This example for the Arduino Primo board shows how to use
7+
stm32pwr library.
8+
The STM32 has two functions for power savings. One is sleep mode,
9+
and the other is standby mode. The USER1 BUTTON allows you setup
10+
as an interrupt to trigger STM32 enter to sleep mode or wake up
11+
from sleep mode. When the Primo board is powered by USB cable and
12+
battery, and then disconnect the USB cable, the STM32 will enter
13+
to standby mode or the Primo board is only powered by battery.
14+
Waiting for Primo board reconnect to USB cable to wake up from
15+
standby mode. The disableStandbyMode() function allows you to
16+
disable STM32 enter to standby mode when the Primo disconnect
17+
the USB cable.
18+
19+
This example code is in the public domain.
