Overview

This is script installation tutorial for X735 v2.5 & v3.0, it will replace X735 Software installation tutorial, although X735 Software installation tutorial is still available, but we strongly recommend that you use this script tutorial, which simplifies the installation process and reduces dependencies on third-party python libraries.

The core shell script of X735-script comes from 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 OS. You need to perform the following operations in Terminal.

[NOTE]

If you are using an ubuntu system, DO NOT use version ubuntu 23.04, otherwise you will get an error similar to the following when you run x735off:

/usr/local/bin/x735-softsd.sh: line 5: /sys/class/gpio/export: No such file or directory
/usr/local/bin/x735-softsd.sh: line 6: /sys/class/gpio/gpio20/direction: No such file or directory
/usr/local/bin/x735-softsd.sh: line 7: /sys/class/gpio/gpio20/value: No such file or directory
Your device will shutting down in 4 seconds...
/usr/local/bin/x735-softsd.sh: line 19: /sys/class/gpio/gpio20/value: No such file or directory

Resolved! Please delete the old installation folder and re-install it by the following guide.

OS that has been tested

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

Install

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

Clone the script

Clone pruduct software script

git clone https://github.com/geekworm-com/x735-script
cd x735-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

Create the x735-fan service

x735-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.

Run the following command to install fan service script;

./install-fan-service.sh

Then the pwm fan starts running.

Create the x735-pwr service

If you are using ubuntu verson 23.04 or more high version, please run the following command:

./install-pwr-service-ubuntu.sh

OR run the following command to install power management script;

./install-pwr-service.sh

Prepair software shutdown script

If you are using ubuntu verson 23.04 or more high version, please run the following command:

./install-sss-ubuntu.sh

OR, Run the following command to install software shutdown script (sss),

./install-sss.sh

After the installation is complete, an x735xoff command will be created to shut down the software.Then you can run x735xoff to execute software shutdown.

Uninstall

Run the following command to uninstall all.

./uninstall.sh

Test safe shutdown

Software safe shutdown command:

x735off

DON'T run the 'shutdown' linux command to shut down, otherwise the power of x735 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.

Read fan speed

read_fan_speed.py is a sample python file on how to read the speed of the pwm fan. Run the following command to get the speed of the fan:

cd ~x735-script
sudo python3 read_fan_speed.py

This `read_fan_speed.py` python file 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
