using processing on android phone to control an old pen-plotter

in Android Processing • 3 years ago

I've started a little project that implies controlling old pen-plotters with Android mobiles.
The client is written using Processing for android with oscP5 library,
on server-side I use python and chiplotle HPGL library.
data is exchanged through osc messages.

this is a first proof-of-concept
the video is really blurry, sorry, but I had no tripod and only two hands

sooooo good.and I had tried oscP5 before,but it didn't work.would you mind share any process to show that how oscP5 work with processing for android if is possible.thanks.

this is my first test-client.
It's not optimized at all and really naif, sorry
(i get lot of too many sockets errors, but it basically works)
if you have tips to improve it, it would be really useful

int port = 12345;
// inserire sempre il numero ip corrente
String ip = "127.0.0.1";
int x;
int y;
NetAddress myRemoteLocation;
void setup() {
size(800,480);
background(255);
frameRate(25);
setRequestedOrientation(android.content.pm.ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
/* set up a remote location */
myRemoteLocation = new NetAddress(ip,port);
}
void draw() {
}
void mousePressed() {
// create a new OscMessage with an address pattern, in this case /mouse_down.
OscMessage myOscMessage = new OscMessage("/mousedown");
// add a value (an integer) to the OscMessage
myOscMessage.add(mouseX);
myOscMessage.add(mouseY);
//send the OscMessage to the remote location.
OscP5.flush(myOscMessage,myRemoteLocation);
x = mouseX;
y = mouseY;
}
void mouseDragged() {
// create a new OscMessage with an address pattern, in this case /mouse_down.
OscMessage myOscMessage = new OscMessage("/drag");
// add a value (an integer) to the OscMessage
myOscMessage.add(mouseX);
myOscMessage.add(mouseY);
//send the OscMessage to the remote location.
OscP5.flush(myOscMessage,myRemoteLocation);
// draws on screen
stroke(0);
line(x,y,mouseX,mouseY);
x = mouseX;
y = mouseY;
noStroke();
}
void mouseReleased() {
// create a new OscMessage with an address pattern, in this case /mouse_down.
OscMessage myOscMessage = new OscMessage("/mouseup");
// add a value (an integer) to the OscMessage
myOscMessage.add(mouseX);
myOscMessage.add(mouseY);
//send the OscMessage to the remote location.
OscP5.flush(myOscMessage,myRemoteLocation);
}
void keyPressed() {
if(key == CODED) {
if (keyCode == MENU) {
OscMessage myOscMessage = new OscMessage("/margins");
//myOscMessage.add(width);
//myOscMessage.add(height);
// IMPORTANTE: per android cambiare con le seguenti righe
myOscMessage.add(screenWidth);
myOscMessage.add(screenHeight);
OscP5.flush(myOscMessage,myRemoteLocation);
background(255);
}
}
}

Re: using processing on android phone to control an old pen-plotter

I'm writing a multi-client server, allowing for concurrent remote art events with pen plotters :)
I have a first working example, where each registered client is given a portion of a larger sheet on the plotter.
server receives osc messages and takes care of plotting at the right position in the sheet
this is just an example output with nine clients sharing simultaneously the same plotter.

hi,thanks for sharing!

Just tried Multicast way to let MulticastA and MulticastB communicate with each other. in computer, they works very well.

But when build MulticastA to Processing for Android emulator, and leave MulticastB in computer, they did not work.(already set up the network permissions)

i really have no idea to let them work,,,,any feedback will be really helpful. thanks so much!

MulticastA

// Requirements
// * oscP5 (http://www.sojamo.de/libraries/oscP5/)
import oscP5.*;
import netP5.*;
OscP5 oscP5;
void setup() {
size(400,400);
oscP5 = new OscP5(this, "239.0.0.1", 7777);
}
void draw() {
background(0);
}
void mousePressed() {
OscMessage myOscMessage = new OscMessage("/test/0/state");
myOscMessage.add(1);
oscP5.send(myOscMessage);
}
void mouseReleased() {
OscMessage myOscMessage = new OscMessage("/test/0/state");
myOscMessage.add(0);
oscP5.send(myOscMessage);
}

MulticastB

// Requirements
// * oscP5 (http://www.sojamo.de/libraries/oscP5/)
import oscP5.*;
import netP5.*;
OscP5 oscP5;
void setup() {
size(400,400);
oscP5 = new OscP5(this, "239.0.0.1", 7777);
}
void draw() {
//
}
void oscEvent(OscMessage theOscMessage) {
// /test/*/stateにマッチ
if (theOscMessage.addrPattern().matches("/test/\\*/state")) {
println("id: *");
}
// /test/0/stateや/test/1/stateなど任意の数字を持つパターンにマッチ
if (theOscMessage.addrPattern().matches("/test/[0-9]*/state")) {
// /test/0/stateを/でsplitした場合の結果は以下のようになる
// [0] ""
// [1] "test"
// [2] "0"
// [3] "state"
int id = Integer.parseInt(theOscMessage.addrPattern().split("/")[2]);
if (theOscMessage.checkTypetag("i")) {
int value = theOscMessage.get(0).intValue();
println("id: " + id + ", value: " + value);
if (value == 1) {
background(255);
}
else if (value == 0) {
background(0);
}
}
}
}
