Going through the list of interrupt vectors related to air/interrupt.h in the on-line libc documentation at nongnu.org, there is no listing for Mega328 or any of its variants for TIMER/COUNTER2 Compare Match A! There is for M48, M88, M168, but NOT M328! TIMER2_COMPA_vect appears to work (e.g., compile without a posted error and function in a running program). But, its not there in the list.
Same appears to be true for TIMER2_COMPB_vect. Thanks for everyone’s work on this!
