Hi, Im developing an app that use more than one ST25R3911B-Disco reader boards at the same time and I need a way to differentiate between them. As such, does anyone know if I can use any of the command provided by "ST25R3911_Interface.cs" file and if...
Hello Folks, We intermittently see an "invalid protocol - 0x83' error while reading data.send_cmd 0x04 0x04 0x16 0x00 0x00 0x00rcv_hdr 0x83 0x00This happens intermittently and I have not been successful in reproducing the error. Usually a restart or ...
We would like to use the ST25RU3993 in device side usage as described in the ST UHF library manual. Therefore we installed the STSW-ST25RU-SDK Firmware and build it with the TRUE STUDIO. Unfortunatly the given function docycleinventory does not show ...
I am writing in reference to RFID tag reader project that we are working on it. We have studied it and this gives us insight how GUI is working and how data is flowing from GUI to RFID pcb.Inspired from your GUI software we are trying to develop our...
I use passive RFID tag with NFC03A1 card reader, I have create a little program to detect RFID tag, the range is up to 5 centimeters. Is there a way or a configuration to increase this range ?Thank you in advance.
I'm using the demo code ST25R3911B-DISCO, and I don't find how are making the request for other board by RFID, I want to know if the code using interrupts to make this request each time gap or if this code makes a request just when calling a function...
I using in my project today the ISO 14443 Protocol, but I Will need to arrive at the highest transmission rate, I believe that ISO14443-4 could give me that rate.Is it possible to implement ISO14443-4 in ST25R3911? What is the function that I can use...
I am using ST25RU3993-HPEV. I have tested with GUI application on USB and it is working. Now I want to run HOST application on UART so what changes needs to be done on EVAL to connect on UART and which UART should use?
In one of the projects I am working on, we need to develop an RFID reader tester. I was hoping can we use ST25RU3993 for sweeping from 800MHz to 1000MHz. If yes are we supposed to just change the VCO & PLL block register the contents.
we recently bought a M24LR-DISCOVERY evaluation kit.I can able to write and read using ST25 app.For our application we have to develop our our own app. For that i need NFC read & write command code format from ST25 app to M24LR-DISCOVERY.When i try t...
