SleepMode

enum class board::SleepMode : uint8_t

strong

Defines all available sleep modes for ATmega328P.

Enumerator
IDLE	In this mode, CPU is stopped but all other peripherals and interrupts work normally. In this mode, current consumption is reduced to about 25% of active mode consumption.
ADC_NOISE_REDUCTION	In this mode, CPU is stopped but other peripherals and interrupts work normally, except IO. This mode is actually very similar to IDLE.
POWER_DOWN	In this mode, everything is stopped (including oscillator) but external interrupts, I2C slave (if enabled) and Watchdog Timer (if enabled). This is lowest current consumption mode, typically a few uA, depending on other factors (voltage, watchdog enabled or not). Waking up from this mode may take significant time until internal oscillator is restarted and stabilized; refer to datasheet for more detailed data (look for Start-up times).
POWER_SAVE	This mode is similar to POWER_DOWN, except Timer2 is still running if enabled. Waking up from this mode may take significant time until internal oscillator is restarted and stabilized; refer to datasheet for more detailed data (look for Start-up times).
STANDBY	This mode is similar to POWER_DOWN, except the oscillator is kept running, hence waking up from this mode takes only 6 clock cycles.
EXTENDED_STANDBY	This mode is similar to POWER_SAVE, except the oscillator is kept running, hence waking up from this mode takes only 6 clock cycles.

Function Documentation

init()

static void board::init ( )

inlinestatic

Performs special initialization for ATmega328P, actually nothing at all.

This must be called first in your main() function, even before sei(). In general you should ALWAYS call this function at the beginning of your main() even if you know it will not do anything; this will prevent strange behaviors when you want to port your code to another MCU target for which init() does perform important initialization, e.g. ATmega32u4 (Arduino LEONARDO).
