Hey is there a Factory-Programm to upload if i mess everything up. For the ST25R3911B-DISCO board ?I want to be able to use The GUI again.
All,BackgroundChip: ST25R3914Library: RFAL for ST253911BI am currently working on a project that uses the ST25R3914 nfc chip and would like to implement the Automatic Antenna Tuning (AAT) feature. After looking at the data sheet, it states that chip ...
According to the ST25DVi2c datasheet, a high bitrate encoding has four subcarrier pulses (followed or preceded by 9.44us of unmodulated time) to designate a 0 or 1. A low bitrate uses 16 pulses and 37.76us of unmodulated time.By changing bits 3 and 4...
Hello, We are trying to make an NFC reader for door access control. Reading NFC tags and Android phones are as expected. But for Apple product we have to support Apple VAS. I found a similar question https://community.st.com/s/question/0D53W00001MY8k...
The chip type I am using is st25r3915. After I port RFAL, when I use "ST25R_SELFTEST" in "ST25NFC_EMBEDDED_LIB_ST25R3911B_1.4_0", the result of "Check IRQ Handling" is "ERR_TIMEOUT", what is the possible reason?
I want to power the ST25DV tag using a pin of the micro (VCC_EEPROM). In my idea, the micro should power it only when there has been a writing on the TAG's EEPROM. I would like to implement this by monitoring GPO, but I'm not sure if this functionali...
Hi, I've got a x-nucleo board marked shield-m24sr-adv and I'm unable to find any docs about it. Well of course its a NFC reader board but.......
After I write to the FIFO, I read the FIFO to check if the bytes were property transferred (I understand that I cannot read and then transmit, this is just for debugging). I have a strange issue where the number of bytes in the FIFO are exactly half ...
Hi there,My PhD project focuses on RFID-based wireless capacitive sensors.The Tag is M24LR04E, and I'm using a reader from the M24LR-Discovery kit with a CR95HF transceiver board and a 2 turn 424nH antenna.Current read range is 45 millimetres. My app...
