General comments: Compiling this code out-of-the-box will result in a 320x240 interpretation of the framebuffer contents. To achieve a 640x480 resolution, uncomment the loadFrameBuffer_640x480 function call, comment the loadFrameBuffer_320x240 function call, and re-compile. The raspberry pi framebuffer settings in /boot/config.txt must be configured for consistency with the specified resolution.
