Resolved! SPI interface for STM32L476VG

STM32L476VG is the MCU we are interfacing with ST25R3911B using SPI.what we have understood from some search is that we need RFAL (abstraction layer) to interface with RF HAL.Then once we integrate RFAL and RF HAL in our system workbench(ac6) project...

Resolved! ST25R3911B Collision Resolution returns TIMEOUT_ERR

Hi,I have ported RFAL library to ESP32 platform and have set up proper interrupts for it to function in capacitive wakeup mode.So the issue:We are using RFAL-HL ( higher layer ) in our project ( based on X-Cube-NFC5, but using the latest version of R...

Resolved! What's the unit of the variable "deviation" in the evalAPIcommands.c file?

In the evalAPIcommands.c file have the function "reflectedPowerTooHigh()" in the line 907. The goal of that function is to calculate the value of the reflected power and the deviation variable received this value, but don't have a comment in code say...

Resolved! How to get read per second and time stamp of read from ST25RU3993 SDK?

I would like to get the time stamp of read and read per second of one tag. Which is the best way to implement the same using SDK? I would like to get the timestamp of each read as in ST25RU3993 Reader Suite.

Resolved! RSSI Measurement via ST NFC Sensor App

Hello,I am a newbie to the field of RF communication. I am planning to design an antenna using the ST25TV IC. Ultimately, I want to measure the Received Signal Strength Indicator (RSSI) value of the RF communication. I am thinking of using the ST NFC...

Resolved! ST25R3911 Detects NFCV Tag Got ERR_RF_COLLISION Return Code

Hey, I'm using ST25R3911 and ST RFAL Lib, and a 15693 tag on my customized board.I was using an iPhone to detect the tag and it works. And I was using NFCA tag, the ST25R3911 and the Lib work good.But as I move on to the NRFV tag, the board can detec...

Resolved! X-NUCLEO-NFC06A1 over i2c

Hello, I want to use X-NUCLEO-NFC06A1 with an esp32 pico kit over i2c. I have the read/write functions from esp and I can read a register from the module. I want to use the code you provide to read an nxp ntag (ndef_t2t.c in x-cube examples has some...

Resolved! I have designed a board that uses the CR95HF-VMD5T and am using SPI to communicate with it. I cannot find production qtys of this. Is the ST25R95-VMD5T a drop in replacement since I am not using the UART feature of the CR95?

I know that it is the same package and pinout, but will my firmware just work when I move to this part? Thanks a lot, John
