Hello There,I am currently trying to use the ST25R200 with the X-CUBE-NFC10 Software package.First thing am not sure about: In the "Software Packs Component Selector" I have to configure the "Board Extension NFC/NFC10A1" even when i don't plan to use...
Hello, I'm updating an ST25R3916B project to use the ST25R300 due to the obsolescence of the Murata variable capacitor. This project is read/write of ISO15693 tags only, no card emulation or anything fancy. It uses one IC which is then multiplexed ...
Hello,I am a French engineering student working on a startup project as part of my MBA. We are developing an interactive musical box for children aged 3 to 7 years old.The core feature of the product relies on RFID detection: small figurines shaped l...
I want to try the multi antena design mentioned in AN6121. where can I either download the gerber files for the PCB or order a PCB?
Dear ST colleagues,I tried recently the package X-CUBE-NFC12.First I tested on NUCLEO-L476RG board the delivered example and it was working out of the box, then I tried on NUCLEO-C071RB but it was not working, first I noticed that the Pins configurat...
I am currently working with the X-NUCLEO-NFC10A1 board and interfacing it with an ESP32 DevKit V1. While attempting to establish communication between the two, I have tried all SPI modes as well as different reset logic configurations, but I am still...
Hi all! I'm trying to implement a wear leveling in user memory accessed from I2C for a counter on bit level. My question is: Are ST25DV eeprom byte cells similar to classic ones where each write cycle starts with a clear (which sets the byte to 0xFF)...
I have been using RFAL succesfully with STM32L4. For a more price sensitive project I need to port the code to STMG070 and I cannot get RFID readings to work. Measuring ampltiude gives same result on both codes:st25r3911MeasureAmplitude(&c); printf("...
Just a heads-up, this post was written by AI. I used it to document a process of debugging this board, and create a summary for a forum post.Platform: ST25R3911B, RFAL library, ISO 14443AConfig: Single-ended mode, 0.3m 50Ω coaxial cable, remote anten...
Hello, we have a working design that is in production, but obviously cannot keep building because of the EOL variable capacitors. Our application is reader only, no card emulation. Since we don't need CE, do the variable capacitors need to be populat...
