I was able to resolve the issue I was having with your fb and pygame examples. I had to ensure the BUS was set to '0' and the pin GPIO values were set properly in 'on.sh'. The same was true in reset.sh with 'busnum=0'
Also, it seemed that if I ran the examples in 'usr', I had to reboot the board for the 'fb' examples to work. It's all working now. Nice job.
