My Test

This is script installation tutorial for NASPi, NASPi Gemini 2.5, NASPi CM4-M2 and NASPi CM4-2.5

This script also works on bookworm OS, and test it on Jan. 9th 2024.

The original key pwm fan control script is from pimlie/geekworm-x-c1, pimlie implements the pwm fan shell script, which does not depend on third-party python libraries at all. Thanks to pimlie.

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 Raspberry Pi OS.

After your system boots, then you need to open Terminal prpgram, then type the following command to complete the installation of the script

[NOTE]

If you are a new user, please ignore this NOTE

If you are using the latest Raspberry Pi OS bookworm version or have updated the OS kernel to the latest version 6.6, then you get the following error after running the xoff command:

/usr/local/bin/x-c1-softsd.sh: line 5: echo: writing error: Invalid argument
/usr/local/bin/x-c1-softsd.sh: line 6: /sys/class/gpio/gpio27/direction: No such file or directory
/usr/local/bin/x-c1-softsd.sh: line 7: /sys/class/gpio/gpio27/value: No such file or directory
Your device will shutting down in 4 seconds...
/usr/local/bin/x-c1-softsd.sh: line 19: /sys/class/gpio/gpio27/value: No such file or directory

The cause of this error is due to a kernel update, please perform the following update to solve the issue;

1. First go back to the directory where you installed xscript and you will see the xscript folder.

2. Then run the following command:

cd xscript
rm x-c1-softsd.sh x-c1-pwr.sh -f
git pull origin
chmod +x *.sh
sudo cp -f . /x-c1-softsd.sh /usr/local/bin/
sudo cp -f . /x-c1-pwr.sh /usr/local/bin/
sudo reboot

OS that has been tested

• Raspbian
• DietPi
• Manjaro
• Ubuntu
• myNode
• Umbrel
• Volumio
• RetroPie
• Twister

Note: Not tested with Home Assistant, for some reason, we are not able to upgrade and use the Home Assistant to test, please pay attention to check if there is any update in the future.(If you have successfully tested Home Assistant, welcome to share your experience via email at: support@geekworm.com)

Preconfigured config.txt

To install pwm fan, first add dtoverlay=pwm-2chan to /boot/firmware/config.txt under [all] or the end of file and reboot:

sudo nano /boot/firmware/config.txt

Save & exit.

sudo reboot

Clone the script

git clone https://github.com/geekworm-com/xscript

cd xscript
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

Create the x-c1-fan service

Note: If your device does not support pwm fans or you are not using pwm, you can skip this step

sudo cp -f ./x-c1-fan.sh                /usr/local/bin/
sudo cp -f ./x-c1-fan.service           /lib/systemd/system
sudo systemctl daemon-reload
sudo systemctl enable x-c1-fan
sudo systemctl start x-c1-fan

Then the pwm fan starts running.

Create the x-c1-pwr service

sudo cp -f ./x-c1-pwr.sh                /usr/local/bin/
sudo cp -f x-c1-pwr.service             /lib/systemd/system
sudo systemctl daemon-reload
sudo systemctl enable x-c1-pwr
sudo systemctl start x-c1-pwr

Prepair software shutdown script

sudo cp -f ./x-c1-softsd.sh             /usr/local/bin/

Create a alias xoff command to execute the software shutdown

echo "alias xoff='sudo /usr/local/bin/x-c1-softsd.sh'" >>   ~/.bashrc
source ~/.bashrc

Then you can run xoff to execute software shutdown.

Test safe shutdown

Software safe shutdown command:

xoff

DON'T run the 'shutdown' linux command to shut down, otherwise the power of 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 1-2 seconds to reboot
• press button switch 3 seconds to safe shutdown,
• press 7-8 seconds to force shutdown.

Sample

1. The code for fan speed control is now in the x-c1-fan.sh file.
2. fan-rpi.py and fan-pigpio.py are no longer used, and are reserved here for research and use by python lovers only.

Uninstall

Uninstall x-c1-fan.service:

sudo systemctl stop x-c1-fan
sudo systemctl disable x-c1-fan

Uninstall x-c1-pwr.service:

sudo systemctl stop x-c1-pwr
sudo systemctl disable x-c1-pwr

Remove the xoff allias on .bashrc file

sudo sed -i '/xoff/d' ~/.bashrc
source ~/.bashrc
