In this section:

What do you want to do?

The Timeline window is available from the C-SPY driver menu during a debug session.

DataLogGraph_win_Qt_01.png

This window displays trace data represented as different graphs, in relation to a shared time axis.

The Data Log graph displays the data logs collected by the trace system, for up to four different variables or address ranges specified as Data Log breakpoints.

Note

There is a limit on the number of saved logs. When this limit is exceeded, the oldest entries in the buffer are erased.

Requirements

One of these alternatives:

  • The C-SPY simulator. (Not for all cores and devices.)

  • A device and a debug probe that either supports ITM and SWO, or supports delivering ETM and ITM trace concurrently.

Display area for the Data Log graph

Where:

  • The label shown at the top left of the graph area displays the variable name or the address for which you have specified the Data Log breakpoint.

  • The graph itself displays how the value of the variable changes over time. The label area also displays the limits, or range, of the Y-axis for a variable. You can use the context menu to zoom. The graph is a graphical representation of the information in the Data Log window, see Data Log window.

At the bottom of the window, there is a shared time axis that uses seconds as the time unit.
