Hello soykmw,
to detect rising/falling edges of TTL signals (= boolean signals) you can use the 'Implies' operation (or even better: Compound Arithmetic) from the boolean palette together with a shift register (for recalling the last iteration's value) in the while loop. Well, that's a basic boolean operation
