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 "double" 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 / milliseconds
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_in_ms), (ramp_mode), (loop_mode));

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

myInterpolationValue = myRamp.update();

Unless mentionned all time/duration values are in ms.
