Why not to use default "Conversion completed" interruption?
can't find any arduino examples
There are some examples for using Noise Reduction (which is sort of related). I can't find anything about asynchronous reads either.
@robtillaart: Would auto-triggering with a ring buffer be useful? Analog readings would be collected (and timestamped) continuously in the background. The application would pull readings from a shared ring buffer. I think managing multiple channels is the only tricky part.
