n2k-gen

Code generator for NMEA2000 messages from pgns.xml of canboat (https://github.com/canboat/canboat/blob/master/analyzer/pgns.xml) and NMEA2000 CAN bus parsing library based on embedded_hal_can.

n2k-codegen

Code generator for PGN parsers from completed N2K messages.

n2k

Built to transparently handle multi-part n2k messages on top of a CAN bus abstracted by embedded_hal_can. Interfaces with the generated code by the code generator through the PgnRegistry trait.

n2k-test

Parse candump and print decoded messages on the command line.

TODO

• Interface to identify fast packets and assemble
• Sending
  • Single frames
  • Fast packets
  • ISO Transport Protocol multi-part messages
• Receiving and re-assembling of ISO Transport Protocol multi-part messages
• ISO functions
  • Address claim
  • Product Information
  • Device Information
  • Transmit Messages
• Example test project
• Sub-PGN message decoding/proprietary PGNS. Example: PGN 130820 represents multiple possible Fusion messages, the key in the XML disambiguates between different types

Failing PGNs

These PGNs currently don't generate properly for reasons:

• 129540 / gnssSatsInView: variable length
• 130820 / Fusion: proprietary PGN
• 130311 / environmentalParameters: duplicate id name
• 129029 / gnssPositionData: slices
• 65288 / seatalkAlarm: duplicate enum names
