import ADS1x15 results in errors

[Mr-bkmtech]

I am trying to communicate with an ADS1015 module using I2C and I get the following errors using Thonny as my editor

This is line 98:
import ADS1x15

I get the following messages:
Traceback (most recent call last):
File "", line 98, in
File "/lib/ADS1x15/init.py", line 5, in
File "/lib/ADS1x15/ADS1x15.py", line 1, in
File "/lib/smbus2/init.py", line 23, in
File "/lib/smbus2/smbus2.py", line 25, in
File "/lib/fcntl.py", line 1, in
ImportError: no module named 'ffi'

I have gone through the Thonny packages available and cannot find a package that works, or even an easily identifiable package that should work.

I am not sure how to proceed at this point!

It sounds like you're using a driver from PyPI that isn't designed for MicroPython (i.e. it's designed for a Raspberry Pi or some other Linux-based embedded system).

(As far as I understand it, Thonny will show all PyPI packages, not just MicroPython-suitable ones).

[Mr-bkmtech]

That is correct

(As far as I understand it, Thonny will show all PyPI packages, not just MicroPython-suitable ones).

Hi Robert

Could you please describe the process because I am missing something.

Maybe I am going about this the wrong way because I am trying to learn 2 things, both Micro Python and Thonny.

You can use mpremote to copy files to your board. mpremote is the official tool by MicroPython, and can be installed using upip. Using Thonny that should be possible as well. But I cannot tell you anything about Thonny.

Thonny has a menu entry like 'View'. There you may check something like 'Files' to get an extra view of the files on your computer and, as soon as you connected to the RP2, of the files on the RP2 file system. You may copy files by right-clicking on them and selecting 'copy ...'. Now you have to navigate in the upper view of files on your PC to ads1x15.py and then use the right mouse click to copy it to your RP2. Note that you can select different directories on the RP2 too. Files in the base directory '/' as well as in '/lib' should be found in an attempt to import them.
I assume that you may connect to the RP2 with Thonny (you have to select the Interpreter 'MicrPython (Raspberry Pi Pico)' under the menu entry 'Run' - 'select Interpreter' and after that perhaps several times touch the red 'Stop' icon).

Thanks

I got it working

I got it working, thank you

I will review all replies with my associate, thank you
