Hi there, I'm trying to emulate an ISO/IEC 14443-3 Type A card (NXP NTAG) with ST95HF. My device can now READ data by an external card reader. The anti-collision filter(ACFILTER) has enabled for ISO/IEC 14443 Type A protocol.According to the datashee...
Hi,I was able to read ISO/IEC 14443-3 Type A tag using tag_hunting function from sample code. Recently I found tag detection may help to bypass polling stage and interrupt the Host MCU if there is tag nearby. // Calibration command [07 0E 03 A2 00 F8...
I am trying to compile the original fw sources files provided in order to generate the same binary file before proceeding to fw changes. I have all the files using version 2.1.0.0 The only changes that I made are:1) Add the preprocessor define EVAL=1...
Hi, I work on the NFC01A1 and want to write in the M24SR with i2c protocol in python. My goal is to put a URI in, "abc.com" in this example. Here, I will put only the 3 important parts of the code, Erase Message Length, Write Message, Write Message L...
Hi,I want to use the ST25R3911B with a MEMS clock source. Is there any possibility to do this? Regards, Simon
Hi, I am using X-NUCLEO-NFC03A1 and NXP NTAG213 Mifare Ultralight. I chose this kind of TAG because they can be protected by password. I downloaded all files like user manual, etc... about NFC03A1 but I couldn't find any informtion about password wri...
I designed an amplifier to increase power up to 5 w at the output to achieve larger reading distance,however once it operates at its full power i get no readings and when i reduce the output power to 200-400 mW i get readings however the performance ...
Hello,My design must be very low power consuming. So, I am intended to reach 50 uA while waiting for a card by using the Tag detection mode.Is there any other approach so as to decrease those 50 uA while waiting for a transponder?Reagards, Ramon
Hi ,We have done preliminary test on X-Nucleo-NFC05A1 and than made our custom board using the reference circuit provided.We have followed the sequence for Card Detection:Now the the function work as follows:rfalInitialize() gives ERROR_NONE st25r391...
Hello,I have used the dev kit PLUG-CR95HF-B for the CR95HF, but it seems not to be available anymore.I want to use it for a new development and I need to confirm some points before.What is the roadmap for CR95HF?What is the ercommended devkit for CR9...
