Anyone actually using hardware timers?

We have a scheduler based on the hardware timers. It allows scheduling of events at regular intervals, or single shot events at some time in the future.

It uses function pointers to allow the scheduler code to avoid needning to know what functions it may be calling.

What kind of things are you scheduling?

Anything that needs to be called on a regular basis. For example, a regular sensor reading that is faster than the 26ms loop, but not "as fast as possible".

It seems like timers are a problem for a lot of teams so I posted ours this morning on this thread in the wrong place... I didn't see the rest of the thread or that the issue was already solved.

It sounds like you have taken a similar approach with event timers that call routines when they time out. After all when all your other sensors have failed or you should still at least have timers! The example shows one way to estimate processor loading which also seems to come up a lot.
