My goal is to use an M5Paper as a drawing tablet. Either through capturing strokes, lines, and/or pixels.

Some questions:

• how fast is the response of the GT911 capacitive touch screen? quick enough to do sketching/drawing input?
• is there a suitable (active?) stylus that will work on the touch screen?
• would partial screen redrawing help?

Any thoughts, examples or assistance great appreciated.

Thanks!
