hi bill,
thanks for your reply.
to use the i2c bus is very interesting. i´m a arduino beginner, so it seems a little bit difficult at first sight.
also to purchase the MCP23017 is not that easy in germany.
i ll try to get one.
my glcd type is a CFAG12846B-TMI-V
i hope the code will work with that kind of glcd type too
what do u think?
