Oled character displays

[dsaito]

Thank you so much for adding this library for the Ruby language. However, I'm wondering if the library also supports 16x2 and 20x4 OLED character displays. It seems Adafruit has updated their libraries more recently to add support for such displays. Keep up the good work!

Oh, thanks for letting me know.
Maybe I need to order those components to see if it also works on them.
I don't think there will be big differences though :-)
