Hello,
Good work.
Just reporting an issue seen on my old RPi B which use i2c bus0 /dev/i2c-0

ADS1x15.ADS1115(0, i2c_address) throws error /dev/i2c-1 not found
Seems to be due to early initialisation of SMBus at

ADS1x15-ADC/ADS1x15/ADS1x15.py

Line 69 in d2f6e7f

i2c = SMBus(1)

Yes, this should be an issue if the I2C / SMBus interface 1 is not activated, and user only want to using other SMBus. So I Think We should omit i2c initialisation in line 69. The I2C is also initialized in the constructor.

Have you test to omit code in line 69?

Yes it works by removing the line.
