((BETTER)) Download Asammdf

If you want to review data from e.g. 20 MF4 log files from your CANedge, simply concatenateand DBC-convert them via the asammdf GUI. From here, you can create quick visual data plots (incl.calculated fields), filter the data in the column style 'tabular view' or export to e.g. CSV/MAT for furtheranalysis.

If you're using a CANedge2 (WiFi) orCANedge3(3G/4G) to auto-push your MF4 log files to an S3 server, you can use an S3 drive tool to map your S3bucket as a local network drive. This in turn lets you easily drag & drop files into your asammdf GUI - asif they were stored locally, enabling quick and seamless analysis across a fleet of devices.

The asammdf GUI is designed for cross-platform ad hoc analysis of CAN bus data. It can be quickly installed on aWindows/Linux PC either via the pre-built GUI executable or by installing via pip. It is a usefulgeneral-purpose tool for analysing and visualizing both raw and DBC decoded CAN bus data.

However, asammdf is not designed for visualization of CAN signals in your browser. For this purpose, see insteadour intro to telematicsdashboards, where we show how to use our MF4 Python API to set up free open source browser dashboards tovisualize your CAN data.

This depends on your use case and preferences. For some users, asammdf will be more than sufficient - while forothers, it may be necessary or more practical to use e.g. CANalyzer or other existing tools.

The asammdf DBC functionality utilizes the popular canmatrixlibrary and supports most of the DBC functionality - e.g. complex multiplexing, J1939 PGNs, OBD2 etc. It doesnot support conversion of multi-frame packets.

The asammdf GUI lets you visualize raw CAN data, meaning that you'll be able to view and analyze the raw CANframes involved in ISO-TP (Transport Protocol) communication flows. This can be useful for e.g. identifyingrequest frames, first frames, flow control frames and consequtive frames for later analysis.

The asammdf GUI does not, however, support e.g. linking together multiframe responses from e.g. UDS (UnifiedDiagnostic Services) or J1939ISO-TP. For this purpose, you can however use our MF4 converters to convert yourraw log files to e.g. Vector ASC (for processing in CANalyzer), or you can use our MF4 Python API to process transport protocolcommunication (incl. UDS and J1939 transport protocol examples).

Yes, asammdf lets you load raw LIN bus data and show it in a 'tabular display' to analyse the raw LIN frames.Further, you can create a LIN DBCfile to decode the raw LIN bus frames into human-readable form (physical values). Typically you wouldconstruct a LIN bus DBC file based on a LINDescription File (LDF).

The asammdf GUI/API is one of the possible tools for use with the CANedge (see also our MDF4 converters for fullinteroperability). In many ways, the asammdf GUI is like the SavvyCAN 'interpret' functionality, but just withextendedfeatures (e.g. better graphical plots, more extensive DBC features, more exports etc).

Further, the asammdf API enables easy programmatic processing of log files, which is a big advantage in theCANedge vs. the CLX000 - and means that it's possible to process data automatically and at scale. In addition,for the CANedge2, the S3 Python API can be used together with the asammdf API to set up advanced use cases. Forinspiration, see our API examples on github.

We do not contribute directly to asammdf, except for a few small tweaks (e.g. to support MDF4 data from theCANedge natively). We do however actively provide suggestions and feedback to the asammdf team based on userinputs.

When I read from an mdf (.mf4) file with asammdf (Python 3.7), as soon as the sample count crosses a barrier, the timestamps start counting up from close to 0 again, like an overflow :for 3 files exactly at 29045 lines, one file at 27234 lines for some reason. This means that when I use methods like resample or to_dataframe that the interpolation that occurs during these methods royally screws up and I get botched data.

I found out that the trouble was actually caused by the asammdf library (somehow). I can't really point out which version caused the problem because I updated all libraries - and it worked afterwards. Currently I'm running on version 5.13.13 and there's no more trouble reading the timestamps correctly.

Hi I am using asammdf library for handling MF4 files. When I open the file using asammdf GUI , in Info tab I can see information . I am trying to extract the same info by calling .info() function on the same file as below.

The error comes from line 2097 in mdf_v3.py (source file to asammdf library). However, if I do not convert the version to 3.00, and keep the default 4.10. Then there is no error, and the conversion happens without any error.

I installed recently Anaconda and need to use asammdf.Standard was 5.8.0 installed, I need 5.21.0.Running the installer from -forge/asammdf did not update the package.Then I installed a new environnement and asammdf and dependencies from scratch. So I could get 5.19.16 installed, but still not the latest.
