hi Priyanka

[quote userid="107729" url="~/f/nordic-q-a/85806/how-to-set-2-separate-callbacks-on-the-same-pin-for-pin-raise-and-fall-in-zephyr/358663#358663"]you could try to use the GPIO_INT_EDGE_BOTH and check the pin state in the callback maybe.[/quote]

that is what i have done but if i remember correct nrf sdk dose allow to have 2 callbacks on same pin one for ACTIVE_HIGH and one for ACTIVE_LOW

i understand from your answer that it is not the case with zephyr

ok, thanks Priyanka

Hi Ziv,

This is not possible to implement as the flags are configured per pin and not per callback. It is possible to add multiple callbacks for a single pin, but only one interrupt configuration can be used for the pin. But, you could try to use the GPIO_INT_EDGE_BOTH and check the pin state in the callback maybe.

You can take a look at few examples:
