The events affecting a queue or semaphore over a period of time.
Kernel objects used for inter-process communication (IPC) include
FreeRTOS queues and the various types of semaphore.
An IPC event is an event that changes
the state of an IPC object, such as a queue read, queue write, queue peek,
semaphore give or semaphore take. The kernel object history view shows
the IPC events that affect a particular IPC object over a period of time.
The trace view corresponding to the time at which an event occurred is
displayed when the event is clicked in the kernel object history view.
Send events that correspond to a receive event, or receive events that
correspond to a send event, are located using the buttons on the right
side of the view.
