Hello, Can I configure ST25 reader to send only 13.56 MHz carrier ? if So how to do that?
You just need to enable the Oscillator (en bit in register op control), wait for I_osc, and then set tx_en => constant wave.
thanks for the reply do you recommend a specifi ST25 reader ?
to date there is only one chip available on the boards in the web shop: ST25R3911B. You can either get it as ST25R311B-DISCO with a PC software or as a nucleo shield: X-NUCLEO_NFC05A1.
ST25R3912 .. ST25R3915 are compatible variants.
For your own developments the nucleo shield might be more suited.
I have now the TR25R3911B-Disco. folowing your previous response couled you please guide me more for this steps:
please have a look into the DS (https://www.st.com/resource/en/datasheet/st25r3911b.pdf ): Search for 'en' 'I_osc', etc.
Transparent mode has 0xdc, no 16 bits!
