Voltage on SQW about mpy-lib HOT 6 OPEN

Do you enable alarm interrupt or Square-Wave Output? You can try to set Control Register (0Eh) to 0x1C (default value) to disable SQW, and clear A1F/A2F (Alarm Flag) before enter deepsleep mode.

thanks for your kind reply. As I explained to you, I am not a programmer, I managed to get here only thanks to what I found on the internet. I'm sorry but I'm unable to go any further on my own.

from mpy-lib.

use ds.setReg(DS3231_REG_CTRL, 0x1C) to disable SQW, and ds.ClearALARM() to clear alarm.

from mpy-lib.

By adding
ds.setReg(DS3231_REG_CTRL, 0x1C)

gives me the following error:

File "main.py", line 27, in
NameError: name 'DS3231_REG_CTRL' isn't defined

from mpy-lib.

use
ds.setReg(DS3231.DS3231_REG_CTRL, 0x1C)

from mpy-lib.

The command does not give an error but the SQW pin always remains high.
