X735-script
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.
This guideline is similar to XScript only because the hardware uses a different GPIO.
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
.
OS that has been tested
- Raspbian
- DietPi
- Manjaro
- Ubuntu
- myNode
- Umbrel
- Volumio
- RetroPie
- Twister
Preconfigured config.txt
To install pwm fan, first add dtoverlay=pwm-2chan,pin2=13,func2=4
to /boot/config.txt
under [all] or the end of file and reboot
:
sudo nano /boot/config.txt
Or (it's /boot/firmware/config.txt
if you are using ubuntu os
)
sudo nano /boot/firmware/config.txt
Save & exit.
sudo reboot
Clone the script
git clone https://github.com/geekworm-com/x735-script cd x735-script chmod +x *.sh
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.
sudo cp -f ./x735-fan.sh /usr/local/bin/ sudo cp -f ./x735-fan.service /lib/systemd/system sudo systemctl daemon-reload sudo systemctl enable x735-fan sudo systemctl start x735-fan
Then the pwm fan starts running.
Create the x735-pwr service
x735-pwr service will be responsible for power management and hardware safe shutdown.
sudo cp -f ./x735-pwr.sh /usr/local/bin/ sudo cp -f x735-pwr.service /lib/systemd/system sudo systemctl daemon-reload sudo systemctl enable x735-pwr sudo systemctl start x735-pwr
Prepair software shutdown script
sudo cp -f ./x735-softsd.sh /usr/local/bin/
Create a alias x735off
command to execute the software shutdown
echo "alias x735off='sudo /usr/local/bin/x735-softsd.sh'" >> ~/.bashrc source ~/.bashrc
Then you can run x735off
to execute software shutdown.
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
Other
pwm_fan_control.py
is no longer used, and are reserved here for research and use by python lovers only.
