This was just a visual test with slow display code (don't remember the frame rate). Expanding a 64 x 64-2bit display to 128x128 4-bit is doable in ~9.3msec @ 60fps that would take ~56% CPU time on AVR @16MHz. Plans are to use the new atmega4809 @20MHz (I just like 8-bit) so there's a full frame buffer for 128x128 -2bit and display update is slightly faster.
Just a discription: 128x128 1.5inch SPI OLED display, controller SSD1327, This module is Waveshare brand. There are I2C versions too but those are too slow to update
What a beautiful display!
Maybe just green woukd allow better battery
WOOOOOW ... OMS
Wow 😮
Did you get any further with this project? What is the screen refresh rate please? Thanks.

@@MrBlinky What library did you use to display these bitmaps please?
@@MikeMcRoberts Didn't use/write a library. just some display setup code and write 1k image data.
Is there a part number?
