config EXAMPLE_TOUCH_WAKEUP
bool "Enable touch wake up"
default y
depends on !IDF_TARGET_ESP32C3
help
This option enables wake up from deep sleep using touch pads
TOUCH8 and TOUCH9, which correspond to GPIO33 and GPIO32.
config EXAMPLE_ULP_TEMPERATURE_WAKEUP
bool "Enable temperature monitoring by ULP"
default y
depends on IDF_TARGET_ESP32
help
This option enables wake up from deep sleep using ULP.
ULP program monitors the on-chip temperature sensor and
wakes up the chip when the temperature goes outside of
the window defined by the initial temperature and a threshold
around it.
config EXAMPLE_EXT1_WAKEUP
bool "Enable wakeup from GPIO"
default y
depends on !IDF_TARGET_ESP32C3
help
This option enables wake up from deep sleep from GPIO2 and GPIO4. They should be connected to LOW to avoid
floating pins. When triggering a wake up, connect one or both of the pins to HIGH. Note that floating
pins may trigger a wake up.
config EXAMPLE_GPIO_WAKEUP
bool "Enable wakeup from GPIO"
default y
depends on IDF_TARGET_ESP32C3
help
This option enables wake up from GPIO, only GPIO0~5 can be used to wake up. Be aware that if you use low level
to trigger wakeup, we strongly recommand you to connect external pull-up resistance.

help
This option set the gpio wake-up trigger signal, In deep sleep, only high or low level wake-up is
supported. If this option is enabled, it is a high level wake up, otherwise it is a low level wake up.
