Hi,

Been playing with gicentre library http://gicentre.org/utils/ specifically "Embedding Sketches in a Single Window" as SketchPanels, same as example on site. Got it running fine but can't set sizes of the assorted sketches. 

Eg something like following, assuming different size is called in each of the subclasses. Only seems to divide the screen equally in two based on the initial size(800, 480) calling function, doesn't do what you tell it from the subclasses. Is there a way of doing it. IE I have one side as 640*480 and the other as 160 * 480, stick video stuff in one and controls in another. All works but sizing of the panels doesn't.

Using PopupWindow() different sizes happen okay although still to figure how to place them on the screen so you can see them all.

Is it possible to force an X size instead of default of half?

Thanks

Stefan

void setup()
{
size(800,480);
setLayout(new GridLayout(0, 2));
noLoop();

PFont font = createFont("Serif",32);
textFont(font, 32);
smooth();
textAlign(CENTER,CENTER);
fill(120,20,20);
rotationAngle = 0;

ASketch sketch1 = new ASketch();
AnotherSketch sketch2 = new AnotherSketch();

  SketchPanel sp1 = new SketchPanel(this, sketch1);
add(sp1);
sketch1.setIsActive(true);

  SketchPanel sp2 = new SketchPanel(this, sketch2);
add(sp2);
sketch2.setIsActive(true);
}

Hi all,

Busy writing code to control a GPIB bus over a serial port and for the most part works reasonably.

While I have all the Serial port stuff happening one feature that I really need is to know when the UART TX Buffer is empty. IE so can know a full string was sent out the port before making an attempt to write the next string. Responses from devices on the GPIB bus have varying latency and in some cases don't like commands being sent one after the other in quick succession. I could just use timed events but gets messy and really not that efficient.

Having a means to know when the Transmission was complete would be useful.  Ploughing around I found reference to this, can be found in a few places related to Java but not on Processing site.

public void serialEvent(SerialPortEvent event)
{
switch (event.getEventType())
{
case SerialPortEvent.BI:
case SerialPortEvent.OE:
case SerialPortEvent.FE:
case SerialPortEvent.PE:
case SerialPortEvent.CD:
case SerialPortEvent.CTS:
case SerialPortEvent.DSR:
case SerialPortEvent.RI:
case SerialPortEvent.OUTPUT_BUFFER_EMPTY:
break;
case SerialPortEvent.DATA_AVAILABLE:
// we get here if data has been received
byte[] readBuffer = new byte[20];
try
{
// read data
while (inputStream.available() > 0)
{
int numBytes = inputStream.read(readBuffer);
}
// print data
String result = new String(readBuffer);
System.out.println("Read: "+result);
} catch (IOException e) {}

break;
}

Seems to have lots of juicy features but seems to be only usable from JAVA directly. Guess I don't understand how to use this but thats why I like processing, I don't have to fully understand and still get a lot of return for the effort.

Reading assorted peoples questions on the forum seems the sorts of things people ask for is here, but not accessible from the Serial library in processing. Especially things like knowing a framing error happened when an Arduino is slightly off frequency or even implementing hardware handshaking.

Has anyone included the above sort of serial events within processing and got it working? 

Thanks

Hi,

 

I'm using the G4P library. Want to open a spearate window and put a number of Serial Port options on screen, once the selections are made, be able to close that sub window. Done it for the main window and it works like a treat, but really not ideal.

 

 

How do I close a GWindow?

 

There is a good demo for opening G4P Windows but nothing for closing them. http://www.lagers.org.uk/g4p/applets/g4p_windowsstarter/index.html The normal window Exit also seems to be disabled. Can only close the extra windows by closing the main window.

 

Ideally being able to launch the sub window from a menu option would be nice. Am I right in say there is nothing done in the libraries for creating menu's?

 

The sort of menu typical of a standard PC application. I've played with JFrame JAVA way but that seems to remove me from Processing a bit too much. If I understood more it probably wouldnt matter, but I'm pleased with the fact that I'm starting to get my head around Classes and what they can do. Complicating that with direct JAVA stuff throws me at this stage.

 

Thanks

Stefan

 

 

 

 

 

 

Hi,

 

Been trying to figure out why my teext formatting isnt predicatable. Help.

 

I fill the strarray with data from a serial port. That seems to happen but this is the way it gets formatted on the console area.

 

Receiving :-
#00 0

#00 0,
#00 0,
#00 0,
#00 0

What I want is

 

Receiving :- #00 0

#00 0, #00 0, #00 0, #00 0

 

Second using the text command I want to print "A Test" to the screen. But it flickers briefly on the screen then dissappears.

 

void serialEvent(Serial myPort)
{
String input = myPort.readStringUntil(0x0D);

if((input != null))
  {
    println("Receiving :-" + input);
    strarray[pointer] = input;
    pointer++;
    if (pointer == 4)
      {
        pointer = 0;
      }
      myPort.clear();
  }
else
  {
   String joined = join(strarray, ", ");
   println(trim(joined));
  }
   text("A Test", 20, 200, 150, 30); 
}

 

Any clues?

 

Thanks

Stefan
