 <span class="tb_red"><big>This tutorial is deprecated, see [[X735-script]]</big></span>  ==Overview==This guide is only for also applies to [[X735 ]] V3.0 / V2.5 shield based on RASPBIANshield； ==For Raspbian / Raspbian Lite / RetroPie / Twister OS v2.0.2==Test '2022-04-04-raspios-bullseye-armhf-lite. (Not tested img' on Ubuntu, openmediavault, retropie or other third party OS like Manjaro.)May 6th 2022;

Assuming your system is updated, add these packages: sudo apt-get update sudo apt-get upgrade  sudo apt-get install python-smbusy git sudo apt-get install -y pigpio pythonpython3-pigpio sudo apt-get install -y python3-smbus python3-pigpiorpi.gpio

sudo python3 read_fan_speed./pyor sudo python read_fan_speed.py

After a reboot, we can run ```sudo python read_fan_speed.py``` to get an update on the fan's current speed. Nice!

There are two ways to achieve it;it： 1. Put the following command line in the /etc/rc.local file: （'''Default''') vi /etc/rc.local <source lang='shell' line highlight="21">#!/bin/sh -e## rc.local## This script is executed at the end of each multiuser runlevel.# Make sure that the script will "exit 0" on success or any other# value on error.## In order to enable or disable this script just change the execution# bits.## By default this script does nothing. # Print the IP address_IP=$(hostname -I) || trueif [ "$_IP" ]; then printf "My IP address is %s\n" "$_IP"fi /etc/x735pwr.sh &python /home/pi/x735-v2.5/pwm_fan_control.py&exit 0</source> NOTE: * The install.sh script will make sure this command line is put into the rc.local file, you don't need to do anything.* Please change 'python' to 'python3' if you are using python3.* Please make sure the file path of pwm_fan_control.py is correct.  2. Use crontab to add a timed task.
