In the sea of automotive bus data, we often capture a huge number of messages and signals. However, how to quickly mark, locate and interpret those critical events in these fast-scrolling data streams has become a major challenge for engineers. For TSMaster Bus Analysis module, I have compiled 7 related practical tutorial articles for you. In this issue, we will unlock the [TSMaster Bus Analyzer 1] - Real-time annotations in the graph of the use of skills.

1. The role of real-time annotations
Before we get into tips on using real-time annotations, let's understand what a real-time annotation is and what it does.
Real-time annotation is a function used in graphs, which is mainly implemented by placing a vertical cursor as a marker in the graph window in real time. The marker can not only annotate and locate the signal sampling point in real time, but also record it in the blf file, so that we can easily view the corresponding signal point at the annotation.
2. Tips for using real-time annotations
1. Directly annotate as follows:
(1) Create a graphical module by clicking the right button to import signals for observation.
(2) Start the project, click the live annotation icon in the analysis and perform live annotation, you can see that the live annotation cursor has been hit on the graph at this time.
(3) Click on the live annotation bar in the graph to see the annotated cursor and its timestamp, and click on the cursor option to locate the time point of the live annotation for easy observation.
2. Use the script to automate annotations as follows:
(1) Create a graphical module by clicking the right button to import signals for observation.
(2) To write a script for automated commenting, first create a callback event, then write the comment condition in the event, and then use the app.write_realtime_comment() function to complete the automated commenting implemented in the script.
(3) Start the project and start the script, observe the graphic window, and find that when the signal value reaches the judgment condition in the script, a real-time annotation will be performed, and the automatic annotation effect is achieved.
3. The use of real-time annotations in recording and playback proceeds as follows:
(1) First of all, we implement the automatic annotation according to the method of automatic annotation, then we start the project and turn on the bus record.
(2) Stop the project, add the recorded blf file to the bus playback, we use offline playback here to facilitate rapid observation of the recorded graphics, playback is complete, open the graphics window, click on the real-time comments column, found that the real-time comments are also synchronized back to the blf file, so that we can record the direct location of the signal sampling point to view.
(3) If there is no real-time annotation in the record, then we can also synchronize the annotation to achieve the same effect in the playback, first of all, it is also the first script to achieve automatic annotation, and then playback, you can see that it also achieved with the real-time annotations recorded to the same effect in the blf file (the following chart).
