This is a library for importing and parsing data from Kvaser CAN files when you don't have a DBC file. The code should be fairly simple and self-documenting, and all other information should be contained within this file. You can install the library on pip via pip3 install canLogParse.
Takes a raw, unformatted CAN packet and returns it in a more useful format. The possible formats are array (the default), tuple, and dict.
The data is structured as follows:
leadingZero: The zero at the start of the packet.
id: The packet ID.
dataLength: The number of data bytes.
data: The data bytes in an array of strings.
T/R: It is assumed that this is transmit/receive, but so far it has only been observed as R.
timeStamp: The packet timestamp.
In array and tuple formats, the data is in the order above. In dict format, the keys are as stated above and
Parses an array of CAN packets in the same way as parseCanPacket. Formats are the same as parseCanPacket, but put together in an array.
The same as parseCanData, but taking the data from a file.
Takes a 2D array (or array of tuples) of packets, returns a list of all unique packet IDs.
Takes a 2D array of packets and writes the data in CSV format to the specified file.
This function takes the given data and formats it in the specified way.
_formatPacketList(leadingZero, id, dataLength, data, tr, timeStamp), _formatPacketDict, and _formatPacketTuple
These functions take in the packet data and format it into either a list, a dictionary, or a tuple.
This function takes a packet array and returns the data bytes as an array of strings. It does this by removing all known non-data bytes, which is a terrible way to do it. This function should be updated to extract it using the included dataLength byte.
This takes a file name, and returns its rows in a list.
