HI,
I also have a question about display speed... Now I have bought display module with ST7735R and it has SPI connection. great because not so much wires are required...
But I have spotted very lack of speed in complete display redraw (or of huge areas). Full display rewrite can take about 2 second (I guess, but it is well seen). This write speed is really insufficient in my project - is it caused by limits of SPI bus or library optimalization ?
Am I right guessing that display on parallel connection redraws whole display area much faster?
I looked on video on first post - display seems to redraw faster and as I see a lot of wires it should be parrallel connected...
