Component Viewer

The Component Viewer window shows static information and helps to analyze the operation of software components. The required infrastructure can be easily added to user applications and is already implemented in the MDK-Middleware and Keil RTX5.

Refer to the Component Viewer documentation for detailed advice on how to show information from user software using using an SCVD file. The same SCVD file allows also to annotate event information for the Event Recorder.

The Component Viewer shows information about:

  • Information from software components that is provided in memory for example by static variables or structures.
  • Objects that are addressed by an object handles or dynamic arrays.

Watch Window ButtonComponent Viewer windows containing objects are listed in the menu View – Watch Windows.

The menu entries are visible when you have enabled and added files with Manage Component Viewer Description Files.

The picture below is an example showing debug information for an USB Device object:

Component Viewer

In case the Component Viewer Description File contains specifications that cannot be located in the program code, then the Component Viewer shows information about the origin and the identifier that is missing.

The picture below is an example showing information about a missing network component.

Missing Components

This application is not using a network component, so remove or disable the file in Manage Component Viewer Description Files.
