Event Recorder

µVision debugger tightly integrates the Event Recorder component providing high visibility into the run-time operation of complex software systems.

About Event Recorder

Event Recorder is a software component supplied in the Keil::ARM_Compiler pack that is part of the MDK installation. The Figure below illustrates the operational concept of the Event Recorder.

Event Recorder provides an API (function calls) for event annotations in the application code. These functions record events along with timestamps and additional information. The data is stored in the event buffer located in the RAM of the target hardware. Refer to Event Recorder: Theory of operation for further details.

The µVision debugger reads the content of the event buffer and displays it in the Event Recorder window. The graphical display over time is available in the System Analyzer window.
