Debounce | SuperCollider 3.14.0-dev Help

Description

Debounce is intended for cleaning up incoming signals from e.g. Arduinos that represent switching buttons. Such buttons often produce occasional wrong values, reporting e.g. off when the switch is on. Debouncing filters such signals, requiring at least e.g. 5 positiv values before actually switching to on.// onFunc runs when on condition is reached, onFunc when off. Size is the number of sequences in a row before triggering. d = Debounce({ "on!".postln; }, { "off...".postln }, 5); d.set(1).lastN; // run this several times until on d.set(0).lastN; // ... and off d.size = 8; // change size of lastN d.set(1).lastN; // run this several times until d goes on. d.size = 5; // simulate input from arduino Tdef(\deb, { var dt = 0.03; inf.do { 30.do { d.set(1); dt.wait; }; "crackly on ".postln; rrand(1, 10).do { d.set(2.rand.postln); dt.wait; }; 30.do { d.set(0); dt.wait; }; "crackly off ".postln; rrand(1, 10).do { d.set(2.rand.postln); dt.wait; }; }; }).play;

Class Methods

Debounce.new(onFunc, offFunc, size: 5)

Arguments:

onFunc	a function that runs when on condition is reached
offFunc	a function that runs when off condition is reached
size	the list of how many lastN values to keep
