Thanks

I know Yocto isn't an RTOS - That (plus experiments) is why I cautioned readers about the Edison module's interrupt processing abilities. Having an RTOS isn't the only thing that determines whether a computer will do well at processing interrupts at a given arrival rate, but you are right that the OS architecture is a big part of the job (and don't forget that many (most?)(all?) Linux implementations can be customized to make then leaner and meaner (sometimes the off-the-shelf mods can include making RT deadline guarantee changes), if you like digging into that sort of stuff).

When I last checked, there wasn't an officially-supported RTOS (by Intel/WindRiver or anyone else)for the Edison's two dual-core CPUs or for it's third CPU (a Quark?). That was a few months ago, and things may have changed since I last looked. Do you have any recent news?

A colleague is attempting to use that third CPU for catching encoder interrupts for a project he and I are working on, but he hasn't declared victory yet (and he is travelling right now). He would be one source of info I could try to tee up for someone who wanted help. He says he is using info he got from Intel, but I *think* what he is using are preliminary APIs/libraries, etc, plus advice gotten through Q&A discussion forums.

PS: Don't forget that we should at least mention CAD files in each post in this thread. <-- I just did.
