(csv) Export from ISO-TP Decoder....

[Mr-MIBonk]

Thank's a lot! But i think there is somesthing wrong... my original full CAN Log file is raound About 6MB, after iunselected some Frames the Export File is larger den 4GB(!) and i can't open it yet in Texteditor because it is to large. I think the different between 6MB input and 4GB output looks like some issue in export functionaly.

I also did a quick test and it seems to me that the feature works as intended, but it may not be what you expected.

A small 413k binary trace (blf type) produces a 339966k text file (size factor about 823). The reason for this is how the data is interpreted and written to the text file.

You could try to reduce the size by deselecting the IDs you are not interested in, or maybe you should be more precise about what you expect as output?

Example output:

However, there seems to be a small problem with the decoding of the diagnostic session control response. According to ISO14229-1 the sessionParameterRecord[] is defined as [ P2Server_max (high byte) P2Server_max (low byte) P2*Server_max (high byte) P2*Server_max (low byte) ] which converts to a P2MAX (Max Wait / Resp Time) of 50ms and a P2 Ext MAX of 4000ms.

Yes, the file size is going to be pretty large because it outputs as much about the UDS messages as it can. So, some messages expand a lot.

As for the bug, yes, there is probably something to that. I always thought that the values looked a bit odd. I'll have to look at that.
