1 month ago I've made some changes in the development branch. You can provide the raw argument as a dict:
- it must contain the key
__default__ - the key are the channel names, and the values are the individual raw states

I need to read specific signals from MDF file, but some signals should be read as raw. I know in advance which signals should be read as raw. It seems that
rawparameter into_dataframeaccepts single value and not value for each of specified signal. Is there some way to achieve that some signals are read raw while others not?My approach is to create new
MDFwith usingappendin a loop for wanted signals which are retrieved withgetwith specifiedrawparameter. After retrieving I putsignal.raw = Falseand append. At the end I useto_data.frameand this approach seems to work, but its 'hacky' way of doing it. Is there maybe more straightforward and clear way?
