This program activate two relays with web interface and real pushbuttons. In debug mode the program works ok but in run mode when i push button with interrupt 14 and button with interrupt 12 the relative relay go on for one second and go off, why?

Hi Miloit,

What does your schematic look like? Do you have pullup resistors (10K or so) on all the inputs that are defined with interupt?

I have not tested your code but I would suggest you drop back and simplify it as much as possible and see how it behaves. Like just set up with one relay and one INT and then start moving forward adding more complexity and see where it breaks.

good luck

Thanks for the quick reply heckler. Yes i have pulled a 10k resistor on every pin except D0 and D2.
I do not understand why program run well in debug mode and bad in run mode...

I might be wrong, but I thought there was only 1 interrupt available (and similarly only 1 timer), which could therefore only be attached to one pin at any one time.
In which case your script keeps re-defining the single interrupt to different pins, and only the last defined interrupt pin assignment will actually cause an interrupt, rather than having multiple pins each with their own interrupts as you were presumably expecting.

If that's the case, you would either need to keep polling the pins for change...
or perhaps use a multi-i/o port expander for your inputs, and have a port expander input change cause its interrupt output to trigger the esp's single interrupt pin to branch to an interrupt handler routine that would read the port expander inputs for what changed.
