X-NUCLEO-NFC08A1 arduino example code. How do I get it to work in single ended mode?

[william44]

Hello,

I have made a custom RFID reader board design which is similar to the X-NUCLEO-NFC08A1. However, it powers antennas in single ended mode with a cable through a u.fl connection. I am running the example code for the X-NUCLEO-NFC08A1 on this custom reader and it is not working. How would I get it to work? The code seems to be running fine on the arduino IDE however the TX pin is not lighting up at all, suggesting that a reader field is not being generated. I suspect the reason for this is that the (#define ST25R3916_REG_IO_CONF1_single   (1U<<7))  register in the st25r3916_com.h file needs to be changed from differential to single ended however I don't know how to do this. Help would be appreciated.

Thanks,

William

Hi,

I think this is now fully handled inside https://community.st.com/t5/st25-nfc-rfid-tags-and-readers/how-to-enable-single-ended-mode-and-disable-aat-for-x-cube-nfc6/td-p/664712. 

I propose to close this one.
