ADS111x problems

I figured out the problem, this is not a bug, at least not a problem with the library.

Depending on how you set the ads111x_set_data_rate, you must add a delay to allow the ads1115 chip to measure the value. In my case I was setting the data rate to 8 per second (ADS111X_DATA_RATE_8) , theoretically then I must wait 125ms before reading the value. I configured it to 150ms and the values are read fine.
Another way of doing this would be to connect the alert/ready pin to get notified when the conversion is ready.

I've changed it to ADS111X_MUX_0_GND and got now good measuring values around 2890.
I've only attached 1 sensor at ADS111X_MUX_0_GND, why am I getting the same values at ADS111X_MUX_1_GND, ADS111X_MUX_2_GND and ADS111X_MUX_3_GND? I need to switch the channels for other sensors.

I had the same problem (reading the same voltage) when trying to measure a differential and a relative to ground voltage. Is there a work around to this problem?

Hey feel free to refer this repo where you will find pin diagram and corresponding code that actually works!

Hi, I see this issue is closed but i am stuck at this point. I am only able to read one analaog input channel at one time only. How can i read all four single ended channels simultaneously?
