See docs/deep-sleep-stub.rst for details.
void esp_set_deep_sleep_wake_stub(esp_deep_sleep_wake_stub_fn_t
Install a new stub at runtime to run on wake from deep sleep.
If implementing esp_wake_deep_sleep() then it is not necessary to call this function.
However, it is possible to call this function to substitute a different deep sleep stub.
used as a deep sleep stub must be marked RTC_IRAM_ATTR, and must obey the same rules given for
esp_wake_deep_sleep().
esp_deep_sleep_wake_stub_fn_t
Get current wake from deep sleep stub.
Return Return current wake from deep sleep stub, or NULL if no stub is installed.
void esp_default_wake_deep_sleep(void)
The default esp-idf-provided esp_wake_deep_sleep() stub.
See docs/deep-sleep-stub.rst for details.
void esp_deep_sleep_disable_rom_logging(void)
Disable logging from the ROM code after deep sleep.
Using LSB of RTC_STORE4.
void esp_sleep_config_gpio_isolate(void)
Configure to isolate all GPIO pins in sleep state.
void esp_sleep_enable_gpio_switch(bool enable)
Enable or disable GPIO pins status switching between slept status and waked status.
Parameters
• enable: decide whether to switch status or not
Type Definitions
typedef esp_sleep_source_t
typedef void (*esp_deep_sleep_wake_stub_fn_t)(void)
