Hey there, does sharing the screen to Mac require some kind of cloud sync? If so, is there any noticeable delay from sketching on the device to appearing on Mac?
I wrote pipes-and-paper[1] which sort of shares your screen without any cloud.
Getting to what the display puts out is difficult, but recording the pen strokes isn't.
So what I wrote is a small webserver that runs on the reMarkable (1 and 2) that sends the penstrokes to the webbrowser via Websockets.
It draws all penstrokes on a camvas in the browser and also deletes strokes when the eraser is used.
