Micorpython DS1302 RTC Clock driver

This is a pure Micropython DS1302 RTC Clock driver. This is based on microbit code of microbit-lib https://github.com/shaoziyang/microbit-lib

This has been tested and working on ESP32 but should work with any micropython supported device.

Dirver documentation

(Adapted from https://github.com/shaoziyang/microbit-lib/blob/master/misc/DS1302/README.md)

DS1302 is real-time clock (RTC) with serial interface, 31 * 8 data ram.

API

• __init__(clk, dio, cs)
  set i/o pins

• start()
  start RTC.

• stop()
  stop/pause RTC

• date_time(DT = None)
  get / set DateTime. If no paramter given, it will return current datetime, otherwise it will set datatime.
  datatime format: [Year, month, day, weekday, hour, minute, second]

• year(year = None)
  get / set year.

• month(month = None)
  get / set month.

• day(day = None)
  get / set day.

• weekday(weekday = None)
  get / set month.

• hour(hour = None)
  get / set hour.

• minute(minute = None)
  get / set minute.

• second(second = None)
  get / set second.

• ram(reg, dat = None)
  get / set ram data (31 bytes).

example

from machine import Pin
import ds1302

ds = ds1302.DS1302(Pin(5),Pin(18),Pin(19))

ds.date_time() # returns the current datetime.
ds.date_time([2018, 3, 9, 4, 23, 0, 1, 0]) # set datetime.

ds.hour() # returns hour.
ds.second(10) # set second to 10.
