I'm thinking more about the semi-default level of interrupt programming that is inherent in the OS itself.  If I just code with python on the linux side, I have some level of interrupt programming already baked in from the linux kernel.  I don't need to be absolutely real-time for the interrupts but would like to be more real-time for the Arduino micro controller side, just mostly trying to figure out if there is a simpler way to skin this cat, as the old saying goes.

looks like you can use interrupts in bonescript (which is javascript?) on the beaglebone:

other search hits talk about writing a kernel module, which would be more hardcore:

i guess it depends how time-sensitive is your application, and what level of coding you want to engage in.  I don't know about raspi, i hate them.

hopefully someday soon you will be able to get a beaglebone black out of the vending machine in sudoroom.

Hi Folks,
I have an interactive real-time hardware project where I am wanting good (non headache coding) interrupt processing that also has good rt support.  I was hoping to leverage
the easier function of a linux micro controller like Beaglebone for the interrupt side, with a connected Teensy for better RT function.  Yet, I haven't seen many people do
this and I am worried that I don't really understand the devil in the details about the tradeoffs well enough.  

Are there ppl on this list that build projects with these kinds of interactive real-time demands that can help me sort through the best choices during some hack night?

Thanks,
-Cere
