The following test is base on '2020-02-13-raspbian-buster.img'
Python version: V2.7
1. Enable I2C funcion on Raspbian:
reter to How to enable I2C
2. Login via teminal window, then update & upgrade & install necessary software (python and i2c tool library)
sudo apt-get update sudo apt-get upgrade sudo apt-get -y install i2c-tools python3-smbus python-smbus
2.1 Once you have logged into your Raspberry Pi from the command line, run the command to see all the connected devices
sudo i2cdetect -y 1 #36 - the address of the battery fuel gauging chip #68 - the address of the RTC chip #Different x728 versions may have different values
3. Download x728 setup scripts:
cd ~ git clone https://github.com/geekworm-com/x728 cd x728 chmod +x *.sh
4. Install script&reboot:
Firstly please select your x728 version
sudo bash x728-v2.1.sh #New add buzzer support
or
sudo bash x728-v2.0.sh
or
sudo bash x728-v1.0.sh
then
sudo reboot
You can get the following python file in /home/pi/ fold:
x728bat.py # Reading battery voltage x728pld.py # Testing AC power off/loss or power adapter failure detection, added buzzer function on v2.1
5. Set and Read the RTC time
#If you need to set the system time for any reason you can use the following command : date -s "5 MAR 2019 13:00:00"
#Write the system date and time to the RTC module after your correct the system date and time : sudo hwclock -w
#Read the date and time back from the RTC module: sudo hwclock -r
6. How to reading battery voltage and percentage, this is the sample code, you can modify it by your request.
sudo python /home/pi/x728bat.py
User Guide: https://github.com/geekworm-com/x728 to know more details;
But we hope that the script can be executed automatically when the Raspberry Pi board boots, we can use crontab system command to achieve it. please refer to the following:
pi@raspberrypi ~ $ `sudo crontab -e`
Choose "`1`" then press Enter
Add a line at the end of the file that reads like this:
`@reboot python /home/pi/x728bat.py`
7. Power off command on Raspbian from software
x728off
- x728off is safe shutdown command
- press on-board blue button 1-2 seconds to reboot
- press on-board blue button 3 seconds to safe shutdown,
- press on-board blue button 7-8 seconds to force shutdown.
8. Testing AC power off/loss or power adapter failure detection (need to short the 'PLD' pin on v1.x), also test the buzzer function on v2.1
sudo python x728pld.py
uninstall x728 script
uninsatll x728 shell script, run the following command:
sudo ./uninstall_x728.sh
For the x728 old shell script, you also run this command to remove it, then re-install the x728 script.
FAQ
Q: We want to automatically shut down when the battery voltage is lower than a certain specified value, is it possible?
A: Please run the followng command to achieve this function.(Note: 3V is default shut down voltage value )
