Hello,I'm currently using STSW-ST25R011 firmware.At first, I was going to read/write with NFC type 2, but the firmware above is only read implemented, so I added Write.(The Write implementation was implemented using t2t.c in folder firmware/Middle...
I've created my own differential AAT board (3 turn 80x36mm antenna) that is working, but with a range of only 4cm compared to the NFC06A1 range of 8cm using a similar 15693 tag . With my own board powered off, I used my miniVNA to measure the matchi...
Hi everyone,I can communicate with ic via i2c. I can write/read on user memory section but when i try to write static registers, i faced foolish value. For example, firstly i read MB_MODE register and value is default '0' then i write '1' on this reg...
How can i use FTM buffer i do not understand what should I do exactly. I have problems first step. I can read all block of system memory , user memory and dynamic registers also i can write on user memory(EEPROM) but when i try to initalize Fast tran...
From where i can find the size of memory address size ?i want to find generic approach to find size of memory address to write and read .So in which section it get mentioned inside datasheet or user manual?
Hello,i want to design a new antenna layout with the ST253911b chip.It is recommended to match the antenna across RFO1 and RFO2 to a load impedance of 10 Ohm.Do i have to change the register "RFO normal level definition register" adress 27h to 10Ohm?...
Using a Raspberry Pi, I have been able to successfully connect to and read tags from NUCLEO-NFC05A1, NUCLEO-NFC06A1, and ST25R3916-DISCO. However, I am unable to get ST25R3911B-DISCO to work using the ST25R3911B Linux drivers. For some reason the Ras...
Hello allI use ST25DV64K.If the I2C communication is normal, it returns ACK after receiving data, and after receiving the last data, it returns NACK response and issues Stop Condition.If the I2C communication is abnormal, and the master issues a stop...
