Main prototype and parameters

void CrcLib::StopEverythingFromError(const Note notes[], const ColorDuration colors[])

The following parameters must be passed to the function for it to work properly:

A sequence of notes to play repeatedly (use it to distinguish from other errors)
A sequence of colors to display repeatedly

Overloads

This function does not have any overloads. It can only be used as described by the main prototype.

Examples

#include <CrcLib.h>

// See the page about Note and ColorDuration
// Define some color pattern using { <duration in ms>, <color> }
ColorDuration pattern_error[] = { { 250, Color(213, 4, 30) }, { 250, NO_COLOR },
    { 1000, BLUE_LOW }, ColorDuration::END };
// And some song using { <duration in ms>, <note frequency in Hz> }
Note notes_error[] = { { 250, NOTE_B4 }, { 500, NOTE_F5 }, Note::END };

void setup() {
    CrcLib::Initialize();
}

void loop() {
    CrcLib::Update();

    if (2 > 1) { // some terrible, unforgivable error
        CrcLib::StopEverythingFromError(notes_error, pattern_error);
    }
}
