I am writing a simple logic analyser interface. So far it can - set the trigger method - set the number of samples befor and a after the trigger point - start and cancel capture - set the origin and span of the displayed data (two sliders) I will probably add - hairlines, with display of their time and distance - average frequency calculation Anyone got tips for features that should be in a simple logic analyser, or examples of good user interfaces?
