From 0f8aedbe9492a5226fddd4ad27dae21b8a39e1b4 Mon Sep 17 00:00:00 2001 From: Michael Sevakis Date: Sun, 2 Dec 2012 01:09:44 -0500 Subject: [PATCH] Add a true waveform display to the oscilloscope plugin. * Adds some additional niftyness like a floating popup display that is implemented in an OSD library for use by other plugins. * Speed changes are now gradual for both views and follow a curve derived from some fiddling around to get a nice feel. * Refined a few behavioral things overall. It needs a bit of help from a direct PCM channel callback so it may capture PCM for waveform display. Also need a few other core routines to help out for the OSD. Messes with some keymaps. Some targets need keymaps to access the different views. Some devices can't support the additional view because it requires a large buffer ( > 1 s) for samples. If the plugin buffer is small, they can still use the popup display since the plugin is also much smaller in that case. Slow speed waveform needs some refining so it draws gradually like a real oscilloscope but I'll stick with what it is, for the moment.
