os-pimonitor

os-pimonitor is a display solution to show the OpenSong presentation image on a monitor using a Raspberry Pi - or as a matter of fact, any hardware platform that runs Python and offers a framebuffer interface. It shows the slide that is currently presented full-screen on the monitor. It can be used to easily setup an preview monitor or a presentation screen at location where installing a VGA or HDMI cable is not viable. The os-pimonitor uses the internal WebSocket server of OpenSong and only requires bandwidth when a slide change occurs. This makes this solution work very well over WiFi.

The OpenSong PI Monitor is a readonly client for the OpenSong API. It can not be used as a remote control for OpenSong.

The features are:

• display of the current slide as image on the attached monitor
