Hi,i have modified 2 eval NFC08A1 and now i'm using ST25R3916B not in balance mode but with 2 single ended RF circuitry.If i use the RFIO1 i can establish a P2P connection between the 2 evals, insted if i change and use the RFOI2, the P2P connection...
Hi,Reader IC - ST25R3916RFAL version - 2.8.0Serial interface - I2CI am trying to read the entire memory (2KB) from ST25tv16k using the api rfalNfcvPollerExtendedReadMultipleBlocks.eg:- err = rfalNfcvPollerExtendedReadMultipleBlocks(flags, NULL, bloc...
ST25R3917 doesn't commnicate on the I2C (Address 0x50) it seems like the chip doesn't start. Maybe a problem with the crystal?- Drawn current is 50uA- Signal on MCU_CLK is a 32.5kHz Squarewave- IRQ line stays lowI assume that the capacitance on the 2...
Hi,Do you have an errata document for the RFAL library ? How can the customers know if there is an updated RFAL library ?Best regards,
We're evaluating the ST25DV04KC for our application. We want to write to the ST25DV04KC from NFC and read the info from I2C from our MCU.We're able to use NFC app on the smart phone to write an NDEF Text of "12345". We can read it via NFC. But readin...
Hi @Rene Lenerve @JL. Lebon @Brian TIDAL So basically I am connecting ST25DV64KC tag with MKE14F512VLL16 based controller and I want to write on the tag through i2c but as I am sending data using I2c write and as I am checking using Logic analyzer ...
Hi Community,I´m trying to import this driver for my custom board,fp-sns-stbox1/Drivers/BSP/Components/st25dvxxkc/st25dvxxkc.c at main · STMicroelectronics/fp-sns-stbox1 (github.com)could someone explain this more? why should NULL be written in ICREF...
Hi, we are using ST21NFCD in one of our wearable products. I am referring to the document: "AN_21NFCD_Antenna_Matching_RF_Config Rev 7" to know about the NFC antenna design and tuning. It is mentioned here about the application tool used for impedanc...
Hi community,since I cannot find a suitable LL-driver for reading register with 16bits address, here is my experiment.the nfc tag init function: the ReadID funciton is called, in background is GetICREF function.in low level the BSP_I2C2_Read16 functi...
Hi, I am having some problems with my inplementation.Here is my scenary: + I am using a STEVAL-SAMARTAG1 with one shot mode example code, as my T5T tag. + I am using a NUCLEO-F722ZE board with x-nucleo-nfc03a1 as my NFC reader. My first problem is th...
