==How to setup script??==1. Once you have logged into your Raspberry Pi from the command line, run the following commands sudo apt-get update sudo apt-get '''install python-smbus sudo apt-get install pigpio python-pigpio python3-pigpio'''

2. Download script and some sample code.Assuming your system is updated, add these packages: sudo apt-get install -y python-smbus python sudo apt-get install -y pigpio python-pigpio python3-pigpio git git clone https://github.com/geekworm-com/x735-v2.5.git 3. Setup script.

sudo chmod +x x735-v25*.sh sudo bash x735-v25install.sh printf "%s\n" echo "alias x735off='sudo x735softsd.sh'" >> ~/.bashrc 4. Reboot

5. '''Test safe shutdown'''

We can manually run the following commands: python ./x735'''read-fan-v25/pwm_fan_controlspeed.py'''Then the x735 fan will start working sudo ./read_fan_speed

But we hope that the script can be executed automatically when the Raspberry Pi board bootsAfter a reboot, we can use crontab command to achieve itrun ```sudo read_fan_speed. please refer py``` to get an update on the followingfan's current speed. Nice!

6. '''How to start PWM make the fan when pi 4 bootsscript run automatically after booting?'''

Add a In this way, this line at the end of command will be executed automatically when the file that reads like this:user logs in;

@reboot python3 /home/pi/x735-V22.5/pwm_fan_controlUse crontab to add a timed task. For details, please refer to [[How to add crontab job]].py
