sheralikhan 4:9d923c6e6c14 2
sheralikhan 3:f9ed412458d5 3 1.This program is for reading and writing from /to MIFARE Classic 1k ,MIFARE Ultralight MF0ICU1,MIFARE Ultralight NTAG213,MIFARE Ultralight NTAG203
sheralikhan 3:f9ed412458d5 4 2.Generally we are using MBED model WIZnet WIZWiki W7500 to interfacng with MFRC522 Rader and writer device using SPI protocol
sheralikhan 4:9d923c6e6c14 5 3.This program is designed such a way that it will take input 1,2 for reading or writing from serial monitor
sheralikhan 3:f9ed412458d5 6 4.Once user can entering input based on input it will call read and write function respectively...
