Second, a trackball proof of concept. I don't have one myself so I can't
test it out. Again, a DLI is used to sample the trackball multiple times
per
screen.
Which Trakball does your program read, the CX-22 or the CX-80?
And how often do you sample new data? In my experiments with the
Trakball on the 2600 I found that you'd need at least 20 values
per frame for a smoothly moving cursor.
I'm also planning on doing one for the driving controller. I just have to
figure out Thomas's code from StellaList and make it work for both
players.
The driving controller works the same way as the CX-80 Trakball
(wich is the same as the ST mouse, BTW). But it only has one axis
and a much lower resolution. So, if your demo is programmed for
the CX-80, it should work with the driving controller too.
Ciao, Eckhard Stolberg
