Re: Pin behaviour in case of chip defect

Then the additional chip can fail... I am a little bit stuck... Then i will follow this way of thinking and i will ask, do you have fail safe in case of transistor fail, or selenoid, bad soldering, or just a wires? Everything may pass quality tests, but after some time fail. In other hand esp32 is ...

This is only theory, but: - esp_sleep_get_ext1_wakeup_status is reading latched register, - that latched register stores values for all pins being high during wakeup and being setup as wakeup pins, - since it is big button with some bigger debounce it is possible that button during reading and latch...
