A trace is a low-level logging mechanism that can be used to interpret a system state during execution. Analyzing traces for microcontroller-based applications using FreeRTOS can save embedded engineers significant time and energy when troubleshooting unexpected behavior. Utilizing the Tracealyzer tool with a FreeRTOS application requires a simple integration of the TraceRecorder library to capture traces. Traces can be recorded and saved with snapshots during program execution, or streamed in real-time.
