Module waterlevel

source code

Autogenerated python functions to serialize/deserialize binary messages.

Generated by: ../aisxmlbinmsg2py.py

Need to then wrap these functions with the outer AIS packet and then convert the whole binary blob to a NMEA string. Those functions are not currently provided in this file.

serialize: python to ais binary deserialize: ais binary to python

The generated code uses translators.py, binary.py, and aisstring.py which should be packaged with the resulting files.

Requires:

Author: xmlbinmsg

Version: 4791

Status: under development

License: Generated code has no license

To Do: FIX: put in a description of the message here with fields and types.

encode(params, validate=False)

source code 

Create a ris_waterlevel binary message payload to pack into an AIS Msg ris_waterlevel.

Fields in params:
