GPIO wake up on any low

Postby kostyan5 » Tue Jul 09, 2019 2:30 pm

In our design, we have 2 components that have an active low output and we'd like to use either of those lines to wake up ESP32 from deep sleep. EXT1 source supports wake up for ANY HIGH or ALL LOW. I was wondering if there is a way to enable ANY LOW functionality for EXT1 wake up. I realize we can just add an inverter to each device output but I would prefer that to be the last resort.

Thanks,

Konstantin
