I can not use it on my Rasp pi4 64bits with python3.11? what's the reason? #95

Hi, I am trying to run the libs, but I encounter the issue that it can not detect INA219 or the Likes issue. I am using the Rasp pi4 64bits with the python3.11 version. but in the other same environment, python3.9, it's working. what's the reason? differency?

caternuson commented 3 months ago

This repo is for the ADS1015 and ADS1115 ADC's. Are you using either of those? You only mention the INA219, which is something different.

augustine829 commented 3 months ago

Sure, I am using the ADS 1X15 module for ADC checking. I can not detect it when I run my code.

caternuson commented 3 months ago

If you run the basic example from this library: https://github.com/adafruit/Adafruit_CircuitPython_ADS1x15/blob/main/examples/ads1x15_simpletest.py what output are you seeing in the serial output?

The output from my terminal here: raw v 16 0.002 16 0.002 16 0.002 16 0.002 16 0.002 16 0.002 16 0.002 16 0.002 16 0.002 16 0.002 16 0.002 16 0.002 16 0.002 16 0.002 16 0.002 16 0.002

It's working, so it looks like it's detecting the ADS? It's unclear what the issue is?

augustine829 commented 3 months ago

No, it can not initialize the ADS module, but I checked the voltage from the ADC pins with a multimeter.

caternuson commented 3 months ago

It's not clear what "can not initialize" means. If there were issues initializing, some form of error message(s) would be expected.

Is the issue that the values are not changing in the output?

augustine829 commented 3 months ago

The output from my program is here:

Is the basic example from the library working as expected? Are the ADC values changing?

Trouble shoot with the library example. Make sure it works before moving to your code.

It looks like you are using the ADS1115 and not the ADS1015, so try this example: https://github.com/adafruit/Adafruit_CircuitPython_ADS1x15/blob/main/examples/ads1x15_ads1115_simpletest.py

Change the channel being used as needed:

chan = AnalogIn(ads, ADS.P0)
augustine829 commented 3 months ago

ok, thanks. let me do it now.

augustine829 commented 3 months ago

I check my address 0x49 with channel-0, it outputs here:

raw v 275 0.034 276 0.034 276 0.034 276 0.034 275 0.034 273 0.034 278 0.035 279 0.035 269 0.034 274 0.034 276 0.035 273 0.034 269 0.034 276 0.034 276 0.034 275 0.035 265 0.034 277 0.035 276 0.034 273 0.035

Are you able to apply a varying voltage as well? To confirm the ADC is reading the changes.
