ADS1115 Comparator feature
Hi, I set up the comparator on A0 of the ADS1115 ADC module and the Alert line changes as expected. However if I try to read any other channel in single ended mode the Alert feature stops working. How can I have the comparator set on one channel and still use the other channels with normal reads?

Re: ADS1115 Comparator feature
The ADS1115 has just one ADC that is multiplexed between the channels. And it can only operate in one mode at a time. If you want to take readings on other channels, you would need to restart the comparator mode after your readings.
