# 运行 运行工具: 运行你的命令行工具时,输入数据需要以十六进制格式提供,并且可以指定控制字符: ```bash python main.py -m encode -i "16A" -c 1 python main.py -m decode -i "16A" ``` # encdec8b10b Encode and decode 8B10B encoding ## Get ``` python3 -m pip install encdec8b10b ``` ## Usage ### Encode Data Byte ``` from encdec8b10b import EncDec8B10B running_disp = 0 byte_to_enc = 0xf running_disp, encoded = EncDec8B10B.enc_8b10b(byte_to_enc, running_disp) print(hex(encoded)) Output >> 0xba ``` ### Encode Control Byte ``` from encdec8b10b import EncDec8B10B running_disp = 0 byte_to_enc = 0xbc # comma ctrl = 1 running_disp, encoded = EncDec8B10B.enc_8b10b(byte_to_enc, running_disp, ctrl) print(hex(encoded)) Output >> 0x17c ``` ### Decode Data Byte ``` from encdec8b10b import EncDec8B10B byte_to_dec = 0xba ctrl, decoded = EncDec8B10B.dec_8b10b(byte_to_dec) print(hex(decoded)) Output >> 0xf # ctrl variable confirm that it was a data byte print(ctrl) Output >> 0 ``` ### Decode Control Byte ``` from encdec8b10b import EncDec8B10B byte_to_dec = 0x17c # comma encoded ctrl, decoded = EncDec8B10B.dec_8b10b(byte_to_dec) print(hex(decoded)) Output >> 0xbc # ctrl variable confirm that it was a control byte print(ctrl) Output >> 1 ``` ### Verbosity Both functions have a verbose-mode to make it easier to confirm everything that's happening: ``` from encdec8b10b import EncDec8B10B running_disp = 0 byte_to_enc = 0xA0 running_disp, encoded = EncDec8B10B.enc_8b10b(byte_to_enc, running_disp, verbose=True) Output >> Encoder - In: A0 - Encoded: 146 - Running Disparity: 0 ctrl, decoded = EncDec8B10B.dec_8b10b(encoded, verbose=True) Output >> Decoded: A0 - Control: 0 ``` ## 8B10B 8B10B Encoding were implemented by Al Widmer and Peter Franaszek in 1983. It is still widely used in high-speed electronics. - [Original article](https://ieeexplore.ieee.org/document/5390392) - [Wikipedia](https://en.wikipedia.org/wiki/8b/10b_encoding)
