picoDesk

Send desktop or selected applications window to a USB LCD. The USB LCD must support bulk write and accept a buffer with the image as input. For adding more LCD types see lcdusb.c.

It should work with any NETWM compatible window manager and implements EWMH Specifications. With XDamage extensions it tracks changes to the window content and updates the output. The final image of multiple windows content is composed with xcomposite/xrender and then encoded as a buffer for usb lcd using the code in mbl_encoder/.
