WebIt waited for 5ms, then last measurement=0+5=5 ms. Then it’ll do analogRead (). Let’s say analogRead () took 10ms, then mills ()- last measurement () = 15-5 ms=10 ms so the loop will do another analogRead () although it’s not reading measurement exactly after 5 ms. So this will only work if loop execution time is <5ms. – Talha Yousuf. Web27 jun. 2024 · Very odd. I think the fundamental issue is that your current_state variable doesn't match the actual current state of your routine. Generally you should enter that state and set current_state at the same time, not set current_state to the next desired state and try to handle initialising and polling it in the same context.
