64KB is more than enough to show notifications and tell the time. Admittedly the bluetooth stack might use most of it (it does on the esp32 at least). Of cours

Of course with that little RAM you also can't keep a full framebuffer so you need more competent developers to drive the display without becoming a flickery mess.
- TT-392 3y agoThere kind of is a full framebuffer in the display driver chip. You just tell it to draw a square somewhere, and the square will stay there. One of the most limiting factors of the display is actually the spi bus to the display, only running at 8MHz, allowing a maximum full screen update speed of like 8 fps.
