Not able to use RFID / RC522 on ESP8266 / NodeMCU 0.9
Posted: Sat Oct 03, 2015 6:03 pm
So I got a RC522 wired up to the NodeMCU 0.9 like this:
SDA > D4 (GPIO02), SCK > D5 (GPIO14), MOSI > D7 (GPIO13), MISO > D6 (GPIO12), GND > GND, RST > D8 (GPIO15), 3.3V > 3.3V
https://github.com/Jorgen-VikingGod/ESP8266-MFRC522 using the sketch here but I dont get anything in serial.
Neither can I flash it when the RC522 is connected to the breadboard.
Also I have tried to solder up a second RC522 and connect it with the same issues.
Does anyone have a idea?
