CPU Load View

[Example FreeRTOS+Trace Views]

Visualises

The processing load on the CPU with respect to time.


Synopsis

Time is displayed on the horizontal axis. The CPU load is displayed on the vertical axis. Colours are used to indicate the actors that were running at any particular time (in this case, actors are both FreeRTOS tasks and interrupts).

Just as in the main trace view, dragging the mouse adjusts the zoom level. The graph resolution (or granularity) is adjusted using the "Resolution" menu. A higher resolution is more sensitive to spikes in the CPU load, while a lower resolution makes overall trends easier to view.


Click Events

The name of an actor is displayed when the corresponding colour is clicked on the graph.

Double-clicking in the graph shows the corresponding interval in the trace view.
