vemslog format
« on: March 02, 2012, 02:39:55 pm »
I would like to have Matlab scripts processing my vemslog records.
Does someone know about the vemslog format?
I know I can convert .vemslog to .csv text format but I need direct access for batch command.
Thanks

Nobody answered this question. But I think it is a good one. I also want to process my vemslog files with other tools. gnuplot for example. That way i can do consistent log file analyzing. And don't have to setup my vemslog viewer with every new version. Also printing things to pdf is easier for example.

vemslog to csv conversion is not good enough. It seems not to convert all channels to csv. And it is not real csv at that. It is tab separated not comma separated.

Is there more vemslog information available? I can not find it on the wiki. Or can someone build a better csv converter.

Vems is a nice ECU. but at the logging side of things it misses a lot of features.

there is a header saying that the bin is by 512kB chunk. I came to understand that the data list is depending on the config options and fw version, so only vemstune can decipher. At least there should be a vt option to save a flat data bin with header telling the format
