Hi all , we have designed a custom board based on the ST25DV SMARTAG1 reference design with a 18.5cm *22.5 cm antenna as ST25DV-DISCOVERY-ANT-C1 . Our product is batteryless so we need to power it entirely by energy harvesting output.Before making ...
Any one who has successfully drive the eval board with Arduino via spi?I am trying to drive the ST25RU3993 Eval board using SPI, with my Arduino Due (i read an earlier post on that ran at different voltage and solve using 3V arduino board, in my cas...
Hello,i have been trying to put the st25r3916 in wake-up mode but i detect high power consumptions (around 900 uA). I am using a very basic code just to test current consumtion, i2c communication seems to work, but maybe i am missing some parts.int m...
Hello,I am using ST25R3911 to read ISO15693 tags with the ST example from X-CUBE-NFC5. Everything works fine, now, I would like to read memory of Mifare Ultralight (without encryption). I know that st25 can't read Classic Mifare, but I don't find the...
I am wondering why it was necessary to use 6 layers PCB board for ST25RU3993 Evaluation board ? As outlined in the documentation, layers are as follow: Top Layer - RF GND Layer - Power Layer- GND Layer Routing Layer -Bottom GND Layer.I want to chang...
Where do I find top IC marking?? Should not it be in the datasheet? Customer wants to check parts coming onto their CEMRgds Yves
The X-Nucleo-NFC06A1 mentions 1.7W output power with differential antenna.I understand that the ST25R3916 chip is capable of 1.7W max output. I've been unsuccessful in finding out what the output power of the DISCO board is.
I’m using NFC05A1 and the STMF4xx-Nucle-Polling project. I’d like to interact with a Mifare classic card 1K. I am aware Stm won’t provide any code that would deal with encryption and this is not what I’m asking for. The issue I encounter is about t...
