The script processes a raw HEX string input (representing an FDX-B transponder) and extracts relevant fields, such as the header, identification code, country code, data block status, animal application indicator, CRC checksum, and extended data block.
- Dynamic Imports: It dynamically imports required libraries (
binascii
,argparse
,termcolor
), displaying errors if any library is missing. - HEX Processing: It converts the input HEX string into binary and extracts the fields following the FDX-B protocol structure.
- Manufacturer Lookup: Based on the country code, it enriches the output by displaying the manufacturer's name (if available).
- Colorful Output: Uses the
termcolor
library to colorize the output fields for better readability. - Error Handling:
- If no HEX string is passed, it displays a usage guide and prompts the user to provide valid input.
- If an invalid HEX string is passed, it catches the error and prints a helpful message.
