Canoe- how to parse messages and display information in the trace window (use of program node and structure type system variables)

If I want to Trace Window to parse a specific message , And display the information in Trace window , What to do ？

Program Node

If you read the article 《CANoe-Measurement Setup》, You should know Trace Where does the data in the window come from , Where to set up

We can regard the flow direction of data as the flow direction of water , To receive and purify water, a purifier shall be set on the path of water flow , Same thing , You want to receive and parse the data , And then it shows up in Trace On the window , It also needs to be From data sources to Trace Between window modules Insert a “ Purifier ”, We call it Program Node

Program Node, Programming nodes , It is Measurement Setup A function block in , Its purpose is to add or reduce the data of the data source , Or analyze the data

Pay attention here , after Program Node Processed and rendered data , Not the actual data on the bus , It depends on how you handle it , It's increased , Still reduced , Or you just forwarded it intact

Programming nodes are essentially through CAPL The script processes the data , How to deal with that ？

Data flows from the data source to Program Node when , If the programming node does nothing , Will be blocked here , Will not pass Program Node Flow to right . This is different from other function blocks , Be careful

Program Node, It is necessary to receive and forward the flowing message

We know , Programming nodes are essentially through CAPL Script to data
