| 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. | |||||
