I’m an electrical technician… and the reason for using individual ads1115’s is because I destroyed too many by trying to read both voltages on a single one.
So I am using 1 ads1115 to read 2 current sensors Hass 50’s. I am using 1 ads1115 to read solar panel voltage which never gets above 22vdc and 1 ads1115 to read the battery which never gets above 14vdc.
My biggest problem has been finding programmers reference manual for the ads1115’s. As I think that could be a part of my problem. I am setting the gain slightly different on the ads1115 reading the hass50’s but haven’t had an issue with that one yet… only the 2 reading the voltages.
All I can find are program examples and an ads1115 document that explains some but not everything pertaining to Arduino programming.
