How do I use PiScreen with XBMC?

PiScreen isnt supported on XBMC.  However there is a work around to copy what is display on the HDMI port(fb0) to the PiScreen.

 

To do this, we will need Framebuffer Copy.

pi@raspberrypi ~ $ sudo apt-get install cmake
pi@raspberrypi ~ $ git clone https://github.com/tasanakorn/rpi-fbcp
pi@raspberrypi ~ $ cd rpi-fbcp/
pi@raspberrypi ~ $ mkdir build
pi@raspberrypi ~ $ cmake ..
pi@raspberrypi ~ $ make
pi@raspberrypi ~ $ sudo install fbcp /usr/local/bin/fbcp

To use Framebuffer Copy the console needs to be on fb0. If it isnt already there, you can change it to fb0 using this command;

pi@raspberrypi ~ $ con2fbmap 1 0

The run framebuffer copy in the background

pi@raspberrypi ~ $ fbcp &

You should now have fb0 mirrored onto fb1(PiScreen).
