) ST25DV04KIn my case, I have enabled write protection on Area1 with password 1 set using the NFC tap App.I want to use a known password to enable my Android and iOS to write the dat...
Hi everyone ! After successfully launched ST25R3911 (in 14443-A smart card reader mode) without RFAL , using only analysis of dialog on ST25R3911B-DISCO there was a need to implement an 14443-A emulator based on ST25R3916. With the DISCO everything i...
Hello, I am working on ST25RU3993 STUHFL SDK package v3.1.0.0 to run the STUHFL_demo applications on a Raspberry Pi 3 Model B V1.2 device. Following the instructions specified in the user manual (UM2618), I compiled the middleware source files on RP...
We are trying to interface ANT7-T-ST25DV04K and CMWX1ZZABZ-078 (MuRata LoRaWAN module that has STM32L0). When we read the NFC chip using I2C by the host processor STM32L0 (in LoRaWAN Module), we are reading garbage data (corrupted). However if we use...
I am trying to develop an application in C/C++ (QT) to perform an ISO 15693 R2H FTM data transfer with an STDV04 tag using the STR25R3111DISCOComm DLL. I am able to link to the DLL, connect to the DISCO board and perform a passive read on my tag usin...
Lets start with what works... I can write NDEF payload to ST25DV via I2C and read it back via I2C and using NFC Tools App.... This works fine and perfectly. I can also write NDEF messages using NFC Tools, and read back what I wrote no problem. The ex...
hello stI am using ST25RU3993-HPEV now, now I want to use UART to communicate with the host, please tell me the detailed operation steps, thank you!Second, if I want to reduce the communication rate (3M), such as using 115200, what should I do?
Hello,I have it working on a Arduino with ST25DVK, know ihave trouble switching from a ST25DVK to a ST25DVKC, I can see the i2c is never established, I was wondering since the ST25DVKC has a configurable slave-adr, that I then have to set it myself.
Hello!I am new to ST products and have recently ordered ST25RU3993 reader IC evaluation board. The idea is to use the reader for access control in a building. I was wondering if any electrical motor driver could be connected to the evaluation board?T...
