System Viewer windows display information about peripheral registers. Use the System Viewer to:
- View peripheral register property values.
- View additional information about a property (red circle).
- Change property values at runtime. Click into the value-field and enter a new value.
- Search for specific properties using the search field. Enter TR1 Regular Expressions to narrow the selection and press ENTER. For example:
Regular Expression Output .*[0-2] Returns properties that end with a number between zero and two. .*CCR* Returns properties that contain the string "CCR".
Open System Viewer windows from the toolbar or from the menu View – System Viewer.
The picture below is a collage showing various value representations.
Note
- Silicon vendors provide CMSIS-SVD files, which describe the device peripheral registers. These files can be used for adding System Viewer windows to a project.
