==How to setup safe shutdown script??=='''install''' 1. Once you have logged into Assuming your Raspberry Pi from the command linesystem is updated, run the following commandsadd these packages: sudo apt-get updateinstall -y python-smbus python sudo apt-get install -y pigpio python-smbus pigpio python3-pigpio git git clone https://github.com/geekworm-com/x735-v2.5 cd x735-v2.5 sudo chmod +x *.sh sudo bash install.sh echo "alias x735off='sudo x735softsd.sh'" >> ~/.bashrc sudo aptreboot '''Test safe shutdown''' x735off* x735off is safe shutdown command, you can run this command to safe shutdown.* press button 1-get install i2c2 seconds to reboot* press button 3 seconds to safe shutdown,* press 7-tools 8 seconds to force shutdown. '''uninstall''' sudo apt./uninstall.sh '''read-fan-speed.py''' sudo ./read_fan_speed After a reboot, we can run ```sudo read_fan_speed.py``` to get install pigpio python-pigpio python3-pigpioan update on the fan's current speed. Nice! '''How to make the fan script run automatically after booting?'''

2There are two ways to achieve it;1. Download script and some sample codePut the following line at the end of .bashrc file: （Default) cd ~ git clone https://githubnano .com/geekworm-com/X735-V2bashrccopy the following line to .5bashrc file.git

3. Setup script. cd X735python /home/pi/x735-V2v2.5 sudo bash x735-v25.sh printf "%s\n" "alias x735off='sudo x735softsd.sh'" >> ~/pwm_fan_control.bashrcpy &

4NOTE: Maybe you need to modify the file path if you use other OS. Reboot sodu reboot

== About python sample code== read_fan_speed2.py This is only show how Use crontab to get the fan speed every secondadd a timed task. sudo python read_fan_speedFor details, please refer to [[How to add crontab job]].py

==For DietPi=='''install''' sudo apt-get install -y python-smbus python pwm_fan_controlsudo apt-get install -y pigpio python-pigpio python3-pigpio git git clone https://github.py com/geekworm-com/x735-v2.5 This is the phthon sample file to control fan speed by CPU temperaturecd x735-v2. you can refer to this sample or modify it by your request5 sudo chmod +x *. please contact us if you found some error for this filesh sudo bash install-dietpi.sh

You can use the echo "alias x735off='crontabsudo /usr/local/bin/x735softsd' system command " >> ~/.bashrc sudo reboot == For myNode OS and Umbrel ==About myNode, please refer to execute this python file http://www.mynodebtc.com/ About Umbrel, please refetrto https://getumbrel.com/ '''Install''' login to get mynode teminal via Putty or Xsheel tool, the function of speed adjustment according default user name is `admin`, password is `bolt`, then run the following command: Login to temperature changes.mynode teminal via Putty or Xsheel tool, the default user name is `umbrel`, default password is `moneyprintergobrrr`, then run the following command:
