Convert a stream of packed bytes or shorts to stream of unpacked bytes or shorts.
input: stream of unsigned char; output: stream of unsigned char
This is the inverse of gr::blocks::unpacked_to_packed_XX.
The bits in the bytes or shorts input stream are grouped into chunks of bits and each resulting chunk is written right- justified to the output stream of bytes or shorts. All b or 16 bits of the each input bytes or short are processed. The right thing is done if bits_per_chunk is not a power of two.
The combination of gr::blocks::packed_to_unpacked_XX_ followed by gr_chunks_to_symbols_Xf or gr_chunks_to_symbols_Xc handles the general case of mapping from a stream of bytes or shorts into arbitrary float or complex symbols.

declare_sample_delay(packed_to_unpacked_ss_sptr self, unsigned int delay)
pc_input_buffers_full_avg(packed_to_unpacked_ss_sptr self) -> pmt_vector_float
pc_output_buffers_full_avg(packed_to_unpacked_ss_sptr self) -> pmt_vector_float
Convert a stream of unpacked bytes or shorts into a stream of packed bytes or shorts.
input: stream of unsigned char; output: stream of unsigned char
This is the inverse of gr::blocks::packed_to_unpacked_XX.
The low bits are extracted from each input byte or short. These bits are then packed densely into the output bytes or shorts, such that all 8 or 16 bits of the output bytes or shorts are filled with valid input bits. The right thing is done if bits_per_chunk is not a power of two.

declare_sample_delay(unpacked_to_packed_ss_sptr self, unsigned int delay)
pc_input_buffers_full_avg(unpacked_to_packed_ss_sptr self) -> pmt_vector_float
pc_output_buffers_full_avg(unpacked_to_packed_ss_sptr self) -> pmt_vector_float
Converts a stream of bytes with 1 bit in the LSB to a byte with k relevent bits.
Constructor Specific Documentation:
Make a pack_k_bits block.
| Parameters: | k – number of bits to be packed. |
|---|
declare_sample_delay(pack_k_bits_bb_sptr self, unsigned int delay)
pc_input_buffers_full_avg(pack_k_bits_bb_sptr self) -> pmt_vector_float
pc_output_buffers_full_avg(pack_k_bits_bb_sptr self) -> pmt_vector_float
Pack bits from the input stream onto bits of the output stream.
No bits are lost here; any value for k and l (within [1, 8]) is allowed. On every fresh input byte, it starts reading on the LSB, and starts copying to the LSB as well.
If a packet length tag is given, this block assumes a tagged stream. In this case, the tag with the packet length is updated accordingly. Also, the number of input bits is padded with zeros if the number of input bits is not an integer multiple of , or bits are truncated from the input if is set to true.
