v0.33

First standalone release of libsbp, the native binary messaging protocol used by Swift Navigation devices. This is a core messaging dependency for interfacing and integration with the Piksi GPS receiver.

Specifications

• Centralized and detailed definitions of many, if not all, SBP
  messages output by the Piksi, including messages used only for
  internal development. Previously, some messages were either
  undocumented and created inline by their callers in the firmware or
  the Piksi console.
• Definitions are grouped into files by functionality in a
  machine-readable format, YAML,
  and include some annotated examples and example test cases for
  writers of new language bindings.
• A Python-based generator for our C and Python libraries, as well as
  the Piksi datasheet. This is still a major work-in-progress.

C Library

• C header files for SBP message types and library support for parsing
  such messages. This library is now a dependency of the Piksi
  firmware project.
• Updated Doxygen developer documentation. Available
  here.

Python Library

• Binary parsing for all message types, as well as serial port
  handlers and helpers. This is used by the Piksi
  console. Note that
  because messages are now grouped by functionality, some messages
  that were once imported by import sbp_piksi are now located in
  different Python submodules. If such changes aren't clear, please
  don't hesitate to ask a question on the
  forum.
• The serial port client binary for the Piksi is a part of Piksi's
  tools.
• The latest stable version is available on
  PyPi.
• Updated Sphinx developer documentation. Available
  here.

Datasheet Documentation

• A standalone .pdf
  datasheet
  describing SBP and message layouts.
