Arduino Energy Saving Library


Energy Saving library provides you to manage power on Samd boards. This library can standby microcontroller and wake-up it by external interrupt or alarm match interrupt. During standby, the board drawing very low current from power supply, about 2 mA. This value seems not too low but consider the presence of switch regulator on the board because it is always active.


This library has two constants.

WAKE_EXT_INTERRUPT:indicates that MCU wakes up by external interrupt

WAKE_RTC_ALARM: indicates that MCU wakes up by alarm match rtc interrupt.
