Trace View

[Example Tracealyzer Views]


The execution pattern of FreeRTOS tasks, interrupts and events with respect to time.


The trace view shows task scheduling, interrupts and events against time.

Time is shown on the vertical axis. Tasks are shown in the left trace column. Interrupts are shown in the right trace column. Indentation within a column shows task or interrupt pre-emption. Actor names are shown on the left side (in this case, actors are both tasks and interrupts). Labels show kernel calls and user events.

Click Events

Mouse events are described on the Trace with Zoom page.
