OSCILLOSCOPE 2
--------------

Analog oscilloscope with standard X/Y beam control. By driving the X control by an external oscillator, Lissajous figures can easily be generated. To monitor a stereo or multiple signals you can overlay more oscilloscopes, by setting background, cross and grid colors to "0" in all but the bottom most module.

NOTE: With respect to Oscilloscope, Oscilloscope 2 uses a different rendering method always displaying continuous plots, while Oscilloscope displays only one point per sample. There is however a limit as for how long phosphor persistance can be set: phosphors will fade off completely after exactly one block of samples (both scopes sample the input signals at a rate of 30 Hz) and can't be made lasting longer; an Erase pin is therefore no longer necessary. You are free to choose which Oscilloscope best suits your needs depending on your specific application. 



PIN DESCRIPTION

 -[GUI] BG Top/BG Bottom/Plot/Grid ARGB: standard ARGB hexadecimal strings to specify the 32 bits color of the
                                         respective elements. To prevent an element being drawn simply set its color
                                         to "0" (i.e the alpha channel will be zero too)

 -[GUI] X/Y Range (V): useful range in volts for X and Y controls respectively
                       NOTE: the internal sawtooth oscillator has a fixed range of -10/+10, therefore always set X
                       Range to 10 when using X Source = Internal unless you have a particular reason not to

 -[GUI] Beam Size: beam size in pixels

 -[GUI] Backwards Beam: enables/disable plotting of beam going backwards. It is advisable to disable it when using the
                        internal source, to make horizontal lines invisible, and to enable it when drawing Lissajous
                        figures

 -[GUI] Persistance (0/1): phosphor persistance, from 0 (no persistance) to 1 (fading lasts a whole 30 Hz sampling block)

 -Input X/Y: audio inputs for beam control. Useful range (corresponding to the box edges) is -Range to +Range as specified
             by the apposite pins

 -X Source: specify whether X beam position is driven externally (Input X) of by the internal sawtooth oscillator

 -X Internal (Hz): frequency in Hz of the internal sawtooth oscillator
