Not sure how to word this. Im trying to read volts/amps using 12v DC brick and a lamp or a dc motor and I am getting odd results and not 12v etc from the basic code example.
running the code...

Sorry if this is the wrong place for help but I'm stuck.

• Arduino board: ** Raspberry Pi 4 **

• Arduino IDE version (found in Arduino -> About Arduino menu): ** Ubuntu 20.10 **

• List the steps to reproduce the problem below (if possible attach a sketch or
  copy the sketch code in too): LIST REPRO STEPS BELOW

Hi, I use the ina260_simplest.py to obtain the current. From the terminal, under Current, the values printed on the screen always have one of the following endings: .00, .25, .50, .75. Why it does not have other higher resolution values?

Also, could you please tell me how to set the conversion time to 140us? I asked a few times. Support told me to use:

ina260.ConversionTime = ConversionTime.TIME_140_us

I copied and pasted the above line but python3 gave me

NameError: name 'ConversionTime' is not defined.

Also, under what situations do we set such fast conversion time rather than just use the default value of 1.1ms? Any disadvantages in using the fastest conversion time of 140us?

Thank you

There are missing type annotations for some functions in this library.

The typing module does not exist on CircuitPython devices so the import needs to be wrapped in try/except to catch the error for missing import. There is an example of how that is done here:

try:
    from typing import List, Tuple
except ImportError:
    pass

Once imported the typing annotations for the argument type(s), and return type(s) can be added to the function signature. Here is an example of a function that has had this done already:

def wrap_text_to_pixels(
    string: str, max_width: int, font=None, indent0: str = "", indent1: str = ""
) -> List[str]:

The following locations are reported by mypy to be missing type annotations:

• adafruit_ina260.py:104
• adafruit_ina260.py:154
• adafruit_ina260.py:171

For my project we have a relay hat on the pi that is controlled by python code.

I use it with a pi4 and a pi5. If i install the INA260 library on the pi4 everything is fine.

if I install the INA260 library on a pi5 like this:

sudo pip3 install adafruit-circuitpython-ina260 --break-system-packages

(using the break packages flag was the only way i could figure out how to get it installed)

immediately the GPIO stops works and i get this error

Traceback (most recent call last):
  File "/home/pi/Desktop/Mothbox/TakePhoto.py", line 54, in <module>
    GPIO.setup(Relay_Ch1,GPIO.OUT)
RuntimeError: Cannot determine SOC peripheral base address

now the pi5 does have weird stuff with its GPIO pins, and this error comes up for instance if using the regular GPIO libraries. and so in the past i got around it by installing the lgpio library.

but now it doesn't matter if i have the lgpio library or not, whenever the ina260 library is installed it permanently breaks the setup.

also i cannot do pip3 uninstall either. it keeps it being broke. I have to flash a new image.
