X708-Software
X708 script is same as X728, only X708 doesn't support RTC function.
The following test is base on '2020-02-13-raspbian-buster.img'
Python version: V2.7
1. Enable I2C funcion on Raspbian:
sudo raspi-config
Select 5 Interfacing Options and then P5 I2C - Enable/Disable automatic loading. A prompt will appear asking Would you like the ARM I2C interface to be enabled?, select "Yes"
Select "OK"
Select "Finish" to return to the command line and reboot your raspberry pi.
sudo reboot
2. Install necessary software (python and i2c tool library)
sudo apt-get install python-smbus sudo apt-get install i2c-tools
3. Download x728 setup scripts:
git clone https://github.com/geekworm-com/x728.git cd x728 sudo nano x728.sh #because X708 doesn't support RTC function, so we need to remove or comment out (add # at the beginning of the line) the following 4 lines #X728 RTC setting up #sudo sed -i '$ i rtc-ds1307' /etc/modules sudo sed -i '$ i echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_device' /etc/rc.local sudo sed -i '$ i hwclock -s' /etc/rc.local
4. Install script&reboot:
sudo bash x728.sh printf "%s\n" "alias x728off='sudo x728softsd.sh'" >> ~/.bashrc sudo reboot
6. How to reading battery voltage and percentage, this is the sample code, you can modify it by your request.
sudo python x728bat.py
7. Power off command on Raspbian from software
x728off
8. Testing AC power off/loss or power adapter failure detection (need to shor the 'PLD' pin)
sudo python x728pld.py
Return to X708
