oh well,
casting the line2 variable to float and changing teller++ to teller=teller+1 fixed it.

serial.list() limitations on mac?
Hi there. I'm running 2.0b6. When I do println(serial.list()); i get just ten values and I can't access the desired port. When I try doing
myPort = new Serial(this, "/dev/slave", 9600);
it seems the program doesn't work as expected - it just doesn't see the port (I can change it to any other non-existing value, and again, no-errors, just nothing).
Is there any ways to get to other ports listed in my /dev directory?

All MIDI Devices Unavailable?
Hi,
I hope I've picked the right location for this post.
I am a beginner with processing and with Java in general. I'm trying to figure out how to simply construct a midi note on message and send it to an internal midi port application, that can then route it to a software synthesizer.
I'm using javax.sound.midi for this, and processing 2.0b6.
This is some code I have written to check what devices exist:
However, every single one of those devices, if it is not in the try, catch block that discards MidiUnavailableException, will throw just that exception. Yet none of my devices should be in use for anything, so I'm not sure why all of them throw this error. Any thoughts?

That could be. I just wrote my own parsing characters into the code that I use .indexof to find and cut out the values I need. It is not elegant, but it works. Thanks for the help.

You need to call output.close() when you finish receiving data.

Scaling text
Hello, I am trying to create text that changes in size according to the frequency of the song being played. I have managed to get it to work, however one problem that I am facing is that the text does not scale in a center alignment (I want the size of the text to change but the position remain the same), but rather it scales outwards, is there any way I can work around this? Thank you so much for reading this and helping!
Here is my code:
import ddf.minim.*;
import ddf.minim.signals.*;
import ddf.minim.analysis.*;
import ddf.minim.effects.*;
Minim minim;
AudioPlayer song;
FFT fft;
PFont Header;
int leftcol = 50;
int row1 = 35;
float[] Channel = new float[10];
void setup(){
size(600,600);
Header = loadFont("font1.vlw");
minim = new Minim(this);
song = minim.loadFile("craveyou.mp3", 512);
song.play();
song.mute();
fft = new FFT(song.bufferSize(), song.sampleRate());
fft.logAverages(32,1);
}
void draw(){
calculateFFT();
background(0);
smooth(8);
textFont(Header, Channel[4]);
fill(255);
textAlign(CENTER,CENTER);
text("a", width/2, height/2);
}
void stop(){
song.close();
minim.stop();
super.stop();
}
void calculateFFT(){
fft.forward(song.mix);
Channel[0] = map(fft.getAvg(0), 0, 69, 0, 255);
Channel[1] = map(fft.getAvg(1), 0, 106, 0, 225);
Channel[2] = map(fft.getAvg(2), 0, 119, 0, 255);
Channel[3] = map(fft.getAvg(3), 0, 66, 0, 255);
Channel[4] = map(fft.getAvg(4), 0, 29, 0, 255);
Channel[5] = map(fft.getAvg(5), 0, 16, 0, 255);
Channel[6] = map(fft.getAvg(6), 0, 15, 0, 255);
Channel[7] = map(fft.getAvg(7), 0, 7, 0, 255);
Channel[8] = map(fft.getAvg(8), 0, 3, 0, 255);
Channel[9] = map(fft.getAvg(9), 0, 0, 0, 255);

Re : Scaling text
I'd thought that
- textAlign(CENTER,CENTER);
You can use textwidth and textheight (does it exist??) and say
- text("a", width/2 - textwidth ("a") / 2 , height/2 - textheight ("a") / 2 );
(not tested)
textwidth and textheight (does it exist??) should know the current size of your "a"
↧
Re : Scaling text
The alignment is working, but some fonts won't say how many pixels they increase in size correctly, so the alignment is not adjusting properly. You can get the textAscent, apply a calc on it, then use this as the start position for your Y. Also note this behaviour changes if you use P2D, P3D or OPENGL.
textAscent(). http://processing.org/reference/textAscent_.html
Here is my suggestion to start fixing this:
textAscent(). http://processing.org/reference/textAscent_.html
Here is my suggestion to start fixing this:
- void draw(){

- textFont(Header, Channel[4]);
- fill(255);
- textAlign(CENTER,CENTER);
- float yStartPos = calculateAscent(Channel[4]);
- text("H", (width/2), yStartPos);
- }
- float calculateAscent(float value) {
- float base = height / 2;
- float scalar = 0.1; // Different for each font, change this until you get the result you want
- float a = textAscent() * scalar; // Calc ascent
- stroke(100); // for the reference line
- line(0,base-a,width,base-a); // ref purposes
- return base-a;
- }

PVector functions and CPU vector processing? (SSE functions)
Hi there,
I discovered that the PVector class methods don't use the Processors vector registers and commands (SSE).
So I was wondering if there are any plans to use calculations with the vector unit of the processor in future builds,
as it might significantly improve speed.
Yet I have only experience in using vector units with plain c+asm, not yet in java, otherwise I'd look into it myself.
cheers :)
