Installation

Install using pip:

$ pip install minsp

Install package from the git repository:

$ pip install git+https://github.com/nunorc/minsp@master

Note: minsp depends on the bitstruct package that may require a C compiler to install.

Quick Start

Import the SpacePacket class from the package:

>>> from minsp import SpacePacket

For example, to create a new space packet for APID 11 and an arbitrary payload:

>>> space_packet = SpacePacket(apid=11, payload=b'hello')
>>> space_packet
SpacePacket(version=0b0, type=PacketType.TM, sec_hdr_flag=0b0, apid=11,
sequence_flags=0b11, sequence_count=0, data_length=4)

To get the bytes representation of the packet:

>>> byte_stream = space_packet.byte_stream()
>>> byte_stream
b'\x00\x0b\xc0\x00\x00\x04hello'

Packets can also be created from a byte stream:

>>> new_packet = SpacePacket.from_byte_stream(byte_stream)
>>> new_packet
SpacePacket(version=0b0, type=PacketType.TM, sec_hdr_flag=0b0, apid=11,
sequence_flags=0b11, sequence_count=0, data_length=4)
>>> new_packet.payload
b'hello'
