# Deep Sleep Mode Example # This example demonstrates the low-power deep sleep mode plus sensor shutdown. # Note the camera will reset after wake-up from deep sleep. To find out if the cause of reset # is deep sleep, call the machine.reset_cause() function and test for machine.DEEPSLEEP_RESET import pyb, machine, sensor # Create and init RTC object. rtc = pyb.RTC() # (year, month, day[, hour[, minute[, second[, microsecond[, tzinfo]]]]]) rtc.datetime((2014, 5, 1, 4, 13, 0, 0, 0)) # Print RTC info. print(rtc.datetime()) sensor.reset() # Optionally bypass the regulator on OV7725 # for the lowest possible power consumption. if (sensor.get_id() == sensor.OV7725): # Bypass internal regulator sensor.__write_reg(0x4F, 0x18) # Enable sensor softsleep sensor.sleep(True) # Shutdown the sensor (pulls PWDN high). sensor.shutdown(True) # Enable RTC interrupts every 30 seconds. # Note the camera will RESET after wakeup from Deepsleep Mode. rtc.wakeup(30000) # Enter Deepsleep Mode. machine.deepsleep()
