Reading ADS1115 ADC using I2C port

Hi,

I need more ADC channels than the Navio2 already has, so I’m trying to use an external ADS1115 ADC on breakout board connected over I2C.

I’ve enabled I2C in raspi-config, and installed the ‘Adafruit Python ADS1x15’ drivers from github. The problem is when I run command ‘i2cdetect -y 1’ it doesn’t show any device connected. I presumed that the I2C port was directly routed to raspberry Pi’s normal I2C input pins, so I wouldn’t need to do anything differently. Is this true, or do I need different drivers?

Thanks for any help,
Simon
