Wow, 64 KB of RAM. That’s incredibly tiny for all that the device needs to do.

- tredre3 3y ago64KB 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 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.

- eternityforest 3y agoI almost got one, but I decided to get a Wear OS instead and love it. I still occasionally think about getting one, but not to use as a watch, it just seems like it has lots of potential for other things. I could attach it to something and have it send motion sensor alerts to my phone, or it could be a remote input device.
