I would like to know if someone can share an example along with the library to read/write NFC. I have connected the nrf52840 board to the MOB240627022 antenna from seeed-studio.
I can’t locate the library that uses the seeed-s example NFCT.h or something that I can download.
thanks!!
Hi there,
and Welcome here.
So there are a ton of examples of doing the NFC with Arduino?
here is a link to one:
If your using a Xiao , and HAVE read the Wiki on it, You understand its a TAG in the real sense of NFC (ONLY) you can edit a flash location or string that the NFC burps out when NFC is red.
NOTE: you must use the correct BSP for the older demos to work so be mindful of that.
read the threads on here on the subject to get up to speed.

FYI,
the antenna connections for the NFC is on the bottom and needs the proper resistors to match it and work. this antenna isn’t for the XIAO specifically but maybe could be adapted?
