Bitfields

[thesamprice]

Not sure how I would do this with the DataStream object. In python / C I would do something like

class CCSDS_PriHdr_t_StreamId (my_endian):
    """Some comments"""
    _pack_ = 1
    _fields_ = [ ("packet_version_number"    , ctypes.c_ushort ,3),
                 ("packet_type"              , ctypes.c_ushort ,1),
                 ("secondary_header_present" , ctypes.c_ushort ,1),
                 ("apid"                     , ctypes.c_ushort ,11)]

This would create a 16 bit ctype structure with 4 fields of bits 3,1,1,11. Trying to stream data from an embedded device and then decode it in a browser.

Yeah, this would be cool to have. Some way to pack & read data by bit. I've got a single-bit access helper at https://github.com/kig/bitview.js, but it doesn't do "treat these 3 bits as the LSBs of an uint".
