Hi PaulS, thanks for your interest.
1 - The reader is connected to a arduino mega 2560 on port serial1 (pins 18 y 19).
2 - Through the serial port of the Arduino, RFID module prints the response in the computer.
3 - The RFID module returns a problem with the values ??of "CRC-16LSB" and "CRC-16MSB"
4 - I would like to know how I can calculate or know the "CRC-16LSB" values ??and "CRC-16MSB"?
Thank you for your help.
