4 Use deep sleep with wake on timer, GPIO, and EXT1 sources on ESP32.
13 This sample shows how to set a wake up source, trigger deep sleep and then
14 make use of that pre-configured wake up source to bring the system back again.
16 The following wake up sources are demonstrated in this example:
18 1. ``Timer``: An RTC timer that can be programmed to trigger a wake up after
19 a preset time. This example will trigger a wake up every 20 seconds.
20 2. ``EXT1``: External wake up 1 is tied to multiple RTC GPIOs. This example
21 uses GPIO2 and GPIO4 to trigger a wake up with any one of the two pins are
23 3. ``GPIO``: Only supported by some Espressif SoCs, in the case of ESP32-C3

11 This option enables wake-up from deep sleep using GPIO2 and
12 GPIO4. The sample enables internal pull-down on EXT1 pins to
13 avoid random wake-ups. Otherwise, external pull-down should
14 be used for the same purpose. To trigger a wake-up, connect
22 This option enables wake-up from GPIO. Only GPIO0~5 can be used
23 as wake-up source. Be aware that when low level is used to trigger
24 wake-up, an external pull-up resistance is necessary.
