<big>Although this installation tutorial is still available, but we strongly recommend that you use [[X729-script]] new tutorial, and we no longer maintain this page.</big> ==Setup script==The following test is base on * [https://downloads.raspberrypi.org/raspios_arm64/images/raspios_arm64-2023-05-03/2023-05-03-raspios-bullseye-arm64.img.xz 2023-05-03-raspios-bullseye-arm64.img.xz]* [https://www.raspberrypi.com/software/operating-systems/ 2022-09-22-raspios-bullseye-armhf.img.xz]* [https://www.raspberrypi.com/software/operating-systems/ 2022-09-22-raspios-buster-armhf.img.xz] PS: To buster version, the default user name is 'pi, but bullseye version, you need to manually create a new user. In our example script, the new user name we created is 'pi'. If you create your own user name, you need to modify the corresponding user name directory in the script. For Example: You may need to change '/home/pi/' => '/home/XX/', 'XX' is user name you created.

6.2 Run the commands to disable the "fake hwclock" which interferes with the 'real' hwclock

 6.3 Run the command and comment out these five lines: sudo nano /lib/udev/hwclock-set

6.5) 4 Reboot the Raspberry Pi pi@raspberrypi ~ $ sudo reboot

(6.6) 5 Run the command to verify the time is correct. Plug in Ethernet or WiFi to let the Pi sync the right time from the Internet pi@raspberrypi ~ $ date

(6.7) 6 Run the command to write the time pi@raspberrypi ~ $ sudo hwclock -w

(6.8) 7 Run the command to read the time pi@raspberrypi ~ $ sudo hwclock -r

Once the time is set, make sure the batteries are inserted so that the time is saved. You only have to set the time once. That's it! Next time you boot the time will automatically be synced from the [[X729]]. #If you need to set the system time for any reason you can use the following command : date -s "5 MAR 2019 13:00:00"  #Write the system date and time to the RTC module after your correct the system date and time : sudo hwclock -w

#Read ===7. How to enable automatic shutdown when low voltage===7.1 Run the date command to read battery voltage and time back from the RTC modulepercentage pi@raspberrypi: ~/x729 $ sudo hwclock -rpython3 bat.py

For the x728 old shell scriptSave and exit. In nano, you also run this command to remove itdo that by hitting CTRL + X, then re-install the x728 scriptanswering Y and hitting Enter when prompted.
