Arduino SyncWaveforms implements timed functions that runs synchronously, so it doesn't depends of the time elapsed between calls. Usefull, for example, for lightning effect or motor/robots controlling.
For example, imagine a LED that blinks slowly using a Sin wave, but also makes a 'highlight effect' when you push a button (or somethink like that). With SyncWaveforms is very easy to achieve this kind of behaviors.
The base brick of Arduino SyncWaveforms are SyncFunctions (Delta, Zeros, Constant, Step, Ramp, InverseRamp, Triangular, Trapezium, Sin and Cosine) All basic functions have a Interval (t), and returns a Y range between 0.0 and 1.0.
auto delta = SyncDelta(250);
auto zeros = SyncZeros(250);
auto constant = SyncConstant(250, 1.0);
auto step = SyncStep(250);
auto ramp = SyncRamp(250);
auto iramp = SyncInverseRamp(250);
auto sim_tri = SyncTriangular(250);
auto asym_tri = SyncTriangular(100, 150);
auto sim_trap = SyncTrapezium(250);
auto asim_trap = SyncTrapezium(50, 150, 100);
auto sine = SyncSin(250);
auto cosine = SyncCos(250);Then, you can modify this functions chaining SyncTransformations (Speed, ScaleY, OffsetY, SliceX, Delay, Inverse, Reverse, Repeat or mirroring)
sine.ScaleY(3.0).OffsetY(1.0).Speed(0.5).Repeat(5);You can concantenate several SyncFunction with operator '+'
auto compound = (ramp + constant + zeros).Repeat(3).ScaleY(3.0);Finally, you also can 'Restart()' any SyncFunction.
#include "SyncWaveforms.h"
auto pwm = SyncStep(1000).Repeat();
void setup()
{
while (!Serial) { ; }
Serial.begin(115200);
}
void loop()
{
Serial.println(pwm.GetValue());
}
void setup()
{
while (!Serial) { ; }
Serial.begin(115200);
auto ramp = SyncRamp(150);
auto constant = SyncConstant(300, 1.0);
auto zeros = SyncZeros(200);
auto compound = (ramp + constant + zeros).Repeat(3).ScaleY(3.0);
}
void loop()
{
Serial.println(compound.GetValue());
}
#include "SyncWaveforms.h"
void setup()
{
while (!Serial) { ; }
Serial.begin(115200);
auto sin = SyncSin(1000).Repeat();
auto trigger = SyncTrapezium(150, 150, 150);
auto newMillis = millis();
auto lastMillis = newMillis;
const auto endMillis = newMillis + 10000;
while(newMillis < endMillis)
{
newMillis = millis();
Serial.println(max(sin.GetValue() * 0.5, trigger.GetValue()));
// just some timig to simulate and event
if(newMillis - lastMillis > 3000)
{
lastMillis = newMillis;
trigger.Restart();
}
}
}
