Hi STNow I am using ST25R3916B evaluation board, it works well with the project code you provided.My final target is using 3920B on automotive for demostrating NFC card detection as well as digital car access to customer.But we will finally change to...
I am using a custom PCB based on ST25R3911B + STM32F072C8T6, and I am encountering an issue where FeliCa cards cannot be read.Initially, I used the X-CUBE-NFC5 software package downloaded from ST’s official website, along with the integrated RFAL lib...
I am entering the world of NFC with a somewhat complex project, but I took the initiative to start it. The goal was to create a sensor that would work only with Energy Harvesting from the reader.For this, I chose the ST25R300 chip to be the chip for ...
Hello everyone,I am using the X-NUCLEO-NFC10A1 NFC reader with an NXP MCU.I am able to successfully detect a MIFARE Classic 4K card using this reader.However, when I try to authenticate a sector for read/write access, I encounter an issue.I am sendin...
Hi,I am using the st25r3916b chip with phase awaken, wake-up timer range of 800 msec and delta 3.Once it wakes up, I go to read the value in the register 0x3A (Phase measurement display register) in order to check which is the difference between of t...
It is getting hang at this point, going to infinite loop MCU: STM32F407SPI1 InterfaceTried ST25R_SELFTEST as well same problem
Hi, we use the ST25DV16KC and for development i use the ST25R3911B. Problem is: ST25R3911B connected via micro usb to the pc. so far looks good Pressing the TAG Editor Button I just want to read the config: Pressing Button Read Configuratio...
HiFrom the ST25R3919B datasheet, I cannot find or understand the voltage level of EXT_LM. Does the EXT_LM voltage level depend on the VDD supply?”BR
Hi I am evaluating NFC function on your STEVAL 25R3916B board, but I would like to see how it works with the I2C interface. Currently, the default configuration is SPI.I have downloaded STM32CubeIDE and STEVAL-25R3916B_V2.1.0 project code, but am not...
Dear STMicroelectronics TeamI am currently developing a wearable board (WB) that integrates NFC communication and wireless charging features. For this design, I am considering using the ST25DV64KC as the NFC Dynamic Tag and the ST25R3916B as the NFC...
