What steps will reproduce the problem?
1. Arduino Pro Mini 3.3v 8MHz with FTDI drivers on any computer (tried on 
3 desktops and two laptops)
2. Use software from here
3. Connect and disconnect a probe wire (tried with 5amp, 8amp and 13amp 
(240v) solid copper wire)

What is the expected output? What do you see instead?
Low voltage readout (when not probing hopefully 0v), with activity only 
when placed upon a signal generating component or part. ~0.3v trace with 
0.8 max (as shown in picture) when only the arduino is connected but when 
a probe wire is connected the max goes straight to 4.8v and the trace 
becomes more irratic. Nothing else is done to the system at all. I have 
even tried connecting 4 probe wires and trying to remove the noise by 
touching other pins on the board.

What version of the product are you using? On what operating system?
Up to date. XP, XP x64, 7, Linux, OSX

Please provide any additional information below.
JPEG supplied has 12 trace graphs (6&6). ProMini is attached to FTDI 
cable, probe cable is attached to ProMini (in this case A0 but same occurs 
at all pins), FTDI cable is then plugged into computer and Processing in 
run. Digital traces have no traces, hopefully because nothing was attached 
and connected.

What steps will reproduce the problem?
1. Downloaded latest Processing 
2. Uploaded the required code to my Arduino UNO 
3. Ran the unmodified Processing code
4. Connected only one input - A0

What is the expected output? What do you see instead?

There was output, but all the windows are showing the output of that one lead.

What version of the product are you using? On what operating system?

Debian wheezy/32 bit, kernel 2.6.38.

Please provide any additional information below.

When I start up the Processing script, this appears in the runtime log:

Please provide any additional information below.

What steps will reproduce the problem?
1. Upload arduinoscope to Arduino Duemilanove
2. Run the windows APP
3. All channels show same value no matter which channel is physically connected 
to the test point

What is the expected output? What do you see instead?
I was expecting all 5 channels to show different values when connected to diff 
test points on my circuit but all channels show same value.

What version of the product are you using? On what operating system?
Windows 7, arduino 1.01, processing 1.5.1

Please provide any additional information below.
I was testing the arduino scope. So I connected channel 0 to the 3.3v supply 
provided on the arduino board, and I see all channels output changed to 3.3 v 
on the PC software. if I move the connection to pin 1 or 2 or 3 or 4 or 5, all 
channels show the same value. is this how the scope should be behaving?

I also monitored the values on a serial terminal and all 6 channels show same 
values or at least very close values, even when only one of them is connected.

Am I missing something?

Thanks,
Sam

What version of the product are you using? On what operating system?

I've tried processing versions 1.0.1 and 1.0.6 on Vista32 (java build

Please provide any additional information below.

it seems Processing isn't recognizing arduinoscope as a library. dropping 
P5 and openCV into the Sketchbook/libraries folder works as expected, but 
processing seems to be ignoring arduinoscope...

I've also tried moving the arduinoscope.java file into various locations, 
including the libraries folder of the processing application directory.

What steps will reproduce the problem?
First run... I got by the processing code this:

'The function readStringUntil(int) does not exist'

What is the expected output? What do you see instead?
Nothing

maybe I have no idea what I'm doing but the zip file for the standalone
application for OSX looks like a bunch of uncompiled code?  How do I make
it work?

Hi,

Is it possible to change the step-size in x direction? I working on a photon 
counting project for a secondary school, and my Arduino counts every 250 ms 
(the counts are mapped to 0-1023 in the Arduino) Now I get a stair-case 
pattern. I like to have a smaller step in x-direction (e.g. 5 pixels).

I hope I did not miss an simular issue.

What steps will reproduce the problem?
1. Run the SimpleSerialArduinoscope example on a slow PC (I am using an
Intel Atom N270 on Windows XP).
2. The CPU usage of java.exe will remain constant at 95%.
3. Soon after it will crash:

Exception in thread "Animation Thread"
java.lang.ArrayIndexOutOfBoundsException: 4
    at SimpleSerialArduinoscope.draw(SimpleSerialArduinoscope.java:124)
    at processing.core.PApplet.handleDraw(PApplet.java:1425)
    at processing.core.PApplet.run(PApplet.java:1327)
    at java.lang.Thread.run(Thread.java:619)


What is the expected output? What do you see instead?
No Crash.

What version of the product are you using? On what operating system?
Aug 26 release zip, built from source. Windows XP.

Please provide any additional information below.
I guess some serial data is being dropped due to the high CPU load. I have
done a little investigation and the crash happens here:

  for (int i=0;i<scopes.length;i++){
    // update and draw scopes

    scopes[i].addData(vals[i]);  <--- vals[i] is out of bounds.

I have worked around the problem by modifying:

void serialEvent(Serial p)

so that it dropps short packets. i.e.

void serialEvent(Serial p) { 

  String data = p.readStringUntil(LINE_FEED);
  if (data != null) {
    int[] tempVals = int(split(data, ' '));
    if(tempVals.length>=scopes.length) {
      vals = tempVals;
      }
    else {
      println("Warning: Dropped a short packet.");
      }
  }
}

But I wouldn't expect an application like this to be quite so CPU intensive!

After getting something like 5 samples per second, and Java hogging 1005 of my 
CPU, I decided to create a different solution, it's called lxardoscope, 
available from http://lxardoscope.sourceforge.net/ .
Features:
    - display modes: two channels, time/add/xy
    - vertical: 2mV to 10V per division
    - overall gain control for calibration
    - horizontal: 100us to 5 sec, for full sweep
    - trace position adjustments: vertical and horizontal
    - trigger: on/off, channel 1 or channel2, rising or falling edge
    - trigger level: -10 to +10V
    - signal level measurements: max, min, pp, avg, rms
    - signal levels and time shown for mouse pointer location selected on display 
    - up to 3000 samples per second, per channel
    - option for recording input data stream to file
    - option to display recorded data from file
    - timebase calibration adapts to Arduino's conversion speed
    - GND calibration allows for selecting arbitrary GND potential

What version of the product are you using? On what operating system?
Arduino 0017 On Windows XP SP3

Both the binaries and source from the supplied zip and Linux tar.gz file 
(and I'm assuming the Mac one as well) have a bug in the serialEvent() 
function whereby the vars variable that is updated is a local one rather 
than the global one used  by draw().

I notice this has been corrected in the SVN source, with which I've had no 
problems. Could packages containing updated binaries be supplied so that 
others weren't as confused as I was?

Thanks :).

What steps will reproduce the problem?
1. Connect Arduino UNO and upload sketch
2. Launch processing and the SimpleSerialArduinoscope
3. Nothing happens

What is the expected output? What do you see instead?
I expect to see the same output like my Duemilanove 328p, but with the UNO all 
channels show readings of 0

What version of the product are you using? On what operating system?
Latest Arduino IDE and Processing, Mac OS x 10.6.7

I needed triggers and faster updates so I wrote a Mac app that is similar.

main differences:
 - single channel
 - up to 360,000 samples/sec
 - triggers
    + internal rising/falling and auto
    + external via digital #12

I'm adjusting the ADC clock setting to get faster sampling and running the
serial port at 2Mbaud to handle the datarates.
