Tracing allows recording the software behavior during runtime for later analysis of collected trace data. Tracing is especially important for systems integrating an operating system (OS), like FreeRTOS for embedded systems. FreeRTOS feature is multi-threading – the ability to run multiple programs (threads) on a single processor core by rapidly switching among execution contexts. Multi-threading, however, makes software behavior more complex, and gives the developer less control over run-time behavior as execution is preempted by the scheduler.
If you need to make compact data from various inputs here is an example:
This example shows how to extract data from a given file and store it in a queue, on one side, and on the other hand, collect the receiving data with an analysis TLM FIFO.
