I am experiencing spurious lockups of the I²C interface of an M24SR02-Y (see a separate post). Due to time/development constraints, it may be the easiest to simply cycle power to the device when this problem is detected. The datasheet is, however, no...
I'm working with a custom tag that needs to be powered by the radio wave field between a select command and a read one.Is there any way to accomplish this using the API or it must be done on register level?
We have ordered ST25-TAG-BAG-U. I want to write a password protected data on ST25TV02K tag from it.I have downloaded ST25 anroid application to communication with tag.Using Application I can read & write NDEF text on tag using ISO/IEC 15693 protocol ...
I need documents(datasheet, user manual etc..) related to ST25RU3992 as it is not available on the st website.
I have heard the ST25DV can be used to upgrade the Firmware of any STM32 Microcontroller. I would like to understand how this is done. Also how the PINs needs to be connected to the STM32. Or is the code transfered via I2C? If so, how does the STM32 ...
Hi,I’m trying to use the CR95HF in what I think should be the simplest mode. Reading a 14443a tag.I am controlling it from a pic micro. I have detailed exactly what I have done. Clearly the SPI is working but I am also missing something. Really appre...
Hello guysI'm using the STM32F070CB MCU in a custom board connecting SPI pins and IRQ pins to the MCU and trying to scan for NFC devices. We've tested the board and the ST25R95 with std32duino libraries and we could make it work, but we needed to see...
I have been working on a project with CR95HF multi-protocol transceiver IC. The obvious advantage of it is that it can read tags working with different protocols (different standards). I already coded so the IC reads different standards according to ...
Hi thereIt seems that ST25DV64K-IER6S3 does not load the I2C bus even when there is no power on VCC. I have checked the datasheet but I have not found any information on that.Could you confirm it?BRGilberto
