1. Enable I2C funcion on Raspbian;
sudo apt-get update
#sudo apt-get install python-smbus
sudo apt-get install python3-smbuspython3-rpi.gpio
sudo apt-get install i2c-tools
3. Check if the i2c of the X708 is connected correctly sudo i2cdetect -y 1
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --
If you can't find i2c address 36, it means the X708 is not connected properly, or your raspberry pi board is broken. 3.1. Download x708 setup scripts: cd ~ git clone https://github.com/geekworm-com/x708x708v2This command will download the script installation file for X708 4. Install the script for power management 4.git1 Enters the corresponding operating system scripts folder (raspberry-pi-os) cd x708~/x708v2/raspberry-pi-os/ 4.2 Execute the installation script. chmod +x installsudo bash pwr.sh
This command will generate 2 power management script files as follows:
*/etc/x708pwr.sh
*/usr/local/bin/x708softsd.sh
4. Install script&reboot: sudo bash install.sh3 Create an alias x708off so that we can perform software shutdown from the command line, you can also change x708off to any name you like printf "%s\n" "alias x708off='sudo x708softsd.sh'" >> ~/.bashrc
sudo reboot
Or force press the button of x708 for 8 seconds to shut down and then restart
4.5 Press on-board button or external switch to test hardware safe shutdown
Press the switch for about 3 seconds until the power indicator flashes to execute hardware safe shutdown.
'''[NOTE]''':
* After shutdown, press the onboard switch or external switch to turn on.
* If your test fails, it means that your installation failed, or the software environment is incorrect, please check whether you have installed the corresponding software package.
5. How to reading battery voltage and percentage, this is the sample code, you can modify it by your request.
cd ~/x708v2/raspberry-pi-os/
sudo python3 bat.py
<pre>
******************
Voltage: 4.18V
Battery: 100%
Battery FULL
******************
Voltage: 4.17V
Battery: 100%
Battery FULL
******************
Voltage: 4.18V
Battery: 100%

******************

</pre>
* In generally, you need to let the X708 fully charge and discharge several times before you can get more accurate voltage and power values.
* This script can also perform safe shutdown at specified voltage threshold (default voltage threshold is 3.00vdc), you can also modify this voltage threshold, '''but the voltage threshold range must be 2.5~4.1vdc'''.
6. Testing AC power off/loss or power adapter failure detection (PLD function)
cd ~/x708v2/raspberry-pi-os/
sudo python3 pld.py
<pre>
1.Make sure your power adapter is connected
2.Disconnect and then connect the power adapter again to test
3.When power adapter disconnected, you will see: AC Power Loss or Power Adapter Failure
4.When power adapter reconnected, you will see: AC Power OK, Power Adapter OK
Testing Started---AC Power Loss OR Power Adapter Failure---
---AC Power OK,Power Adapter OK---
---AC Power Loss OR Power Adapter Failure---
---AC Power OK,Power Adapter OK---
</pre>
7. Test Auto shutdown when AC power loss or power adapter failure
cd ~/x708v2/raspberry-pi-os/
sudo python3 plsd.py
Testing Started---AC Power Loss OR Power Adapter Failure---
Shutdown in 5 seconds
Connection closing...Socket close.
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. 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 fan running at high speed or low speed via modify the CPU temperature threshold in fan.py script file (yellow highlight line)
<syntaxhighlight lang="python" line highlight="9-11">
#!/usr/bin/env python3
import subprocess
import 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. DON'T change it!
'''[PS]'''
* If you can't understand, please ignore this step. Because the X708 fan 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-pi-os/fan.py', 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]]
