<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.

==='''1. Enable I2C funcion on Raspbian:'''===  Please reter to [[How to enable I2C]] ==='''2. Check & review I2C address'''===

2. 1 Login via teminal window, then update & upgrade & install necessary software (python and i2c tool library)

sudo apt-get -y upgrade sudo apt-get -y install i2c-tools python3-smbus python3-rpi.gpio sudo apt-get -y install python3-pip python3-pil #sudo apt-get -y install pigpio python-smbuspigpio python3-pigpio

#3c - address of oled display，This value only exists when the oled is inserted，check if the OLED displayis inserted in the correct direction if you don't found the above i2c port

PS： Please check if the OLED is inserted in the correct direction if you don't found the above i2c port ==='''3. Setting up the power management script'''=== 3.1 Download x729 setup scripts:

43.2. Install script&reboot: cd x729 chmod +x *.sh

#Setting up the command to turn off X729 from software

#Reboot the Raspberry Pior long press on-board button switch to turn off sudo reboot now3.3 Powering off the Raspberry Pi from software x729off * x729off is safe shutdown command* press on-board blue button 1-2 seconds to reboot* press on-board blue button 3 seconds to safe shutdown,* press on-board blue button 7-8 seconds to force shutdown. ==='''4. Setting up the PWM cooling fan'''=== cd ~ cd x729 python3 pwm_fan_control.py 4.1 Run the script at Raspberry Pi boot  sudo crontab -e [[File:Crontab-step1.png|none]] Choose "1" then press Enter 4.2 Add a line at the end of the file that reads like this: @rebootpython3 /home/pi/x729/pwm_fan_control.py [[File:X729-2.png|none]] 4.3 Save and exit. In nano, you do that by hitting CTRL + X, answering Y and hitting Enter when prompted. 4.4 Run below script and you will get RPM value every second: cd ~ cd x729 python3 read_fan_speed.py  ==='''5. Test PLD/PLSD/buzzer function'''=== 

5. Set and Read the RTC time #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"1 Test AC Power loss or power adapter failure detection (PLD)

#Write Run the system date and time to script test the RTC module after your correct the system date and time : PLD function sudo hwclock python3 pld.py[[File:X729-w8.png|none]]

6. How to reading battery voltage Run the script and percentage, this is the sample code, you can modify it by then remove your request.power adapter sudo python /home/pi@raspberrypi:~/x728batx729 $ sudo python3 plsd.py[[File:X728-bat-2Safe shutdown will be implemented in 5 seconds.jpg]]

But we hope that 5.3 Test the script can be executed automatically buzzer alarm when the Raspberry Pi board boots, we can use crontab system command to achieve it. Refer to [[How to add crontab job]] AC power loss or refer to the following:power adapter failure

Run the script and unplug your power adapter from the UPS. pi@raspberrypi :~ /x729 $ `sudo crontab -e`python3 buzzer.py Once power adapter is removed then the buzzer will generate a beep sound continuously.

Add a line at ==='''6. Set and Read the end of the file that reads like this:RTC time'''===

6.1 Run the following command on your Raspberry PI to begin editing the /boot/config.txt file. `@reboot python /homesudo nano /piboot/x728batconfig.py`txt

add one of the following lines to the bottom of the file, dtoverlay=i2c-rtc,ds1307 [[File:X729-5.png|none]] Save and exit. In nano, you do that by hitting CTRL + X, answering Y and hitting Enter when prompted. 6.2 Run the commands to disable the "fake hwclock" which interferes with the 'real' hwclock pi@raspberrypi ~ $ sudo apt-get -y remove fake-hwclock pi@raspberrypi ~ $ sudo update-rc.d -f fake-hwclock remove pi@raspberrypi ~ $ sudo systemctl disable fake-hwclock[[File:X729-6.png|none]] 6.3 Run the command and comment out these five lines: sudo nano /lib/udev/hwclock-set[[File:X729-7. Power off png|none]] 6.4 Reboot the Raspberry Pi pi@raspberrypi ~ $ sudo reboot 6.5 Run the command on Raspbian to verify the time is correct. Plug in Ethernet or WiFi to let the Pi sync the right time from softwarethe Internet x728offpi@raspberrypi ~ $ date * x728off is safe shutdown 6.6 Run the commandto write the time* press on pi@raspberrypi ~ $ sudo hwclock -board blue button 1w 6.7 Run the command to read the time pi@raspberrypi ~ $ sudo hwclock -2 seconds r Once the time is set, make sure the batteries are inserted so that the time is saved. You only have to rebootset the time once. That's it! Next time you boot the time will automatically be synced from the [[X729]]. * press on-board blue button 3 seconds ===7. How to safe enable automatic shutdown,when low voltage===7.1 Run the command to read battery voltage and percentage pi@raspberrypi:~/x729 $ sudo python3 bat.py  * press on-board blue button 7-8 seconds .2 Change the battery low voltage to force implement safe shutdown. default is less than 3.00Vdc. pi@raspberrypi ~ $ sudo nano bat.py [[File:X729-3.png|none]]Note: the voltage range must be 2.5~4.1vdc.

[[File7.3 Optional - if you want to run Python Script automatically on Bootup then run the command pi@raspberrypi:X728-pld~/x729 $ sudo crontab -2.jpg]]e

==uninstall x728 script==uninsatll x728 shell script, run 7.4 Add a line at the end of the following commandfile that reads like this: sudo @reboot python3 /home/pi/x729/bat./uninstall_x728py[[File:X729-4.shpng|none]]

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.

==FAQ=8. How to enable OLED display===Q: We want Refer to [[How to automatically shut down when the battery voltage is lower than a certain specified value, is it possible?enable OLED display]]

A: Please ==Uninstall cript==uninsatll x729 shell script, run the followng following command to achieve this function.(Note: 3V is default shut down voltage value ) python3 /home/pi/x728sudo ./x728v2-asduninstall_x729.py &sh
