Graphical Displays with PBP3

[richard]

Your lib file looks more like an example file. Is it correct ?

it is. it's the driver component to enable my graphics library to use a sharp memory display.
post #1 has typical use demos!

update to ssd1306 include to allow easier configuration for 40x72 displays

Nice and useful addition to a very handy include file.

Though I wonder up to what age you can read that displays without eye glasses...

Though I wonder up to what age you can read that displays without eye glasses...

that's kinda the purpose of this universal graphics method, fonts for it of a good size are simple to make and interchangeable
between versions and displays.
a 5x7 font on that display needs a magnifying glass and eye glasses for me.
note i used a 18x39 font to test with. that i can read from many metres away easily
