#99870 - What does "timing" mean? Responding to: ???'s previous message |
What are you both defining as "timing dependent"?
Erik Malund said:
"5) anything timing dependent that is not interrupt based is outlawed. " To which Russell Bull said:
In my extensive experience and reading, suggesting that timing must be reliant on interrupts has no base. "timing" can have many aspects and definitions in this context. If "timing" means "timely response", then interrupts are a good facility to have (presuming that one designs their response to be timely). If "timing" means "accuracy of waveform (re)production", then interrupts can perturb a software-timed means of producing said waveform. ISR's are not "free of baggage". |
