- Add GMLAN 29bit filtering feature. In addition to J1939 matching, it is now possible to match DBC messages using only the Arbitration Id (bits 14-26 of CAN Address), since Priority id (higher bits) and Sender Id (lowest 13 bits) are not relevant when interpreting the CAN message content. This allows to use the excellent GM Global A DBC files on https://github.com/commaai/opendbc. Just remember to select the "GMLAN" matching criteria on DBC File manager.
- Add "Filter labeling" feature. Using loaded DBC files, it matches the filter Ids with DBC messages and shows them in filter windows. Labeling works in the main window (no need to set "Frame interpret" on, since this is a separate feature), as well as in Flow view, Frame data analysis, Playback and Fuzzzing windows. This makes it so much easier to concentrate on those CAN messages that matter. To use this feature, select global "Label filters using messages from DBC files" on Main Configuration page, and then enable the feature on individual DBC files (on DBC file manager) as needed. This is needed if there's overlap in CAN addresses between DBC files, and because the filter labeler cannot tell apart anymore which Filter ID is associated to which bus, it might label them incorrectly. But usually it's ok to just enable the labeling with all the DBC files.
- In Frame data analysis window, in addition to J1939 decoding show also GMLAN (Priority bits, Arbitration Id, Sender Id) decoding.
- FilterUtility static class used for centralized ListWidgetItem creation and for other helper functions
- DBC handler: To allow setting bus numbers even before connection is configured, do not enforce "valid" bus numbers
QtCanBus is not limited to SocketCAN, it also supports various
Windows CAN adapters directly.
Also, add the term Connection to describe the inheritance
hierarchy better.
QScintilla was *EXTREMELY* overkill for what I really needed. It also
created problems for people trying to compile the source. The new
solution is much easier to compile and use.
switched to using system QTScintilla library on Linux. This prevents
you from needing to compile it yourself, added preliminary support for
three buses with a GVRET device (for Macchina M2 boards)
In FlowView:
- Drastically improved functionality of live mode. It actually works now
- Fixed several crash bugs
- Program didn't used to pick up new frames properly. This is now corrected.
In Graphing window:
- Fixed dynamic updates to work properly even under heavy bus loads
In frame playback:
- Fixed a bug where single stepping through frames didn't send them over canbus
much more object oriented and encapsulated. The biggest addition is
that it is now possible to support multiple DBC files being loaded at
once with each file associated to one or both buses. Note that
currently the program still does not support multiple DBC files but
the groundwork is there.
refactoring of some DBC code, fixed some DBC calcs, fixed a bug in the
frame playback window, incremented version number to show that a lot
has been done.
