Encode and decode may be a bit missleading at first sight... The textual representation is a hex dump: e.g. "40 41" The "encoded" data of this is the binary form, e.g. b"@A" Therefore decoding is binary to text and thus converting binary data to hex dump. )absolute_importNZ0123456789ABCDEFstrictcCs tdd|Dt|fS)'40 41 42' -> b'@ab'cSsg|]}t|dqSint.0hr W/var/www/html/myproject/myenv/lib/python3.8/site-packages/serial/tools/hexlify_codec.py (szhex_encode..)serialto_bytessplitlendataerrorsr r r hex_encode&srcCs&tdddt|Dt|fS)b'@ab' -> '40 41 42'css|]}dt|VqdSz{:02X} Nformatordr br r r -szhex_decode..)unicodejoinr iterbytesrrr r r hex_decode+sr#c@s eZdZdddZdddZdS) CodecrcCstdd|DS)rcSsg|]}t|dqSrrr r r r r3sz Codec.encode..)rrrselfrrr r r encode1sz Codec.encodecCstdddt|DS)rrcss|]}dt|VqdSrrrr r r r7szCodec.decode..r r!rr"r%r r r decode5sz Codec.decodeN)r)r)__name__ __module__ __qualname__r'r)r r r r r$0s r$c@s<eZdZdZdddZddZddZd d Zdd d ZdS)IncrementalEncoderzIncremental hex encoderrcCs||_d|_dSNr)rstate)r&rr r r __init__=szIncrementalEncoder.__init__cCs d|_dSr.r/r&r r r resetAszIncrementalEncoder.resetcCs|jSNr1r2r r r getstateDszIncrementalEncoder.getstatecCs ||_dSr4r1)r&r/r r r setstateGszIncrementalEncoder.setstateFcCs|j}g}|D]|}|tkrRt|}|rD|||d@d}qd|d>}q|dkrv|rp|jdkrptdd}q|jdkrtd|q||_t |S) z Incremental encode, keep track of digits and emit a byte when a pair of hex digits is found.
