Events Filtering

Using the Event Recorder filter you can select event levels to be recorded per each software component. 

To access the filter configuration in µVision - stop the debug session and click on the filter button (Event Recorder Filter Button) in the Event Recorder window. This will open the following dialog:

Event Recorder Filter

Where

Record Component Events Hierarchical list of software components with associated component events. Unspecified Events lists memory areas not covered by software components.
Error Enable or disable the recording of errors reported by an event function.
API Enable or disable the recording of events triggered by an API function.
Op Enable or disable the recording of events triggered by an operation.
Detail Enable or disable the recording of events triggered by detailed operations.

The dialog has tri-state controls. If a control is grayed out, then the parent item settings or default settings are active.

The settings are stored in the target of the project. To keep your configuration unchanged after a reset, place the Event Recorder into a non-initialized memory area. Refer to Setup Event Recorder.

The current filter settings can be also saved and restored on the host computer using the Event Recorder debug commands.  


Note

  • The Event Recorder software component also provides API functions such as EventRecorderInitialize, EventRecorderDisable, EventRecorderEnable that can be used throughout the application code to configure the events filter. When such API calls are executed, the current filter configuration gets updated. And vice versa - the changes made through the Event Recorder filter dialog will overwrite the filter settings previously done with the API.

Filtering Event Statistics

The Event Recorder filter has a special category (0x80) for the Start/Stop Statistics events. In this category, the event levels (Error, API, Op, Detail) correspond to the statistics groups (A, B, C, D) as shown on the figure below.
