Serialise a drawing

  • If I have a paint-like application on a raspberry pi where I can draw on a window, what is the best way for me to serialise what is being drawn and to have it transferred over UART to a second window (on the same raspberry pi) so that the drawing is displayed in real time on both windows?

    As already explained in your other thread you might be taking this the wrong way.

    Thing to determine are:

    • how are both screens connected ?
    • are you using a window manager ?
    • will you be using one or two applications for that ?
    • what technology is each screen's connexion ?
