DataTips provide a convenient way to view information about variables in your program during debugging. DataTips work only in break mode and only with variables that are in the current scope of execution.
In Atmel Studio, DataTips can be pinned to a specific location in a source file, or they can float on top of all Atmel Studio windows.
To display a DataTip (in break mode only)
-
In a source window, place the mouse pointer over any variable in the current scope. A DataTip appears.
-
The DataTip disappears when you remove the mouse pointer. To pin the DataTip so that it remains open, click the Pin to source icon, or
-
Right-click on a variable, then click Pin to source.
The pinned DataTip closes when the debugging session ends.
-
To unpin a DataTip and make it float
-
In a pinned DataTip, click the Unpin from source icon.
The pin icon changes to the unpinned position. The DataTip now floats above any open windows. The floating DataTip closes when the debugging session ends.
To repin a floating DataTip
-
In a DataTip, click the pin icon.
The pin icon changes to the pinned position. If the DataTip is outside a source window, the pin icon is disabled and the DataTip cannot be pinned.

Place the mouse pointer over a DataTip, and then click the Close icon.
