# before installation
# turn on the i2c interface on raspbian.
# make sure there's no other phat using address 0x32 or 0x75
# make sure your python version is 3.6
# check if device 0x32 and 0x75 work.
# If you can't find them or find some meaningless random code, please reattach the battery module and try again.
i2cdetect -y 1

Start the core with Web UI:
$ python3 core/PiSugarCore.py
# core program will host an http server at port 8000
# please visit http://<ip of your pi>:8000
# core program will also create a unix domain socket file: /tmp/pisugar.sock
# use following commands to get / set data from the battery
# get model (pisugar model)
# get battery (battery level percent)
# get battery_v (lithium battery votage)
# get battery_i (lithium battery current)
# get battery_charging (charging status)
# get rtc_time (rtc time string)
# get rtc_time_list (rtc time in python list)
# get rtc_alarm_flag (rtc alarm flag)
# get safe_shutdown_level
# get alarm type (1: daily alarm, 0: off)
# get alarm time (alarm timestamp)
# get alarm type (alarm week repeat)
# get button enable <type> (type: single/double/long)
# get button shell <type> (type: single/double/long)
# rtc_clean_flag (clean alarm flag)
# rtc_pi2rtc (sync time from Pi to rtc)
# rtc_alarm_set (set auto wake up alarm)
# rtc_alarm_disable (disable wake up alarm)
# rtc_test_wake (test wake in 1min30sec)
# set_button_enable (argv1: single/double/long argv2: 1/0)
# set_button_shell (argv1: single/double/long argv2: shell script to execute)
# set_safe_shutdown_level (e.g. -1 / 3 / 5)
# e.g. get battery level precentage
$ echo get battery | nc -U /tmp/pisugar.sock
63.15938281249997
# e.g. set auto wake up alarm on 15:39:00 repeat on Sun, Mon, Tue, Wed, Sat
$ echo rtc_alarm_set 0,39,15,0,0,0,0 0b1001111 | nc -U /tmp/pisugar.sock
Done.
