#82657
Hello,
I am using Arduino IDE and ESP8266. I have connected RC522 and ESP8266 like this:
* pin layout used:
* ----------------------------------
* MFRC522 Node
* Reader/PCD MCU
* Signal Pin Pin
* ----------------------------------
* RST/Reset RST GPIO0
* SPI SS SDA(SS) GPIO4
* SPI MOSI MOSI GPIO13
* SPI MISO MISO GPIO12
* SPI SCK SCK GPIO14
* 3.3V 3.3V 3V
* GND GND GND
I have performed a self test and it gives me an OK. When I put card close to RC522, it gives me nothing. Did anyone had this problem? I had many ideas, like the card doesn't match the standard for RC522, the reader is broken etc. So far I had no success with this.
