    (1) there are some old (deprecated) Python Cyton stream decoders in the '-archive' repos. OpenBCI_Python and pyOpenBCI.

    (2) the byte stream can contain all 256 (0x00 to 0xFF) byte values. There are no 'unknown' bytes, as this range contains everything possible.

    The SECOND image you posted has nothing unusual in the areas that you highlighted in blue. Eight bit bytes contain the ASCII character table with printable characters. This corresponds to bytes missing the top, high-order bit.
