It depends on what latency you want. The CVS can poll looking for a
state change on the input. You can do this on any analog input by
doing an ADC, but since the input is binary, you could treat this as
a digital input as long as the input signal has the appropriate
amplitude to read as a logical 1 when divided by two which is the
input stage gain. You have to figure out if the latency is
tolerable. Certainly the Aux input can be polled quickly.
Alternatively, I wrote some code that is in my template that can
generate interrupts on edges for the Aux input, so you can have very
little latency. I wrote this so I could detect triggers. My
triggers are fast, and if occur when the processor is busy elsewhere
in the code, are missed. Edge interrupts always guarantee they are
sensed.
