anita2R Nice Work!
I plan to look at your code in detail to learn something new about the RPI. I have used the chipKIT UNO32 with a Sparkfun I2C backpack.
How does the 4/8 bit mode stuff come into play over an I2C backpack interface? I thought 4/8 bit mode related to using a 4 or 8 bit parallel interface. This should be handled by the backpack processor.
I think RPI users could be a source of new Perl users. More posts like yours might help this along.
Update: After reading your code it appears that the SainSmart LCD you are using has a much lower level interface than the Sparkfun unit that I used. The Sparkfun backpack hides all of the bit manipulation from the user.
There's never enough time to do it right, but always enough time to do it over...
