Release 3.4.0

Changes

• new graphical user interface :

  • visualize channels
  • exposes library functionality for single files (convert, export, cut, filter, resample) and multiple files (concatenate, stack)
  • requires pyqtgraph

• added mf4 demo file creation example
• added Matlab v7.3 export
• added iter_get method
• added configuration option to return single bit channels as bool
• preserve bit count for unsigned channels with bit count <= 4
• lib: for plain CAN bus logging add channels from database when saving

Fixes

• fixes for mdf v4 channel conversion from keys

Release 3.3.1

Fixes

• fixes #58
• fixes for VLSD BYTE_ARRAY channels

Changes

• removed __slots__
• do not expose MDF2, MDF3 and MDF4 classes on asammdf import to encourage the use of MDF class

Release 3.3.0 (proper)

• fix for Signal interp if the new axis is empty
• fix export in case of bytearray channels
• fix nested structure composition
• fix error in plot method

Changes

• use XML parsing for comments
