Python makes it extremely easy to write fairly complex programs quickly. It has clean, easy to read, syntax, a very complete standard library (files, sockets, regular expressions, win32 functions, etc.) and efficient.
It's ideal as a glue to deal with the main logic of a program, while time-critial subroutines are written in C. Extending Python in this way is very easily done. Python programs are portable to just about every available platform without changing the source. It's also easy to build sophisticated (and portable) GUI's very quickly using the standard TkInter package.
Some guides on picking up Python:
See http://www.python.org/moin/BeginnersGuide for the beginners guide.
Various introductions to python at http://www.python.org/doc/Intros.html
See the quick reference to get started quickly at http://rgruet.free.fr/PQR2.2.html
It's very easy to build GUI's with Python using TkInter (which comes with Python). See BuildingTkInterfaces for more details.
It's very easy to extend Python with C/C++ (in fact, that's what Python's often used for -- gluing together bits of C code). There are full details for doing this on the iPaq at ExtendingPython.
You need to copy the files inside the tkinter.zip directory tcl8.3 into \program files\python (they should be library and tk8.4). Copy the windows directory over the \windows directory on the device.
NB You need to include the following line at the top of iPaq tkinter programs to get them to work:
import sys sys.path.append('\\Program Files\\Python\\Lib\\python23.zip\\lib-tk')
Setting up the registry
Open setup-registry.lnk from the file explorer -- now double clicking .py files should open them.
Python interpreter server
If you put server.py in \program files\python\lib and then run it, you can telnet in on port 8653 and use the interactive intepreter remotely. If you're using putty (recommended), set "Implict CR with each LF" in the "Terminal" page.
SDL and PyGame
Dynamics and Interaction Extensions
A number of special extensions are being implemented for use within the group. These include XSens access, vibrator control, MESH access, sound and speech synthesis, GapiDraw, OpenGL, matrix libraries, Gaussian Process code and simple neural networking code. See DiPythonExtensions for current status.
