SSD1306 OLED (72x40) I2C display from scratch

I have a quesiton - 24C64 or something like that costs under $1. Why not use it for font storage

because you can save your $1 and another one by buying a better pic to start with and :-

not have a costlier more complex circuit board .
use a standard font file generated by glcd font creator.
its faster, uses hardware i2c and can do proper graphics too.

as i said at the beginning if you want easy get a pic 18
