Hi,I have a device that should normally be in Standby mode. Eventually it will need to wake up when a NFC tag is read, and then do some stuff (and retain the info of the tag).At the moment I got the STM32H7 to go to Standby mode, and is waking up tha...
Hi there,I am a beginner of using customize board to build a project for reading a ISO 144443-4 card . The project demo(polling) that I search in previous post is using a different MCU. Also, I read the rfal_platform header file. It is using the SPI ...
I have a project where a sensor of mine reads a frequency value of 7 digits (5000000 for example) and is sent to a ATTiny414. I want to write this data on to the ANT7-T-ST25DV04K through I2C. I can't use the STMDuino library as the microcontroller ho...
Hello,I'm working on a custom application with a board with a previous Firmware (V3.1.0) that works well. I have a 2nd board with the newest Firmware version(V3.2.1.0) that does not work with it. Any way to have access to a previous firmware V3.1.0.0...
How to simply use firmware for custom project? Which functions are necessary to scan tags? Example in gen2.h requires almost all files included in the project, which creates many errors when compiling. P.S. I have successfully read chip version, so w...
The ST25RU3993 is flagged as NRND and Digikey reports the part as EOL.The product is great. Is there a replacement planned?
I´d also like to connect the X-NUCLEO-NFC08A1 to a Raspberry Pi 3 or 4 but want to avoid using an ARPI600. The fact that you either need to fix a hardware pin of the X-NUCLEO-NFC08A1 board or the ARPI600 makes me feel that you are not a big fan of th...
We have designed a a custom PCB with a custom antenna using ST25R95 NFC Tag reader, also the antenna tuning has been done. We found an issue during our testing, at our production site the tags are not getting detected but the same PCBs are working fi...
As the radio equipment standards are very important for entering EU, CN, and USA markets, could you help to communicate with the supplier to provide the information about the standards that must be confirmed as the radio equipment? Such as EN 301489-...
