ADS1115 ADC via Soft I2C

Hi,
I have to connect a ADS1115 ADC to an Arduino Nano via Software I2C.
This library (Arduino Playground - SoftwareI2CLibrary) can handle soft-I2C, but the library I'm using for the ADS1115 ( Arduino Code | Adafruit 4-Channel ADC Breakouts | Adafruit Learning System ) is obviously made only for hard I2C.

Does anyone know if I could make changes in the library or show me how to read values from the ADC "manually" (without the library).

Thanks
Best regards
Axel

See my updated comments in your other post about soft serial between Mega and Nano. You might change to another ADC using SPI or serial such as the ADS7841.

In the Library Manager in the Arduino IDE, there is the 'SoftwareWire' library. After creating the object, it should be compatible with the official Arduino Wire library functions.
Why do you have to use Software I2C ? There are probably better options for your problem as Artic_Eddie already wrote.
For multiple sensors with the same I2C address, this is a lot better : TCA9548A I2C Multiplexer : ID 2717 : $6.95 : Adafruit Industries, Unique & fun DIY electronics and kits

Thanks for the replies. I "solved" the issue by redesigning my layout and were able to connect it to the ADC to the hardware I2C pins
