EnvelopeGenerator

Generates dynamic envelopes with N positive integer points

• void initEnvelope(unsigned short int* points, unsigned short int* ticks, byte numberOfPoints)

  • Dynamic envelope generator
  • Pass "numberOfPoints" number of elemnts via the array of "unsigned short int points"
  • Pass "numberOfPoints" number of durationsPerPoint via the array of "unsigned short int ticks"
  • "points" an array of Envelope points, the output will wrap around from the last point to the 1st automaticly
  • "ticks" an array of time ticks PER point. This essentialy gives you a way to scale each point and the speed/gradient of the curve

  envelopeGenerator envelopeOne;
  const byte numberOfPoints = 4;
  unsigned short int points[numberOfPoints] = {0,10,20,5};
  unsigned short int ticks[numberOfPoints] = {30, 30, 30, 30};
  envelopeOne.initEnvelope(points, ticks, numberOfPoints, 0);

• unsigned short int getEnvelope(unsigned short int frameCounter)

  • Generates your curve based on your point list and time blocks using "frameCounter" (internal variable) as the time index
  • "envelopeOne.envelopeBandwidth" can be used to limit your frame counter and keep it in bounds of your dynamic frame ticks

  while(true)
  {
   Serial.printf("\r\n%d", envelopeOne.getEnvelope(envelopeOne.frameCounter));
   envelopeOne.nextFrame(1);
  }

  The above generates this:

  

OneShot Envelopes

Set up

  envelopeGenerator envelopeOne;
  const byte numberOfPoints = 2;
  unsigned short int points[numberOfPoints] = {0,10};
  unsigned short int ticks[numberOfPoints] = {30, 30};
  envelopeOne.initEnvelope(points, ticks, numberOfPoints, 1);

while(true)
  {
   Serial.printf("\r\n%d", envelopeOne.getEnvelope());
   delay(100);
  }
