Modules

Run the modules via minicom or other serial interface. serial interface on Pico will interact with MicroPython To learn how to communicate with MicroPython of Pico in Windows using WSL, read THIS ARTICLE.

readRFID

This module is used to read data from RFID card, to use

import readRFID
readRFID.RUN()

writeRFID

This module will write 16bytes of data at address 0x08, this can be changed at -

stat = rdr.write(8, b"\x44\xFF\x4d\x6f\xFF\x47\xFF\x49\x6d\x6d\x55\xFF\x73\x4a\x44\x65")

Then run the module -

import writeRFID
writeRFID.RUN()

KeyGen
