recording time between events

[spikey1973]

hello to all,

I am fairly new to programming and have been at building a program to get my wemos esp32 s2 mini board to do as I intend it to.
most of it is fairly basic (never the less I still strugg with that is half the fun, not) but now i am a far outside my comfort zone as i don't even know where to start or where to look.

I wish to record time be tween two events..
event 1) = start timer (hardware) as part of a for loop.
event 2a) = end timer upon switch value to go from 0 to 1 -> print the recorded time to a file.
event 2b) = or for the timer to run out a preset time period (7000ms) -> print a string "ran out" to that file instead.

the essence of the problem is the time recording.. printing that information to file is of a later issue.

now i looked at the class Timers, but i can't seem to see hoe i can use this class to denote a time period.
I also googled examples but none of the examples i found relate.. generally it is used delay an event to happen for a certain amount of set time but that is different.

I hope someone here has some experience and can point me towards the right path / some realating examples.

Kind greats

time.ticks

I have seen examples on the old forum:

So, search for "timer ticks"

Hello davefas,

Thank you so much for putting me on this track.. I will go and search for the ticks on the old forum # nolime ;)

Happy new year!!!

more specifically, you likely want to use the time.ticks_diff() function to calculate the difference between two ticks values. It handles timer rollover properly.
