pystrobe is a strobe tuner emulation for Python S60 3rd Ed. This is a preview release, v0.1 will start once everything gets cleaned up. See it in action

Installation

1. Install PyS60 and Python shell if you don't have them yet. (Tested on PyS60 v1.4.4, may not work on newer versions.)
2. Download and install audiostream_selfsign_testrange.sis
3. Copy pystrobe.py to c:\Python or e:\Python

Usage

Launch Python shell then run pystrobe.py

Keys

• Up/Down - change octave
• Left/Right - change note
• Select - toggle pitch detection
• '1' - toggle noise filter
• 'star'/'hash' - cents offset
• '0' - reset cents offset
• '2' - switch to other applets (currently under development)

Issues

• This application uses the deprecated UserSvr::ScreenInfo method of screen drawing (graphics.Draw() is too slow).
• Audio streaming may not work properly on some devices due to differences in audio and graphics hardware (works on E65 and N73, may work on other OMAP1710 based devices, does not work on N95, 6120/6121).
• The audio streaming thread does not terminate upon exiting the application.
• Python shell may have more capabilities than NetworkServices LocalServices ReadUserData WriteUserData UserEnvironment, in this case import audiostream will result in KErrPerimsionDenied.
• You may encounter compiler errors not recognizing ARMv5E instructions like smulbb. Include the following line in audiostream.mmp:

  OPTION GCCE -march=armv5te -O2 -fomit-frame-pointer -fno-unit-at-a-time

TODO

• Create proper Python extension objects
• Cleanup, document, ...
