I am currently using the ADS1015 as an external ADC for my infrared sensor with my Particle Electron microcontroller. I am using this external ADC so that my microcontroller can stay in sleep mode until it is triggered. Currently, my IR transistor takes readings from an IR LED that is constantly on. I would like drive my LED with PWM and have the external ADC only read on HIGH.
Is there an external ADC that can take readings based on a trigger so I can synchronize it with my LEDs PWM?
