Overview
[NOTE]: X729 supports Raspberry Pi 5 hardware also
This is script installation tutorial for X729 shield, it will replace X729 Software installation tutorial, and simplifies the installation process and reduces dependencies on third-party python libraries.
Now we think you have successfully flashed the OS Image into Micro SD and and power on the device, and you have also completed the operations such as creating new user required in some OS. You need to perform the following operations in Terminal.
[Update]:
1. Use gpiod instead of obsolete interface
2. The script now supports the Raspberry Pi OS BOOKWORM version. You just need to uninstall the original script and reinstall it. Please refer to the following:
OPen ternimal window, then run the following command:
mv x729-script x729-script-old git clone https://github.com/geekworm-com/x729-script cd x729-script chmod +x *.sh ./uninstall.sh
Then just follow the installation process below.
3. If you are using it on a Raspberry Pi 5 hardware, make sure to update the 6.6.22 or more high kernel version (uname -a to check kernel version)
sudo apt update sudo apt full-upgrade sudo rpi-update
OS that has been tested
- Raspbian
- DietPi
- Manjaro
- Ubuntu
- myNode
- Umbrel
- Volumio
- RetroPie
- Twister
Install
Please follow the steps below:
Enable I2C
Reter to How to enable I2C
NOTE: sample/bat.py will run with error if you don't enable I2C.
Check & review I2C address:
pi@raspberrypi:~ $ sudo i2cdetect -y 1
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- -- --

Explaination:
#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
Preconfigured config.txt
To install pwm fan, first add dtoverlay=pwm-2chan,pin2=13,func2=4 to /boot/firmware/config.txt under [all] or the end of file and reboot:
sudo nano /boot/firmware/config.txt
Save & exit.
sudo reboot
Install gpiod package
sudo apt install -y gpiod
Clone the script
git clone https://github.com/geekworm-com/x729-script cd x729-script chmod +x *.sh
PS: For some OS such as Raspberry Pi OS Lite, the git tool is not installed by default, if you get an error like error: -bash: git: command not found, please run the following command to install the git tool.
sudo apt install -y git
Configuring Different gpipchip number and pwmchip number for Raspberry Pi 5 hardware
If you are NOT using Raspberry 5 hardware, skip this step,or run the following command to set differnt chip and pwm number.
PS: Since 2024-09-02, Raspberry Pi has finally unified the gpipchip to 0 on all Raspberry Pis(Pi, 0, 1, 2, 3, 4, 5). Previously, the gpiochip on the Raspberry Pi 5 was 4.
So we comment out the following command line.
#sed -i 's/xPWR.sh 0 5 12/xPWR.sh 4 5 12/g' x729-pwr.service
PS: But on the Raspberry Pi 5 the pwmchip is still 2, not 0 as used on the Pi 0/1/2/3/4, so you still run the following command if you work on RPi 5 hardware.
sed -i 's/pwmchip0/pwmchip2/g' x729-fan.sh
Create the x729-fan service
x729-fan service is for pwm fan, the pwm fan will automatically adjust the runing speed according to the temperature of the cpu after the service is started.
sudo cp -f ./x729-fan.sh /usr/local/bin/ sudo cp -f ./x729-fan.service /lib/systemd/system sudo systemctl daemon-reload sudo systemctl enable x729-fan sudo systemctl start x729-fan
Then the pwm fan starts running.
Create the x729-pwr service
x729-pwr service will be responsible for power management and hardware safe shutdown.
sudo cp -f ./xPWR.sh /usr/local/bin/ sudo cp -f x729-pwr.service /lib/systemd/system sudo systemctl daemon-reload sudo systemctl enable x729-pwr sudo systemctl start x729-pwr
Now, if you press and hold the onboard switch for 3 seconds, then the blue LED will flash slowly and the shutdown is going then all LEDs will be off until the device is completely powered off.
Prepair software shutdown script
sudo cp -f ./xSoft.sh /usr/local/bin/
Then create a x729off alias command to execture safe shutdown command.
echo "alias x729off='sudo /usr/local/bin/xSoft.sh 0 26'" >> ~/.bashrc
Run the following command to make the alias x729off effective
source ~/.bashrc
Then you can run x729off to execute software shutdown as follows
x729off
DON'T run the 'shutdown' linux command to shut down, otherwise the power of x729 shield will not be shut down.
Uninstall
./uninstall.sh
Test safe shutdown
Software safe shutdown command:
x729off
DON'T run the 'shutdown' linux command to shut down, otherwise the power of x729 shield will not be shut down.
Hardware safe shutdown operation:
You can verify the safety switch through the onboard switch, press and hold the switch for 3 seconds, then the blue LED will flash slowly and the shutdown is going then all LEDs will be off until the device is completely powered off.
- press on-board button switch
1-2seconds to reboot - press button switch
3seconds to safe shutdown, - press
7-8seconds to force shutdown.
Sample Files
The example programs are only suitable for advanced players, and you can construct your own usage scenarios according to the example programs.
[PS]
The old example code uses the RPi.GPIO library, which is currently not supported in kernel 6.6.x, so you may encounter an error when running the following code
sudo python3 sample/plsd.py
Note that you need to provide a different gpiochip number on Pi 0,1,2,3,4 (0) and Pi 5 (4).
For other example programs that use the RPi.GPIO library, it is recommended that you change to the libgpiod version if it runs incorrectly, and we also provide ONLY ONE example using the libgpiod library (plsd-gpiod.py), which you can run as follows:
sudo python3 sample/plsd-gpiod.py
For other example programs that use the RPi.GPIO library, it is recommended that you change to the libgpiod version if it runs incorrectly.
Each example program demonstrates a different function:
read_fan_speed.py: Read the pwm fan running speed;
cd ~x729-script sudo python3 sample/read_fan_speed.py
pld.py: AC Power supply loss dection script;
cd ~x729-script sudo python3 sample/pld.py
plsd.py: Auto shutdown when AC power loss or power adapter failure script;(Added auto shuntdown function base pld.py)
cd ~x729-script sudo python3 sample/plsd.py
buzzer.py: demonstrates how the buzzer will sound when power supply is lost, which is very important in some usage scenarios.
cd ~x729-script sudo python3 sample/buzzer.py
PS:
1. The above sample python file maybe depends on the third-party python library `Rpi.GPIO`. In the official Raspberry Pi OS and most third-party OS, this library is installed by default. If you run this file and get some errors, try to run the following command to install the Rpi.GPIOy library.
sudo apt-get install -y python3-smbus python3-rpi.gpio
Or you can refer to How to Install RPi.GPIO Python Library
2. The sample program is only to demonstrate how to use the advanced functions of the shield, we do not provide the development function of the sample program.
