The edge type can be one of three … NettetBut when using INT_EDGE_FALLING the interrupt seems to be called continuously as the code is printing an endless string of '.'. This rather looks like a level interrupt than an edge triggered one. The GPIO is configured in my software only and the internal pull-up is enabled so I can be sure that it is not floating.

Nettet21. mar. 2024 · The INT0 interrupts can be triggered by a falling or rising edge or a low level. . . . This also makes it clearer, again from the datasheet Ch 9.2: Note that recognition of falling or rising edge interrupts on INT0 requires the presence of an I/O clock The clock is not running in this sleep mode. Nettet17. mai 2024 · Its exactlly what is says. If edge interrupt is set, the ISR will only get fired on falling/rising edge of a pulse. While if level sensitive interrupt (as you say) is set the ISR will get fired everytime there is a low-level/high-level signal on the corresponding pin.
