Low Power Management for RP2040: In lightSleep we just reduce the processor system clock and voltage. In deepSleep we actually set the processor as dormant, but we must choose between the wakeup by a pin or a timer based wakeup. Only one single wakeup gpio pin is supported! More...

Public Member Functions | |
| bool | isProcessingOnSleep (sleep_mode_enum_t sleep_mode) |
| Returns true if processing is possible in the current sleep mode. | |
| bool | sleep (void) override |
| sets processor into sleep mode | |

| Defines the wakup pin. | |
| void | clear () |
| reset the processing | |
| void | setRestart (bool flag) |
| We force a restart after we wake up from sleep. | |
| virtual bool | sleepFor (uint32_t time, time_unit_t time_unit_type) |
| sets mc into sleep mode to sleep for indicated millis | |
| virtual void | setActive (bool flag) |
| sets the flag to be active | |
| virtual void | setActiveTime (uint32_t time, time_unit_t time_unit_type) |
| Defiles the active time. | |
| virtual bool | isActive () |
| Checks if we are active (not sleeping) | |
| virtual | operator bool () |
| same as isActive() | |
| virtual bool | setSleepMode (sleep_mode_enum_t mode) |
| Defines the sleep mode. | |
| virtual void | process () |
| Triggers the processing to be active or sleeping based on the set definitions. | |
| virtual bool | isProcessingOnSleep () |
| Returns true if processing is possible in the current sleep mode. | |
| virtual bool | isModeSupported (sleep_mode_enum_t sleep_mode) |
| Provides information if the indicated mode is supported. | |

Detailed Description
Low Power Management for RP2040: In lightSleep we just reduce the processor system clock and voltage. In deepSleep we actually set the processor as dormant, but we must choose between the wakeup by a pin or a timer based wakeup. Only one single wakeup gpio pin is supported!
