ADS1115 Comparator feature

Post by TonyMcKenna »

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?

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.
