I would like to know if there are any API's for python to programmatically control a phone, like starting and ending calls, but also to record conversations.
I would also like to use the Headphones and Mic of the computer to talk over the phone.
Any info would be great, I tried googling for something, but nothing useful came up.
Be careful when using PyBluez! The results will actually depend on the BT-USB dongle you are using. Depending on the hardware(the BT chip in there), PyBluez will use one or another BT stack - for example there was one from WIDCOMM. Results will vary, as PyBluez is actually wrapping around those stacks - all of which are far from complete.
So, when you have a working project, be sure to know what actual BT stack you were using :)
For Python audio stuff, you could try this.
PyBluez is an effort to create python wrappers around system Bluetooth resources to allow Python developers to easily and quickly create Bluetooth applications.
Unfortunately I've not found a page dedicated to its features, but it could be a good starting point, whether everything you need is in its feature set, or if you could build your application upon it by extending it.

I've got a Brother ADS-1000W receipt scanner and using the ControlCenter4 software it works great. However I would like to be able automate the scanning process and I can't find any pointers/clues on where to get access to the ADS-1000W specific features. With the ControlCenter4 software, I can have the scanner deskew images. It also scans to an arbitrary length and width (matching the scanned receipt). I'm assuming this is being handled by the scanner, but it may be happening in the ControlCenter4 software. These features specifically don't seem to be accessible in the TWAIN interface. I tried using TWAINCommander 3 and it doesn't show the deskew and arbitrary size features in the TWAIN interface.
I've got both Linux and Windows machines available and I'm cool with a commandline solution or an SDK that I have to write software to implement. If it's an SDK, I prefer Python.
I know this is somewhat open-ended, but hoping someone can point in a direction for further research.
Just in case anyone else stumbles across this question: The ADS-1000W supports scanning to FTP. If PDF is selected, then the scanner supports the de-skew option, so I installed vsftpd on my linux box and used Python to process the files as their uploaded.
I'm excited. I'm a long-time lurker here at SO, but I've never posted. Here goes!
I'm trying to develop a device that would connect to a host RPi through (preferably) USB, and would have multiple 3.5mm jack outputs. The goal, ultimately, is to get the device to use a standalone program that, when a button is pressed (keyboard, or other external input), a specific sound (or set of sounds) would go through a single 3.5mm output. Now, I understand that there's going to (most likely) have to be an external box, and I also realize that I'm in above my head, but I'm trying to create this as more of a hobby and as a learning experience.
Basically, the way it would go is that the user would set which inputs triggered which outputs beforehand on the custom software in the RPi. The input would then trigger that ouput then await a new signal. I figure I'm going to need to also build a physical box to house the amount of 3.5mm jacks I want (i figured 3-5.)
So, where do I need to start? I don't need a guide on how to do this, more of a step in the right direction. From what I can discern, there's not anything out there that does this. If there is, please show me and I'll get that instead. I've done a lot of googling on this, and I'm thinking that I'll use Raspbian on the Rpi, and code the software using Python. I know I'll also need to build a driver so that the external box and the RPi can communicate. Lastly, I assume that I'll need some type of circuitry for the external box. That's where it gets hairy to me. I've never dealt in physical I/O except for a bit of modding. Where would I start my search there?
Any help at all is appreciated, and thanks for reading this huge post. Thanks!!!!!!!!!!!!
I have a robotics type project with an Arduino Uno, and to make a long story short, I am experimenting with some AI algorithms. However, I need to implement some high level matrix algorithms that would be quite simple using NumPy/SciPy, but they are an utter nightmare in C or C++. Even with the libraries out there, this is just getting ridiculous.
Is there any way I can do this project in Python? I think I heard something about the Mega having this capability, but I have an Uno, and replacing it is not an option at this point (that would set the project back quite a bit.) Also, I heard somethings about using Python to communicate to the Arduino via USB, but I cannot have the USB cable in while the thing is running. I need to be able to upload the program and be done with it.
Are there any options out there, or have I just reached a dead end?
There was a talk about using Python with robotics at this years PyConAU called Ah! I see you have the machine that goes 'BING'! by Dr. Graeme Cross.
The only option he recommended for using Python on a microcontroller board was PyMite which I think also goes by the name of Python-On-A-Chip.
It has been ported to a range of boards - specifically he mentions the Arduino Mega which you said is not an option for you, but it is possible it is supported on other Arduino boards.
However, because it is a "batteries not included" version of Python it is more than likely that you will have a real problem getting numpy/scipy etc up and running.
As other posters have suggested, implementing in C might be the path of least resistence.
Update: again, not specifically for Arduino, but pyMCU looks to provide python on a chip. The author states he may look at developing an Arduino version of pyMCU if there is enough interest.
I've started work on a "Little Python" to C++ (called Pyxie - a play on Py CC- Pyc-C) compiler, with the specific aim of compiling a sane subset of python to C++ such that it can run on an arduino.
This is far from complete at time of writing (0.0.16), but it can currently compile a very small subset of python - enough for the arduino "blink" example to run. To support this, it has a compilation profile - which essentially means "compile using the arduino toolchain."
A program it can compile looks like this:
led = 13
pinMode(led, OUTPUT)
while True:
digitalWrite(led, HIGH)
delay(1000)
digitalWrite(led, LOW)
delay(1000)
This parses, performs analysis (like type inference, etc), compiles to C++, which is then compiled to a hex file, which you can load onto your device.
There's a long way to go before it's useful, but it is progressing and does have a roadmap/etc.
PyPI - http://pypi.python.org/pypi/pyxie
Homepage - http://www.sparkslabs.com/pyxie/index.html
In particular a key difference from Micropython (and PyMite) is that it's designed to compile to devices too small to run either implementation. (This also means it's very different from things like ShedSkin which while a Python to C++ compiler target larger execution environments)
It's going to be difficult to get any kind of Python script running directly on the Arduino uno.Reason is that it is an interpreted language, so you will need a interpreter on-board in addition to the plain text script. There is probably not going to be enough memory for all of thatin arduino uno.
What you can do best is to find a way to compile a Python script to native machine code (this is how C/C++ works). I have seen projects around to do something like that for other platforms, but (as far as I know) none which does it successfully for Arduino uno yet.

wish this will help you.
thanks!
This is not a direct solution but in your circumstances If I were you, I would write the AI program on my computer and the rest of it in Arduino. after that I would write a flask server with my AI program. and then, port forward from my router to the local machine. finally, make requests from Arduino to the server.
I have a working GPIB interface and Linux-GPIB package installed and working.
I only know two commands at the moment, x.write and x.find. I don't know much about Python, but I recognize the dot operator and realize that after importing gpib, I should get some functions at my disposal.
I have not been able to locate the list of GPIB functions.
They are in the gpib library. You reference them like so: gpib.foo().
Add this line into your code:
help(gpib)
And browse through the functions/classes.
If you are working in Python, I think the pyvisa is what you are looking for. It provides lots of useful high level functions which helps you to send a series of SCPI commands to your equipment via GPIB, such as write, read,ask and so on.
As for SCPI commands themselves, usually they will differ from the different vendors. So in terms of what kind of SCPI you should send to the equipment, you should read the corresponding datasheet. But in the other case, you could have installed the drivers which were provided by the vendor. In this case you can send some even higher commands. For instance, if you would like to control a voltage source, they have probably already got the function setvoltage(double voltage). Things will be much more easier for you.
Actually there are many commands available. Except those two you mentioned, there are x.read, x.ask, x.ask_for_value and so on.
But I recommend your to read those help file, I think that will give you a better understanding.
I have both Fruityloops and Propellerheads Reason software synths on my Windows PC.
Any way I can get at and script these from either Visual Basic or Python? Or at least send Midi messages to the synths from code?
Update : attempts to use something like a "midi-mapper" (thanks for link MusiGenesis) don't seem to work. I don't think Reason or FL Studio act like standard GM Midi synths.
Update 2 : If you're interested in this question, check out this too.
Both applications support MIDI. It's just that they don't see each other.
In order to send messages via MIDI between applications, you need to install a virtual midi port.
There are several freely available, but this one works: http://www.midiox.com/zip/MidiYokeSetup.msi
You'll get a virtual MIDI output port that you can write to as if it's a normal MIDI device. In Fruity Loops or Rebirth you choose that port as the input. That's all you need to do to connect the programs.
It'll work like this:
Your Application --> Virtual MIDI Port --> FruityLoops
Note: This answer doesn't exactly answer the question you asked but it might achieve the result you want :)
You can author a VST plugin in Java using jVSTWrapper (http://jvstwrapper.sourceforge.net/). If you really wanted to use Python you could use Jython to interface to java and do it that way. Alternatively you could just write the plugin in Java or another scripting language for the JVM like Groovy.
I think both FL Studio and Reason can be configured as the default MIDI playback device. To send MIDI messages to either from VB.NET, you'll need to PInvoke the midiOutOpen, midiOutShortMsg and midiOutClose API calls. Here's a link to code samples:
http://www.answers.com/topic/midioutopen
They're for VB6, but they should be easy to translate to VB.NET.
I know FL Studio can be "driven" from a plugin authored for FL (or a VSTx plugin), but I think these are always written in C or C++.
Edit: I just learned that Windows Vista dropped the MIDI Mapper (which would have made setting up FL or Reason as the default MIDI device simple). Amazing. Here is a link I found with an alternative solution:
http://akkordwechsel.de/15-windows-vista-und-der-midi-mapper/
I just tried it out (it's just a *.CPL file that you double-click to run) and it appears to work (although the GM Synth is the only option available on my laptop, so I'm not sure if it will pick up FL or Reason as choices).
What you need is a VST MIDI scripter / scripting plugin to create a logic of MIDI events that can be sent to any MIDI channel. You would need to set a MIDI channel in FL for the VST instrument/effect you need to tweak its values. Google for it there are some plugins around and please share them back here if you find anything useful :)
You could write a Rewire host. Though, you will have to get a license (the license is free, but your application must be proprietary, so no open source).
Alternatively, you could interface through MIDI messages.
Finally, you could implement a dummy audio device which would route the audio to/from wherever you want or process it in some way.
I imagine all of these would be reasonably difficult. MIDI is probably the easiest of the three (I have no idea how easy or hard the Rewire protocol is to use).
When it comes to Reason, you can do with it to much because of it's closed architecture - you can use VST plugins (or any other type like DirectX ones) - your only option is to use MIDI.
Regarding Fruity Loops, you could write a VST plugin that can take an input from a scripting language (VB, Python or whatever) but in order to write such thing you would have to use Delphi or C++.
Alternatively, you can check out MAX made by Cycling74 - it's something like a IDE for music ;-) - and I'm pretty sure you can use Python with it.
There's an opensource music workstation, called Frinika, and you can script that in Javascript. (Insert / delete notes , change midi effects like pitch wheel etc.) It can import / export regular midi files, so it will work with Fruity loops or whatever else you have.
// Insert New
song.newLane("MyMidiLane", type("Midi"));
lane = song.getLane("MyMidiLane");
part = lane.newPart( time("10.0:000"), time("4.0:000") );
part.insertNote(note("c#3"), time("11.2:000"), time("2:0"), 120 );
part.insertNote(note("f3"), time("11.3:000"), time("1:0"), 100 );
part.insertNote(note("g#3"), time("11.3:000"), time("1:0"), 100 );
part.insertNote(note("b3"), time("11.3:000"), time("0:64"), 100 );
part.removeNote(note("f3"), time("11.3:000"));
part = song.newLane("MyTextLane",
type("Text")).newPart(time("24.0:000"), time("10.0:000"));
part.text = "This is the test text to be inserted.";
part.lane.parts[0].remove(); // remove initially inserted text-part
Another example for reading/changing notes:
lane = song.getLane("MyMidiLane");
// a lane has a fixed instrument assigned
lane.parts[0].notes[0].duration=64
lane.parts[0].notes[1].duration=32
lane.parts[0].notes[1].startTick=120
// Parts are blocks of notes that you can drag around together in the Frinika GUI.
// They're like patterns in trackers.
for (i in lane.parts[0].notes){
println("i: "+i+", n: "+noteName(lane.parts[0].notes[i].note));
println("i: "+i+", dur: "+lane.parts[0].notes[i].duration);
println("i: "+i+", startT: "+lane.parts[0].notes[i].startTick);
}

It has a Java Webstart launcher as well, so you don't even have to
install.
It used to bundle the Javadoc documentation as well, but for some
reason their latest downloads don't include that. It's a pity, because
that's where the Javascript bindings are documented. So, now you have
to browse the source or build the Javadoc yourself. (It has some built-in examples that are accessible from the scripting window, you should check them out first. My first example is from there.)
Here is the sourcefile where you'll find the Javascript docs:
frinika Javascript doc/source
But there are other options as well. You can check out mingus too, which is a Python library for music theory and midi file handling. It requires Fluidsynth, and the demo apps require GamePython too, so it's a bit more complicated to setup than Frinika.
P.S.:
Frinika has a particular bug: when dragging around neighbouring notes, some might not sound the right length. You can help that by transposing forth and back the consecutive notes (fairly fast in piano roll view), or dragging the part that contains the notes forth and back. Restarting Frinika will also help, but that's the slower way. So this bug won't affect saved files, neither midi export.
