Display a stop watch on the screen

[Tobias]

Hi Julie,

there is no stopwatch function I'd know of, but there might be a way
of implementing one.
If you need an anolog clock, you will probably have to go for bitmaps.
You could make bitmaps for each stopwatch state and then let them run
in a row. Note that the stop watch will not change more often than the
screen can change, e.g. every 10 ms for a 100 Hz screen.

If a digital stopwatch will do it, I guess it is much easier. You just
need a textdisplay with an embedded variable that runs in a loop.

How to exactly implement that also depends on what purpose you need
the stopwatch for. Are participants just to watch it or also react to
the stopwatch?

Cheers,
Tobias
