Hello,I would like to confirm the correct procedure for measuring antenna impedance using a NanoVNA. The chip under test is the ST25R3916.I came across the post titled "How to Measure Antenna Parameters According to AN4974 with NanoVNA," which was ve...
Hi, I am using a customer board with h7. Similarly, I want to read a simple nfc card using the st25r3916 chip. For this, I made the necessary adjustments using RFAL libraries without using the cubeMx ready package.I have completed the necessary hardw...
I am currently working on a project that involves reading NFC tags using the NFC X-NUCLEO-NFC08A1 extension, which utilizes the ST25R3916 NFC reader connected to an STM32 Nucleo-G0B1RE platform.Having completed the hardware interfacing for SPI commun...
Hi, We are developing a prototype containing a st25r3916b nfc reader. When the prototype is idle it goes into sleep mode and wakes up through the wakeup function. When we actively poll for a card from our MCU we can read a UID from a distance of abou...
We are currently seeking layout recommendations for the ST25R3916 and ST25R3918 chips.On the Transmitter Side:ST25R3916B → Power Amplifier → Matching Circuit → AntennaOn the Reciever Side:Antenna → Matching Circuit →Power Harvester → ST25R3918The imp...
Hi,I am currently working with the X-NUCLEO-NFC08A1 as reader another PCB with a stm32 microcontroller and a ST25DV04K tag. I don't have access to the source code of the board with the tag but i know the used protocol to interact with it.I got everyt...
For my setup, I am using a nucleo-L476RG and a NFC08A1. I am wanting to learn bare metal programming to really grasp micro controller programming. I have programmed some smaller bare metal programs, SPI, I2C, etc on the nucleo. Now, I am trying to...
hi, I have some code for reading/writing to a mailbox from the ST25R3916B transceiver to a ST25DV64KC tag. The read passes but the write fails every time;its errcode is ERR_PROTO;My code is following:static void demo2Nfcv(rfalNfcvListenDevice *nfc...
Hi everyone,I'm currently working with the X-NUCLEO-NFC08A1 expansion board and using the ST25R3916 NFC reader IC with an STM32L010RB microcontroller.When I call rfalNfcInitialize(), the initialization process fails and enters the error handler. Aft...
Hi,I am designing an NFC reader based on the ST25R3916B for a payment interface, ensuring compliance with EMVCo standards. For hardware development, I am using the ST25R3916B-EMVCO reference design as my baseline.Queries:Custom NFC Antenna Design:I p...
