Accurate timing?!

[hydroo]

Hi,

I am thinking about creating a game for rockbox.
I have been playing around a bit, and have some questions.

Is there kernel-timer ("current_tick" reliable? - steady and 100 ticks/sec ?)

Are there platformdifferences?

Can the tickfrequency change?

What would be the best way to get a steady, accurate clock?

(I am using the sansae200, if that matters)

regards

Yes, the tick timer is reliable, and it ticks with HZ ticks per second (currently 100, not likely to change)

There is also a possibility to use one of the hardware timers if you need better resolution.

All targets have the same tick timer, but not all have available hardware timers to use.
