ad1115 totally weird values when overlay ad1115 is not loaded #60

Hi,

I'm trying to use the ADS1115 driver from Circuitpython to replace the outdate old 1.0.2 one. However it seems I need to load the also outdated AD1115 overlay to make the return values make sense. Otherwise the AD1115 outputs just nonsense the values are jumping around from 20000+ to -116 in all channels.

When I add the ADS1115 overlay everthing looks perfectly fine. So it seems the overlay does some tricks (probably initialization wise) which CircuitPython is missing. How can I get rid of the overlay, do we need a better initialization function?

Cause when using dmesg output shows that ad1115 overlay is also outdated as it uses a deprecation driver add method.

Best, Marc

Are you referring to device tree overlays? What platform are you using the ADS on? Sounds like maybe this a Raspberry Pi?

In general, use of the ASD1115 does not require any special drivers or dto's. You only need to enable I2C. Everything is done over I2c via this library.
