//| """Light and deep sleep used to save power
|
|
//|
|
|
//| The `sleep` module provides sleep related functionality. There are two supported levels of
|
|
//| sleep, light and deep.
|
|
//|
|
|
//| Light sleep leaves the CPU and RAM powered so that CircuitPython can resume where it left off
|
|
//| after being woken up. Light sleep is automatically done by CircuitPython when `time.sleep()` is
|
|
//| called. To light sleep until a non-time alarm use `sleep.sleep_until_alarm()`. Any active
|
|
//| peripherals, such as I2C, are left on.
|
|
//|
|
|
//| Deep sleep shuts down power to nearly all of the chip including the CPU and RAM. This can save
|
|
//| a more significant amount of power, but CircuitPython must start code.py from the beginning when woken
|
|
//| up. CircuitPython will enter deep sleep automatically when the current program exits without error
|
|
//| or calls `sys.exit(0)`.
|
|
//| If an error causes CircuitPython to exit, error LED error flashes will be done periodically.
|
|
//| An error includes an uncaught exception, or sys.exit called with a non-zero argumetn.
|
|
//| To set alarms for deep sleep use `sleep.restart_on_alarm()` they will apply to next deep sleep only."""
