Parse Module

This module is primarily responsible for providing a high-level interface for parsing CANOpen messages according to Object Definiton files or Electronic Data Sheet files, provided by the end user.

class canopen_monitor.parse.CANOpenParser(eds_configs: dict)

A convenience wrapper for the parse function

get_name(message: canopen_monitor.can.message.Message) → Optional[str]

parse(message: canopen_monitor.can.message.Message) -> (<class 'str'>, <class 'str'>)

Detect the type of the given message and return the parsed version

@:param: message: a Message object containing the message

str: The parsed message

class canopen_monitor.parse.DataType(value)

An enumeration.

class canopen_monitor.parse.EDS(eds_data: [str])

canopen_monitor.parse.load_eds_file(filepath: str, enable_ecss: bool = False) → canopen_monitor.parse.eds.EDS

Read in the EDS file, grab the raw lines, strip them of all escaped characters, then serialize into an EDS and return the resulting object.

Parameters

• filepath (str) – Path to an eds file

• enable_ecss (bool, optional) – Flag to enable ECSS time, defaults to False

Returns

The successfully serialized EDS file.

Return type

EDS

canopen_monitor.parse.load_eds_files(filepath: str, enable_ecss: bool = False) → dict

Read a directory of OD files

Parameters

• filepath (str) – Directory to load files from

• enable_ecss (bool, optional) – Flag to enable ECSS time, defaults to False

Returns

dictionary of OD files with node id as key and OD as value

Return type

dict
