How to define critical sections for the trace recorder?
Oct 27, 2014
Our Tracealyzer versions for microcontroller RTOS uses Percepio’s own recorder library, which uses separate definitions for critical sections within the recorder.
Why do I get “error: ‘uxPendedTicks’ undeclared”?
Mar 6, 2014
If you get this error when compiling the recorder, you are probably using an older version of FreeRTOS (v7.5.x or earlier) together with a newer version of the recorder library.
How much RAM does the trace recorder need?
Oct 19, 2013
RAM requirements for Percepio’s recorder library when used with FreeRTOS, OpenRTOS, SafeRTOS and Micrium µC/OS.
How do I enable tracing of interrupt handlers?
Oct 17, 2013
How to enable tracing of interrupt handlers with Percepio’s recorder library when used with FreeRTOS, OpenRTOS, SafeRTOS and Micrium µC/OS.
What does the label “ISR #1” mean?
Oct 16, 2013
You need to set a name for the ISR using vTraceSetISRProperties, otherwise the numeric ID stored using vTraceStoreISRBegin is displayed.
What does the label “ISR using …” mean?
Oct 15, 2013
Add vTraceStoreISRBegin and vTraceStoreISREnd calls to your interrupt handlers.
How do I set custom names for queues (and other kernel objects), instead of the default names (“Queue #1” etc.)
Oct 14, 2013
Examples of setting custom names for queues and other kernel objects using vTraceSetQueueName, vTraceSetSemaphoreName or vTraceSetMutexName.
