Yes, I would like to know too ;-) Makes life a bit simpler.
From looking over the code to try to use this myself as well:
The two GPIOs needed for the RC522 are defined here.
The initializer they're passed into is here.
So it looks like chipSelectPin
is D8
and resetPowerDownPin
is D3
.
Could anyone using the project share a wiring diagram or picture to show all the connections between the (MF)RC522 and the ESP board?
Hey from looking at the PCB design:
3.3V -> 3.3V GND -> GND MISO -> D6 MOSI -> D7 SCK -> D5 SDA -> D8
Since the same pins also exist on the nodemcu I just left the code the same though
Hi! Where do you define the GPIOs? So I can adapt to a NodeMCU. Thanks
