Bogus frames detection in the decoder #65

Closed githubDante closed 1 month ago

githubDante commented 1 month ago

The decoder will show extra line when such frames are detected. Example:

========== RTU Payload - [Response] ==========
        Slave address: 1
        Function code: 3
        CRC: 00 (valid: True)
        BOGUS FRAME DETECTED - REAL CRC: eb4e
        Quantity: 115

NB: Created a bit of a mess as I forgot to sync before the push.

Yup it's working:
