New page

{{GD Template Impl}}
<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-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.

Python version is 3;

==='''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 update
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-pigpio python3-pigpio

2.1 Once you have logged into your Raspberry Pi from the command line, run the command to see all the connected devices
<PRE>
pi@raspberrypi:~ $ sudo i2cdetect -y 1
0 1 2 3 4 5 6 7 8 9 a b c d e f

</PRE>
Explaination:
<PRE>
#36 - the address of the battery fuel gauging chip
#3c - address of oled display，This value only exists when the oled is inserted，check if the OLED is inserted in the correct direction if you don't found the above i2c port
#40 - TI INA219 12-bit current/voltage/power monitor
#68 - the address of the RTC chip
</PRE>

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:
cd ~
git clone https://github.com/geekworm-com/x729

3.2. Install script&reboot:
cd x729
chmod +x *.sh
sudo bash pwr.sh

#Setting up the command to turn off X729 from software
printf "%s\n" "alias x729off='sudo x729softsd.sh'" >> ~/.bashrc

#Reboot the Raspberry Pi or long press on-board button switch to turn off
sudo reboot now
3.3 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:
@reboot python3 /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'''===

5.1 Test AC Power loss or power adapter failure detection (PLD)

Run the script test the PLD function
sudo python3 pld.py
[[File:X729-8.png|none]]

5.2 Test Auto shutdown when AC power loss or power adapter failure

Run the script and then remove your power adapter
pi@raspberrypi:~/x729 $ sudo python3 plsd.py
Safe shutdown will be implemented in 5 seconds.

5.3 Test the buzzer alarm when AC power loss or power adapter failure

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

==='''6. Set and Read the RTC time'''===

6.1 Run the following command on your Raspberry PI to begin editing the /boot/config.txt file.
sudo nano /boot/config.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.png|none]]

6.4 Reboot the Raspberry Pi
pi@raspberrypi ~ $ sudo reboot

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

6.6 Run the command to write the time
pi@raspberrypi ~ $ sudo hwclock -w

6.7 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]].

===7. How to enable automatic shutdown when low voltage===
7.1 Run the command to read battery voltage and percentage
pi@raspberrypi:~/x729 $ sudo python3 bat.py

7.2 Change the battery low voltage to 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.

7.3 Optional - if you want to run Python Script automatically on Bootup then run the command
pi@raspberrypi:~/x729 $ sudo crontab -e

7.4 Add a line at the end of the file that reads like this:
@reboot python3 /home/pi/x729/bat.py
[[File:X729-4.png|none]]

Save and exit. In nano, you do that by hitting CTRL + X, answering Y and hitting Enter when prompted.

===8. How to enable OLED display===
Refer to [[How to enable OLED display]]

==Uninstall cript==
uninsatll x729 shell script, run the following command:
sudo ./uninstall_x729.sh

==Other resource==
