Add config and overlay to samples for testing stop/standby modes: - samples/boards/st/power_mgmt/blinky - samples/boards/st/power_mgmt/wkup_pins I've measured consumption for each low-power mode: - stop (regulator in run mode) ~217 uA - stop (regulator in low-power mode) ~206 uA - standby mode ~3.5 uA Low-power mode wakeup timings from the datasheet, but it barely meets these in reality: - stop (regulator in run mode) 3.6 us - stop (regulator in low-power mode) 5.4 us - standby 50 us It's possible to use RTC as idle timer to exit from stop mode.
