Hi Bean;

Now wait just a minute...... there is nothing "messy" about interrupts. It permits you to do things exactly and deterministically. In fact, I bellieve it to be the ONLY way to code time related programs...... I would never stoop to using a "pause" (OK, perhaps a few NOPs for a few cycles) to wait for anything. With interrupts, (simple) multi-tasking is a breeze, and pre-emptive multi-tasking is very achievable in an SX28.

That said, with the exception of the PAUSE function, I do like what you have done with SX/B. You can get a lot done with only a little effort. It appears to be well respected for non time-critical applications, and has garnered quite a following. For real-time multi threading however, something more substantial is required employing those darned "ISR's", and that's the field where I like to "mess".

Keep up the good work.

Cheers,

Peter (pjv)
