I am trying to run this code: https://github.com/miguelbalboa/rfid/blob/master/examples/ReadNUID/ReadNUID.ino
Using an ESP8266 based D1 board and an RFID-RC522.
I am not able to get it to detect the rfid tags ...
the serial monitor just shows:
ets Jan 8 2013,rst cause:4, boot mode:(3,4) wdt reset load 0x4010f000, len 1384, room 16 tail 8 chksum 0x2d csum 0x2d v00000000 ~ld
The "Typical pin layout used" section of the above document does not mention any connections on the 3.3V & GND pins of the RFID-RC522 card.
Does this mean that I do not need to connect them?
Or is is just so obvious that I should connect them that they did not bother to write it in that section?
