I got my new ESP-01's up and running - so, the modules are fine and programming (w/ IDE 165) works.

However, the following code (which runs flawless on the uno), compliles fine for the ESP, but throws an error and crashes when running on the ESP:

Code: Select all void loop() {
  for(x = 0;x < loopmaxcount; x++) {  // accumulate batch of timestamps
    // Update the Bounce instance :
    debouncer.update();
    // compare the reedState to its previous state
    if (debouncer.fell()) {
      ++GasCounter;
      Serial.println(GasCounter);
      timestamp[x]=now();
    }
    else {
      x--;
    }
  }
.........

This is the error popping up on the serial monitor:

Code: Select allSoft WDT reset

ctx: cont
sp: 3ffef900 end: 3ffefb40 offset: 01b0

However, when I eliminate the else part from aboves code:

Code: Select all    else {
      x--;
    }

the code runs!

Pls note: I am not a programmer, so the code is probably not elegant, but I do not see how to do it different.... (*)

Any help would be greatly appreciated!

(*) Basically, what I want to achieve is:
I am monitoring a switch on gpio02; whenever that switch is closed, I want to store the timestamp of that event into an array timestamp[x], where xmax is 10. I do this in a for x= 0 to 10 loop, but whenever there is no switch event detected, I decrease the loop variable by one. So the loop hits only the max count of 10, when there where 10 events detected. After that, other code is run (-> transmitting the 10 timestamps via wifi to a server)

Thanks for the quick answer, Pablo2048!
That did the trick!
Excellent.
