After almost one year of fixes and new functionalities here is libam7xxx-0.1.3.

libam7xxx is a library to communicate with USB pico-projectors like, for instance, the Philips/Sagemcom PicoPix devices; you can read more about it in the previous stories:

• On USB projectors, linux and libam7xxx
• An Open Source driver for USB pico projectors

The devices supported in this release are:

• Acer C110
• Acer C112
• Aiptek PocketCinema T25
• Philips/SagemCom PicoPix 1020
• Philips/SagemCom PicoPix 2055

With this release PicoPix 1020 and 2055 are finally fully working, thanks to the people who helped fixing and testing the code, here is the entry from the NEWS file:

News for v0.1.3:
================

  * Better documentation
  * Ported to Windows (compiles with MinGW)
  * Added a minimal replacement of usb-modeswitch to use on systems where the
    latter is not available
  * Added support for Acer C112 (Thanks to Richard Wisenoecker)
  * Added support for Aiptek PocketCinema T25 (Thanks to Matti Koskinen)
  * Added some contrib scripts
  * Added support for setting the projectors zoom mode
  * Added multi-device support, now more than one projector can be used at the
    same time on the same system (Tested by Konstantin Lohmann)
  * Added support for Philips/SagemCom PicoPix PPX 2055
  * Fixed some problems with the supported Philips/SagemCom PicoPix devices,
    now these devices are fully working (Thanks to the Certik family)

Debian packages for i386 and amd64 are available at ao2.it/debian.

If anyone knows people at Sagemcom, would you put me in contact with them? They didn't reply to my previous messages to their support service address. I'd like to ask if they may be interested in providing some test units or to sponsor some development-time to make the pico-projectors work on Android.

Here is the shortlog between v0.1.2 and v0.1.3 for those interested in the development details:
