Shutdown in 5 seconds
In fact, you can refer to this example code to implement your own shutdown logic. . . This requires you to have some python programming foundation.
8. Automatically Advanced use of speed regulation for non-pwm fans The X708 hardware supports two fan speeds: low speed (default) and high speed; if you want the fan to run at high speed, you need to run the fan.py script. cd ~/x708v2/raspberry-pi-os/ python3 fan.py fan.py provides a method that can switch the fan speed. It should be noted that the x708 does not use a PWM fan, it only supports two speed modes (low speed and high speed). In the fan.py file, the speed mode of the fan is controlled by reading the temperature of the CPU in real time. You need to read the fan.py code to understand more logic. You can control the cooling Fan fan running at high speed or low speed via modify the CPU temperature threshold in fan.py script file (yellow highlight line)<span stylesyntaxhighlight lang="color:#23AC38python">pi@raspberrypi</span>:<span styleline highlight="color:#50BEDB9-11">~ $<#!/span> cd ~usr/x708v2/raspberry-pi-osbin/env python3 import subprocessimport time from gpiozero import OutputDevice ON_THRESHOLD = 55 # (degrees Celsius) Fan running at high speed at this temperature.OFF_THRESHOLD = 50 # (degress Celsius) Fan running at low speed at this temperature.SLEEP_INTERVAL = 5 # (seconds) How often we check the core temperature.GPIO_PIN = 16 # Which GPIO pin you're using to control the fan.

'''[[File:PS]''' * If you can't understand, please ignore this step. Because the X708fan will run at low speed by default, this cooling capacity is sufficient.* If you have full control over the runing of the fan, you need to run 'python3 /home/pi/x708v2/raspberry-v2pi-os/fan.pngpy', and you need to create a crontab job also, and then put this run command ('@reboot python3 /home/XX/x708v2/raspberry-pi-os/fan.py 'XX' is your username, you need replace it with your username.') into the job, so that the command will run automatically when the device restarts. refer to [[X708-Software#FAQ]]
9. Uninstall

About '''AUTO ON''' After shutting down, you need to wait about 60 seconds until the battery capacity indicator of X708 goes out, otherwise the AUTO ON function may be invalid. Because the charge remaining in the power adapter may affect the AUTO ON function.

==FAQ==
Q1: Can't connect How to pigpio at localhost(8888)<pre>Can't connect to pigpio at localhost(8888)Did you start the pigpio daemonmake a script run automatically after boot? E.g. sudo pigpiod
Did you specify the correct Pi host/port in the environmentvariables PIGPIO_ADDR/PIGPIO_PORT?E.g. export PIGPIO_ADDR=soft, export PIGPIO_PORT=8888A: Refer to [[How to add crontab job]]
Did you specify the correct Pi host/port in thepigpio.pi() function? E.g. pigpio.pi('soft', 8888)%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%Traceback (most recent call last): File "/home/volumio/x-c1/fan.py", line 8, in <module> pwm.set_mode(servo, pigpio.OUTPUT) File "/usr/lib/python2.7/dist-packages/pigpio.py", line 1376, in set_mode return _u2i(_pigpio_command(self.sl, _PI_CMD_MODES, gpio, mode)) File "/usr/lib/python2.7/dist-packages/pigpio.py", line 1025, in _pigpio_command sl.s.send(struct.pack('IIII', cmd, p1, p2, 0))AttributeError: 'NoneType' object has no attribute 'send'</pre>A: If you find an error similar Return to the above, it is because pigpiod library is not started, we need to run pigpiod first, sudo pigpiod python 'your directory'/x-c1/fan.py &If 'sudo' command request a password, you can use the following command: echo 'your password' | sudo -S pigpiod python 'your directory'/x-c1/fan.py &You can put these two lines in the /etc/rc.local file so that it will run automatically after booting.
