# 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.

$ 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
