looks like you can use interrupts in bonescript (which is javascript?) on the beaglebone: http://beagleboard.org/support/BoneScript/attachInterrupt/ other search hits talk about writing a kernel module, which would be more hardcore: http://derekmolloy.ie/kernel-gpio-programming-buttons-and-leds/#Interrupts 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. -jake On Mon, 2 May 2016, Cere Davis wrote: 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.
