I connect the module to a raspberry pi 3 through SPI, compiled and executed sudo./demo/nfc_demo_st25r3916. I changed the interrupt pin to physical pin 11 because the default was busy.The demo stays at scanning and never detects the module.I ran it ...
my setup is st25dv04k connected with tag on instrument A. cr95hf connected with instrument B. when instrument A comes near to instrument B. i want to confirm that instrument be successfully message in a tag [ which connected to instrument A].on succe...
I made a new board based on the EVAL board (removing single ended xmit).My issue is even after tuning the radio, my tag detection performance is below the eval board (same parts/layout as far as I can tell, minus 2:1 mux for switching tx paths).Is th...
Hello All,I'm trying to receive tag ID through st25r3916 discovery board. I read out the register through PC GUI software tool and try to mimic it on my firmware. I'm new to this board even RFID. I did not find any library that can help to develop my...
I see the ADC Pin runs to the STM32 MCU ADC Pin, and that in the firmware demos it prints the adc value to the screen.However I don't see any place the ADC value is used for tuning or anything else other than just random information.For example, for ...
I use the standard function " STUHFL_T_RET_CODE Gen2_Lock(STUHFL_T_Gen2_Lock *lockData) " to Lock a Tag, But now I wanted to unlock the same Tag and following the standards information in Gen2 protocol Like the pictures below, I try using the same fu...
Hello I designed a single sided Antenna now i recieved the PCB's soldered the ST25DV04K onto it, but my phone can't find the Tag. Is there a possibility without a network analyser to trobleshoot such a PCB/design?Or would is it better for troublesh...
What is the hardware,output power difference between ST25RU3993-EVAL &ST25RU3993-HPEV
Hello, I am using the polling demo example from the RFAL library (STM32CubeExpansion_NFC6_V1.1.0) and added it to my custom application. My work now just requires me to use NFC-V tags. Therefore, I only selected RFAL_FEATURE_NFCV but it appears the c...
Hi there,I am new with St25dv04k NFCI want to send data from RF to I2C using ST25DV04K IC by following AN4910 I have followed all the procedure as written in the Application note. I am getting the interrupt but unable to transfer the data from the ...
