Hello, I am using the ST25R3916 reader. looking at the schematic of the filter and matching circuit I notice that the cutoff of the filter is lower than 13.5 M. I would like to double-check the L and C of the filter : 270 nH and 680 pF , thanks
We are evaluating ST25R3911B using the X-NUCLEO-NFC05A1 board, with our custom IMX6 system. We have tried RFAL with the nfc_poller_st25r3911 example. Initially, no tag was found. We determined that the problem was our long IRQ handling. Since we had...
When I set the tx power as 25 dBm in the application what would be output tolerance. What would be the output power accuracy?We understand that tolerance resolution would be the parameter to drive the step size. RegardsPrabhu
Dear Sir/Madame,I'm currently using ST25R95 for a design and I have a question from my software colleagues. Is the device capable of writing on Tags with a protected acess (by password for example) ? We are using NFC TAGs Type 1.We would like to gar...
From reading the ST25R3916 datasheet, it seems like using the MCU_CLK output as my microcontroller clock source will ultimately generate less undesirable noise and save on additional parts. My mcu and rf circuit will all be inside the antenna much l...
Hello!I using X-CUBE NFC-6 library on X-NUCLEO-NFC06A1 board in Card Emulation mode and writing on "tag" (board) 300 bytes of data and it causes hard fault during next read or write "tag". I think it's a bug in library, can you help me with that prob...
Hi. The only example of software that drives the ST25R3911B's capacitive sensor function I've found is the Discovery GUI. But there's evidently no source code available for the GUI. Is there any available code demonstrating the capacitive sensor Wake...
I was working with the two ANT-1-6-ST25DV boards. But I could not find the schematics of these boards. Does any one have it??
I try to read tags with the configurations:Coding = FM0BLF = 640hzTari = 6,25usAnd I didn't get sucess. But when I try to read tags with the same configuration with EVAL Board I did get sucess. I don't know what is diferent, because I use the SDK 2.3...
I need at least 10 IC's for a field test and its impossible to get any right now it seems. I'm trying to remember if there were samples in the ST25R3916-DISCO package? Can someone confirm if sample IC's are included?
