New Haven 2.7 oled with ssd1322 about luma.oled HOT 4 CLOSED

I never had access to a newhaven device to test against. I believe it was introduced in #245 … @doug-burrell might be able to provide some insights/context?

I'm sorry but I no longer have access to this hardware and can't remember the logic behind how it worked.

It is pretty unusual and makes the bitmap authoring prior to send to display a bit weird, but electrically I can see maybe why they do it - and their example code on newhaven indicates that they do indeed use two adjacent seg to drive one pixel. For black and white the approach would have worked identically - ie 0xFF or 0x00 would have resulted which would have looked ok. It's just the greyscale that would have been odd with low order bits somewhat randomizing the greyscale drive, and even then it probably looks ok in some circumstances. depending on the exact values.
