Timer API

[thejpster]

An interesting question came up.

How can applications register for a regular timer "tick" - a function they provide which is called by the OS in interrupt context periodically?

I wonder if there could be an API for a timer device with period (rw), base_freq (r), address (rw) and enable (rw).

You could do a similar thing for vertical blanking interval interrupts.

The SDK could help, checking you have an extern "C" function and so on.

Or you could create timer objects that need polling. It's not like there are any other tasks to run.
