pyastra-general Mailing List for Pyastra

Dear PyAstra Support Community,

As part of my research at the MIT Media Lab, I am looking into ways of
running Python on a micro-controller.
Hence I came across PyAstra.

My question relates to the compatibility between PyAstra and Python.
Which version of Python does PyAstra support (2.7 or 3) ?

Thank you in advance
Kind Regards

Christophe Meyers

Hello.-

Where can i find a manual about pyastra?

Thanks

Today, 5th of April is Pyastra's birthday. 
 
Pyastra has been released four times this year. It became more stable 
and got more features every release. 
In the second year, we are going to make PyAstra's architecture more 
flexible. It will let us extend Pyastra much faster. 
 
Great thanks to our acitve users and to all people who helped us develop 
PyAstra!!!

New Pyastra preview release 0.0.4 is out!

Pyastra is now able to run assembler automatically. Now it supports ICD,
sleep mode, interrupts, multiple pages of program memory. The package
includes more examples. All known bugs were fixed.

Merry Christmas!

New Pyastra preview release 0.0.3 is out!

New pyastra is more stable, supports all PIC12, PIC14 and PIC16, 
includes examples and a little of documentation. Generated code 
efficiency is 30-40% more and it uses approximately 50% of RAM used 
before!!!

We have tested it in real work and it worked good, but anyway it may 
have some bugs, so it's still a preview release.

Dear Open Source developer

I am doing a research project on "Fun and Software Development" in which I kindly invite you to participate.
You will find the online survey under http://fasd.ethz.ch/qsf/. The questionnaire consists of 53 questions and you will need about 15 minutes to complete it.

With the FASD project (Fun and Software Development) we want to define the motivational significance of fun when software developers decide to engage in Open Source projects. What is special about our research project is that a similar survey is planned with software developers in commercial firms. This procedure allows the immediate comparison between the involved individuals and the conditions of production of these two development models. Thus we hope to obtain substantial new insights to the phenomenon of Open Source Development.


With many thanks for your participation,
Benno Luthiger


PS:
The results of the survey will be published under http://www.isu.unizh.ch/fuehrung/blprojects/FASD/.
We have set up the mailing list fa...@we... for this study. Please see http://fasd.ethz.ch/qsf/mailinglist_en.html for registration to this mailing list.

Pyastra project released the first preview release.

This version supports all PIC16* microcontrollers. Many (but not all) of 
python statements are available (see 
http://pyastra.sourceforge.net/STATUS.html for details).

The main goal of this release was to get Pyastra usable. And we hope 
that it was achieved.

Hello,

Current architecture of Pyastra is temporary. First standard python 
module "parser" converts given file to a tree. Second stage is made by 
tree2tree.py optimizer (currently it does nothing at all). Then it is 
converted by tree2asm.py to assembler.

More details is planned to be published at project's homepage near the 
release 0.0.1.

As an example i made a classic example (blinking LEDs):

PORTA=fbin('0101 0101')

while (1):
    PORTA ^= 0xff
    for i in xrange(0, 255):
        pass

It is converted to the following PIC16 assebler code:

	end


And that's the output of Pyastra:

Program memory usage: 30 word(s) (0.4%)
NOTE: statistics includes ICD memory usage!

Hi,
 
I'm interested in finding out more about Pyastra and how it works.  For example, what python code would translate to what PIC code.
 
Thanks,
