CONFIG_PERCEPIO_RECORDER_TRC_CFG_NEVENTGROUP

Number of Event Groups

Type: int

Help

These define the capacity of the Object Property Table, i.e., the maximum
number of objects active at any given point, within each object class (e.g.,
task, queue, semaphore, ...).

If tasks or other objects are deleted in your system, this
setting does not limit the total amount of objects created, only the number
of objects that have been successfully created but not yet deleted.

Using too small values will cause vTraceError to be called, which stores an
error message in the trace that is shown when opening the trace file. The
error message can also be retrieved using xTraceGetLastError.

It can be wise to start with large values for these constants,
unless you are very confident on these numbers. Then do a recording and
check the actual usage by selecting View menu -> Trace Details ->
Resource Usage -> Object Table.
