After being nearly one year with no news from the project, the libam7xxx library that drives various USB pico projectors on Linux has been updated.
This is a third-party project to power small USB-based mini projectors under Linux
. Among the supported USB projectors are the Acer C110, Acer C112, Aiptek PocketCinema T25, Philips/SagemCom PicoPix 1020, and the Philips/SagemCom PicoPix 2055.
Aside from new device support, there's also a MinGW-based Windows port, support for setting the projector's zoom mode, multi-device support (driving multiple USB projectors simultaneously), and other changes.
