ESP8266 issue

[MrGadzet]

Hi,
i am trying to run this current sensor with esp8266, but i've got a lot of issues. I solved a most of the problems myself but one i can't do for 3 days.
During start program it shows me "AttributeError: 'module' object has no attribute '_level'". Code is from your example. You can see it below. The logging.py file from official micropython github from linked file in README.

from machine import Pin, I2C
from ina219 import INA219
from logging import INFO

i2c = I2C(scl=Pin(5), sda=Pin(4), freq=400000)

SHUNT_OHMS = 0.1

ina = INA219(SHUNT_OHMS, i2c)
ina.configure()
print("Bus Voltage: %.3f V" % ina.voltage())
print("Current: %.3f mA" % ina.current())
print("Power: %.3f mW" % ina.power())

Have you got any solution of this problem?

I have not seen this before, something wrong with logging module would be my suspicion, what happens if at the REPL prompt you do:

import logging

Does this work?

If it does what does:

dir(logging)

Give you?

Investigating a bit more I can see that the logging module has been updated recently and the _level attribute remove. In the commit history https://github.com/micropython/micropython-lib/commits/master/python-stdlib/logging/logging.py, you can see this in the 1st commit on 21st Dec 2022, micropython/micropython-lib@58bab0a.

So until I can update pyb_in219 to account for this, you can try versions of the logging library before this commit, perhaps the one of 27th Mar 2021 would be a good place to start, so download and install this https://raw.githubusercontent.com/micropython/micropython-lib/fa13cbbc8b53e2ec6abbb1b0fa33d085582f3c54/python-stdlib/logging/logging.py

Update to pyb_ina219 to support latest version of logging looks like it might be fairly simple, will try at the weekend.

Fix for this already in progress on PR12, am looking to complete this.

Thanks for quick reply. I tried with the commit you sent and it works.

I faced same issue reported in the OP when testing the library on a Pico W. Applied suggestion from below link (chnge in line 409) to get it working.
