//Test of cheap 13.56Mhz RFID-RC522 module
//Connect as follows:
//RFID pins -> WIZWiki-W7500 header CN5 (Arduino-compatible header)
//----------------------------------------
//1.RFID IRQ -> Not used. Leave open
//2.RFID MISO -> WIZWiki-W7500 SPI_MISO =D12
//3.RFID MOSI -> WIZWiki-W7500 SPI_MOSI =D11
//4.RFID SCK -> WIZWiki-W7500 SPI_SCK =D13
//5.RFID SDA -> WIZWiki-W7500 SPI_CS =D10
//6.RFID RST -> WIZWiki-W7500 =D9
//3.3V and Gnd to the respective pins
