LilyGO ePaper ESP32 can wake up the device only if the button is HIGH, then it is possible to trace which GPIO was used via the button.
Unfortunately I have a device with LOW buttons and unfortunately ESP_EXT1_WAKEUP_ANY_LOW cannot be used there, only ESP_EXT1_WAKEUP_ANY_HIGH.
Is there a way to use ESP_EXT1_WAKEUP_ANY_LOW? Maybe ULP? Has anyone ever encountered this and solved this problem in software?
What??? I do not have a clue what you are asking. Start with a block diagram and links to technical information on all the hardware devices. If you have wired this post a schematic showing how it is wired. Also if you have written any code post that as well.
