RAMP

Arduino Interpolation Library

New objects

The library add a class template to manage interpolation beetween values of various data types.

  • ramp default ramp object for "byte" interpolation
  • rampByte ramp object for "byte" interpolation
  • rampUnsignedChar ramp object for "unsigned char" interpolation
  • rampChar ramp object for "char" interpolation
  • rampInt ramp object for "int" interpolation
  • rampUnsignedInt ramp object for "unsigned int" interpolation
  • rampLong ramp object for "long" interpolation
  • rampUnsignedLong ramp object for "unsigned long" interpolation
  • rampFloat ramp object for "float" interpolation
  • rampDouble ramp object for "doubl" interpolation

Methods

  • go() go to a new value

  • pause() pause the interpolation

  • resume() resume from pause

  • update() update value of the interpolation according to its parameters

  • getValue() get actual value of the interpolation

  • getOrigin() get last origin value of the interpolation

  • getTarget() get last target value of the interpolation

  • getCompletion() get the completion percentage of the interpolation

  • getDuration() get last duration of the interpolation

  • setGrain() set interpolation grain

  • setAutomation() set automation mode

  • isPaused() pause state

  • isRunning() running state

  • isFinished() finish state

Examples

First you need to instanciate the object as a global variable :

ramp myRamp;

Then you need to a new value to reach :

myRamp.go(new_value, (ramp_duration), (ramp_mode), (loop_mode));

At least you'll need to update to get the actual interpolation value :

myInterpolationValue = myRamp.update();
