PiBox

It works well on rpi2. I just need to test it on rpi hardware.

Then I can enable these lines in config.txt to get better color depth:

@@ -27,6 +27,10 @@ overscan_bottom=32
 #framebuffer_width=1280
 #framebuffer_height=720

+# If using fbturbo, get more color with these.
+# framebuffer_depth=32
+# framebuffer_ignore_alpha=1
