(Micro)Python class to access the MFRC522 RFID reader
Basic class to access RFID readers of the type MFRC522. This is basically a re-write of this Python port for the MFRC522. I tried to strip things down and make them more "pythonic" so the result is small enough to run on Micropython boards. I tried the class so far on the ESP8266 and the WiPy.
Put the modules
examples/write.py to the root of the flash FS on your board.
For the ESP8266 there are multiple solutions to do that. E.g. use the
WebREPL file transfer, or mpfshell.
I used the following pins for my setup:
|Signal||GPIO ESP8266||GPIO WiPy||Note|
|cs||14||"GP14"||Labeled SDA on most RFID-RC522 boards|
Now enter the REPL you could run one of the two exmaples:
For detecting, authenticating and reading from a card:
import read read.do_read()
This will wait for a MifareClassic 1k card. As soon the card is detected, it is authenticated, and 16 bytes are read from address 0x08.
For detecting, authenticating and writing to a card:
import write write.do_write()
This will wait for a MifareClassic 1k card. As soon the card is detected, it is authenticated, and 16 bytes written to address 0x08.
