1 .. zephyr:code-sample:: esp32-deep-sleep
4    Use deep sleep with wake on timer, GPIO, and EXT1 sources on ESP32.
14 make use of that pre-configured wake up source to bring the system back again.
18 1. ``Timer``: An RTC timer that can be programmed to trigger a wake up after
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
24    GPIOS0~5 can be used as wake-up sources.
26 In this demo, Timer is the only wake-up source that cannot be disabled via a
27 Kconfig option. The target SoC will always repeat the following: enable Timer
28 as wake-up source, deep sleep for 20 seconds, wake up.
35 only ``Timer`` is used as wakeup source.
37 However, when ``EXT1`` is also enabled, GPIO2 and GPIO4 should be pulled-down
38 by external resistors to avoid floating pins. When triggering a wake up, one
43 enabled as wake-up source.
