ds.datetime() returns "TypeError: can't convert I2C to int"

[veethahavya-CU-cz]

Hi,

I wired up a tinyRTC onto I2C bus 1 on a Raspberry Pi Pico and tried running the example. But it resulted in an error:

MicroPython v1.22.2 on 2024-02-22; Raspberry Pi Pico with RP2040

>>> from machine import I2C, Pin
>>> i2c = I2C(1)
>>> i2c.scan()
[80, 104]
>>> import ds1307
>>> ds = ds1307.DS1307(i2c)
>>> ds.datetime()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/lib/ds1307.py", line 124, in datetime
TypeError: can't convert I2C to int

so, that would be:

...
124 |   buf = self._i2c.readfrom_mem(self._addr, DATETIME_REG, 7)
...

expanded:

...
    @property
    def datetime(self) -> Tuple[int, int, int, int, int, int, int, int]:
        """
        Get the current datetime

        (2023, 4, 18, 0, 10, 34, 4, 108)
        y,     m,  d, h, m,  s, wd, yd

        :returns:   (year, month, day, hour, minute, second, weekday, yearday)
        :rtype:     Tuple[int, int, int, int, int, int, int, int]
        """
        buf = bytearray(7)

        buf = self._i2c.readfrom_mem(self._addr, DATETIME_REG, 7)

        year = self._bcd_to_dec(buf[6]) + 2000
        month = self._bcd_to_dec(buf[5])
        day = self._bcd_to_dec(buf[4])
        yearday = self.day_of_year(year=year, month=month, day=day)
        return (
            year,
            month,
            day,
            self._bcd_to_dec(buf[2]),           # hour
            self._bcd_to_dec(buf[1]),           # minute
            self._bcd_to_dec(buf[0] & 0x7F),    # second
            self._bcd_to_dec(buf[3] - self._weekday_start),     # weekday
            yearday,
        )
...

Any help is appreciated!
