PN522 reader as keyboard using Cjmcu Beetle (ATMEGA32U4)

PN522 reader that send data as keyaboard to PC using an CJMCU Beetle (ATMEGA32U4)
Beetle programmed as Leonardo using Arduino IDE 1.8.5. PN522 set as I2C using dip on module (1=on 2=off). A yellow led with resistor is on when ready, active buzzer beep when good, double beep when wrong card (and led blink). I read max 16 char from card in block 5. I add < and > char for my purpose. Very hard to send to my italian keyaboard, keyboard.h library is for english keyboard scancode
