PulseIn() in Processing

Hello friends!

Is there an equivalent Arduino command PulseIn( ) in Processing? I want to count ms between HIGH and LOW.

Thanks,

João Alexandre

Perlin noise plot graphic

Hi!!

I wrote this little code to plot a updated graphic of a Perlin noise in a 720x240 window , this is done

by shiftting the plot to left side of the window each second; but the plot is updated only when I minimize

and again maximize the window. Where is my mistake? Can someone help me?

Thanks, planctum.

//Plot Perlin Noise

//by planctum, nov30.2010,version:1.0

int i=0;

int j=0;

int k=0;

int n=1000;

int prevMillis=0;

int tamMatrx=3000;

int amplitude=300;

float p=0.0;

float[] m=new float[tamMatrx];

//

void setup(){

size(720,240);

for(j=0; j<tamMatrx; j++){

m[j]=noise(p);

p+=0.01;

strokeWeight(1.5);

smooth();

}

}

//

void draw(){

for (k=0; k<= tamMatrx; k++){

j=k;

background(255);

for(i=0; i<=width; i++){

point(i, amplitude*m[j]);

j++;

}

prevMillis=millis();

while(millis() - prevMillis <= n){ }

}

}
