scd30 Documentation missing: Which Raspberry Pi's are supported?

Hi, could you provide a list of RPi's that are known to work with the library? If there are special tweaks necessary for other than RPi4, that would also be helpful. Yours S

Hi, Sorry, I do not have any other RPis at hand to test it. If you have a different model and would like to volunteer, I'm happy to help with the setup.

Based on some findings while looking into the clock stretching bug, I think all older RPis must use software I2C as their hardware I2C is inherently broken. Other than this limitation (and having to provide a software I2C interface to the library), I do not see any problems with running this on older Pis.

@RequestForCoffee Ok, I just ordered my SCD-30. Don't know how long shipping will take, but I want to use it with a Rpi3. I will get back to you with success or fail reports. I was hoping that the complications re. clock stretching could somehow be overcome.

I think they can be overcome by simply using software I2C on the GPIO pins. LMK if you run into any troubles there or think you might benefit from some API adjustments in the library to support this usecase.

I'll keep this issue around in the meantime.

I have tested it in raspberry pi P1 and appears to works correctly. I plan to mount in a zero W model

I can confirm that it works with a Raspberry Pi Zero W.
