+apple ~macintosh
Find rows that contain the word 'apple', but if the row also contains the word 'macintosh', rate it lower than if row does not. This is "softer" than a search for '+apple -macintosh', for which the presence of 'macintosh' causes the row not to be returned at all.

How to Access CAN Signals with a Script?

Last updated: 2019-01-21
Question:
How to access CAN signals with a script?
Answer:
It is not possible to get the value of a CAN signal directly because unlike CCP/XCP the CAN protocol does not support this.

There are two options:

The first possibility: Using the keyword "mbuffer[x]" in the script.
"mbuffer[x]" returns the measurement value of the object from the location specified (index). The last measured value gets the index 0.
Devicename.CAN_Signal.mbuffer[0];

The second possibility: Using a global variable as a buffer and a function:

  • define a global variable
  • create a function that receives the value of the CAN signal and assign it to the global variable.
  • measure this variable and insert this function into the measurement list (under "function").
