ESP8266 12E NodeMCU V3 connect with PN532 nfc
Posted: Mon Oct 26, 2020 2:49 pmHello everyone!
I am trying connect my ESP8266 ESP-12E CH340G NodeMCU V3 with PN532 NFC chip.
But NodeMCU can't find my NFC Chip.
nfc.getFirmwareVersion() is always 0
Here is my code (Using newest libraries from github):
Here is my connection:
I have also tried connect SS to D4 but same result.
Thanks everyone for your help !
