Hi, I interface Controller with ST25DV04K and able read and write registers , when i am working on I2C protection on Area1 to 4, In both I2C security session close and open mode i was able to read and right even though i set the Area 1 to Area 4 perm...
the time clock (RTC) on this device (STEVAL-SMARTAG1) seem to be off after half day of running, is there a fix available ?
When i looked into the doc , i found that "To be usable on any MCU, this driver calls several IOBus functions. The IOBus functions are implemented outside this driver, and are in charge of accessing the MCU peripherals used for the communication wi...
Compiling RFAL 1.3.0 on Linux x64 it doesn't work due to 32 bit casting of 64 bit address. can you help me?
Posted on September 21, 2017 at 16:11As we know,RFID has a big market.But we only use R2000 by Impinj to develop new reader.The R2000 is not open source system.So we need a new chip to instead of it. So when do we use the demo of ST25RU3993 or other...
Posted on April 29, 2018 at 16:25Hi,As though there are libraries available for Mac OS X, my simple application randomly (almost always) crashes, and it has something to do with the dynamic libraries provided, specifically streader.dylib.Any thought...
Тhe document «UM2268 User manual ST25RU3993-EVAL board software» describes the graphical user interface software (STSW-ST25RU001) for the ST25RU3993-EVAL board. In the Reader Settings window of STSW-ST25RU001 be present Frequencies panel with possi...
Datasheet says these readers support ISO/IEC 15693 standard for vicinity cards. I need a system with high reliability (99%) read for distances up to 1 meter (0.5-0.7 m as the most probable range). Can I use this IC for building such reader alone, or...
Hi,I am using the X-NUCLEO-NFC04A1 and I am trying to write multiple types NDEFs but only the latest one is read by my phone. Is there any way that I can write some NDEF records? Thank you very much, Best regards, Duy
I am trying to calculate the matching network for my project. In the Antenna Matching document it is mentioned that the incoming signals at RFI pins must be limited to 2.5Vpp. So my question is how to design this voltage divider network? Tool gives ...
