ATtiny85 + bitmap + OLED

Hi, @undefined0x0
Welcome to the forum.

Please read the post at the start of any forum , entitled "How to use this Forum".

Have you googled;

attint85 oled

You will need an I2C Oled display, however I would doubt if a button cell would be able to power the project or last very long.

Can you tell me the application?

Thanks.. Tom... :smiley: :+1: :coffee: :australia:
