asammdf v7.1.1 GUI: Various suggestions

[MatinF]

Hi Daniel,

I've listed below a number of observations on v7.1.1 of the GUI (Windows 10, Python 3.8):

Export settings are too slim

Recommend expanding these slightly to avoid overflow:

Bus Logging uses LIN DBC as default

Recommend switching to CAN DBC as default, as that will be the use case for 99% of users

Graphical plots are not correctly "synced" to the data

In 7.0.7, adding a new plot would auto sync the plot around the data. Currently, the result is as below when initially plotting:

The interpretation of J1939 PGNs seems to differ in 7.1.0/7.1.1 vs. 7.0.7

I get 136 unique CAN IDs reported in the Bus Logging tab in 7.1.1 vs. 100 unique CAN IDs in 7.0.7. I've sent you a data sample and DBC.

please try the development branch code

Thanks Daniel, that seems to fix most of these.

Remaining observations:

CAN ID difference

There is still the ID discrepancy between 7.0.7 and 7.1.1, I believe it's due to the fact that 7.0.7 filters out the CAN IDs that do not contain valid signals.

For example, in the sample data I've sent you, the CAN ID 0xCF00400 contains the valid EngineSpeed signal as you'll see if you plot it. In contrast, the CAN ID CF00421 contains purely 0xFF values in the payload and should be filtered out based on the default 'Ignore invalid signals' rule that is to be applied under J1939 (as is the case in v7.0.7).

CAN IDs shown when double clicking J1939 signal is the DBC ID, not "real" CAN ID

Due to the PGN matching logic of J1939, the CAN ID found in the DBC may not equal the actual CAN ID. In troubleshooting, it's useful to be able to "go back" into the raw bus logging file and look up a specific CAN ID based on a converted signal. Double clicking the signal allows a user to see the underlying CAN ID, but it's the CAN ID from the DBC file - not the actual CAN ID resulting in that signal.

As an example, EngineSpeed in the sample file I sent you shows the CAN ID from the DBC below. Ideally, it would have shown CAN ID CF00400 instead.

Another observation:

The 'crosshair' in plots is white, which is not ideal for white background plots

See below example:

[MatinF]

One other comment: When displaying hex format CAN IDs in the tabular display, the default pre-padding is always as if the CAN ID is 29 bit. I suggest that when working with 11 bit CAN IDs, the padding changes accordingly. Alternatively, I sugges tentirely removing zero padding in front of the CAN IDs.

Another observation:

The 'crosshair' in plots is white, which is not ideal for white background plots

See below example:

The cursor is now configurable form the menu (Settings -> Cursor)

Ok thanks Daniel, if possible it would be great if the default can be set to a color that can work both for black/white themes

any sugegstions?

[MatinF]

I suggest #e69138

[MatinF]

The update to the crosshair colors solved that issue, thanks Daniel.

I think the main issue remaining are:

1. J1939 'Ignore Invalid Signals' does not seem to work - invalid signals are not removed (7.2.0.dev2)

2. Clicking a cell in the 'tabular display' causes asammdf to stall and crash on my end (7.2.0.dev2)

3. Tabular display filters do not seem to work correctly, e.g. filtering 11-bit IDs to show all IDs above "700" does not work in 7.2.0.dev2 (but works in 7.1.1)

Just an update on 2. above, I believe I've isolated the issue further as outlined here:
#751

[MatinF]

Update:

I believe the filter issue has been resolved in the latest update. I'd still personally prefer that 11-bit IDs would not have the full 29-bit 0-padding in front, but that's more of a matter of taste than critical.

Since we've discussed the tabular cell issue separately, I believe we can 'pause' that for now and see if we may get some inputs from the pyqtlet2 team.

As such, only remaining item here is the J1939 invalid signals.

The J1939 invalid signals issue has been resolved in latest dev
